Top 1200 Chemical Reactions Quotes & Sayings

So many of the chemical reactions occurring in living systems have been shown to be catalytic processes occurring isothermally on the surface of specific proteins, referred to as enzymes, that it seems fairly safe to assume that all are of this nature and that the proteins are the necessary basis for carrying out the processes that we call life.

The DNA-encoded catalytic machinery of the cell can rapidly learn to promote new chemical reactions when we provide new reagents and the appropriate incentive in the form of artificial selection.

The distinction between the old and the new formulations consisting in the incorporation of the concept of the rate of chemical reactions is so great that it immediately asserted itself in the objective development of catalysis.

Biochemistry is the science of life. All our life processes - walking, talking, moving, feeding - are essentially chemical reactions. So biochemistry is actually the chemistry of life, and it's supremely interesting.

This simple idea served to provide information on the geometrical shape of reacting molecules, and I was able to make the role of the frontier orbitals in chemical reactions more distinct through visualization, by drawing their diagrams.

I was also interested in formulating the path of chemical reactions.

This would be a very good moment to institute a call for imposing the Chemical Weapons Convention on the Middle East. The actual Chemical Weapons Convention. Not the version that [Barack] Obama presented in his address to the nation and that media commentators repeat. What he said is that the convention bars the use of chemical weapons. He knows better. And so do the commentators. The Chemical Weapons Convention calls for banning the production, storage and use of chemical weapons, not just the use. So why omit production and storage?

The world of chemical reactions is like a stage, on which scene after scene is ceaselessly played. The actors on it are the elements.

You get more negative reactions than positive reactions as you go through life, and the big lesson is nobody counts you out but yourself...I never have; I never will.

Using awareness, personal responsibility and inner work to review our unskillful or frightened reactions, we become more adept at turning habitual reactions to balanced responses. These moments are very exciting and gratifying.

If you don't think your anxiety, depression, sadness and stress impact your physical health, think again. All of these emotions trigger chemical reactions in your body, which can lead to inflammation and a weakened immune system. Learn how to cope, sweet friend. There will always be dark days.

I would like to start by emphasizing the importance of surfaces. It is at a surface where many of our most interesting and useful phenomena occur. We live for example on the surface of a planet. It is at a surface where the catalysis of chemical reactions occur. It is essentially at a surface of a plant that sunlight is converted to a sugar. In electronics, most if not all active circuit elements involve non-equilibrium phenomena occurring at surfaces. Much of biology is concerned with reactions at a surface.

If there's been any use of nerve gas it's the rebels that used it. If there has been a use of chemical weapons it was Al-Qaeda that used the chemical weapons - who gave al-Qaeda the chemical weapons? Here's my theory, Israel gave them the chemical weapons.

Personally, I think that for example the chemical directive in its present form does too much damage to the chemical industry - especially the medium sized businesses - and will hurt our worldwide competitiveness.

We begin to change the dynamic of our relationships as we are able to share our reactions to others without holding them responsible for causing our feelings, and without blaming ourselves for the reactions that other people have in response to our choices & actions. We are responsible for our own behavior and we are not responsible for other people's reactions; nor are they responsible for ours.

There is something very basic to the sense of listening. The sense of hearing is the only one that operates totally from vibrations, without other physical or chemical reactions to receive the sensations.

The media and the rest of popular culture weren't recording people's reactions to 9/11; they were forcing made-up reactions down people's throats.

My Cop Stopper was a Pokémon ball that you push the button and then Tesla's coils go in and the chemical compound reactions go, so it's an electrical ball so once you throw it out the window usually, in my idea of robbing a bank, I'd go through an alley way, and what this Pokémon ball would do, is it hits the metal of the cop car .

If 90 percent or 95 percent of those - chemical stockpiles [in Syria] were eliminated, that's a lot of chemical weapons that are not right now in the hands of ISIL or Nusra or, for that matter, the regime.

This success led my theoretical group to the chemical reactivity theory, extending more and more widely the range of compound and reactions that were discussed.

I was a Dow Chemical baby. My dad designed chemical plants for Dow Chemical.

When people are telling stories on screen, you can show the reactions of people, play it off those reactions, and it can be fun. But when it's someone just giving an opinion on things, even if the opinion is kind of interesting, that is potentially deadly. It has to be really quick.

The reactions of organic magnesium compounds are of two kinds - reactions of substitution and reactions of addition.

My main thesis will be that in the study of the intermediate processes of metabolism we have to deal not with complex substances which elude ordinary chemical methods, but with the simple substances undergoing comprehensible reactions... I intend also to emphasise the fact that it is not alone with the separation and identification of products from the animal that our present studies deal; but with their reactions in the body; with the dynamic side of biochemical phenomena.

Proteins are the machinery of living tissue that builds the structures and carries out the chemical reactions necessary for life.

Anguish over the loss of a loved one or feelings of helplessness have complex roots. But in the end, they make you feel bad because they adjust your brain's chemistry. Happiness and its opposite are both electro-chemical reactions; those reactions are temporary and ineffable and could even have hidden benefits.

We are close to dead. There are faces and bodies like gorged maggots on the dance floor, on the highway, in the city, in the stadium; they are a host of chemical machines who swallow the product of chemical factories, aspirin, preservatives, stimulant, relaxant, and breathe out their chemical wastes into a polluted air. The sense of a long last night over civilization is back again.

But the prospects of designing chemical plants for industrial scale chemical processes seemed far less interesting than the chemical events that occur in biological systems.

But the nature of my main work in chemistry can be better represented by more than 280 English publications, of which roughly 200 concern the theory of chemical reactions and related subjects.

I always had good reactions from people with a good eye and a vision... and very terrible reactions from those who are afraid of people who are different to others - at the beginning and even now. I have never worried about it too much.

When his brain died, all of the memories held in his gray matter, along with all of the knowledge he had acquired, would simply evaporate in a flood of chemical reactions.

When you lose your freedom, you are alone with your emotions and reactions... you can see, for example, the bad reactions you have in front of others or the way you could be dismissive or harsh.

Enzymes - plainly the most important biotechnology of our era - already permeate many industrial processes. Unlike fossil fuels, they carry chemical programming which drives complex reactions, are renewable, and work at ordinary pressures and temperatures.

Chandresh relishes reactions. Genuine reactions, not mere polite applause. He often values the reactions over the show itself. A show without an audience is nothing, after all. In the response of the audience, that is where the power of performance lives.

Radioactivity is shown to be accompanied by chemical changes in which new types of matter are being continually produced. .... The conclusion is drawn that these chemical changes must be sub-atomic in character.

LSD is really just a small chemical modification of a very old sacred drug of Mexico. LSD belongs, therefore, by its chemical structure and by its activity, in the group of the magic plants of Mesoamerica. It does not occur in nature as such, but it represents just a small chemical variation of natural material.

If you don’t think your anxiety, depression, sadness and stress impact your physical health, think again. All of these emotions trigger chemical reactions in your body, which can lead to inflammation and a weakened immune system. Learn how to cope, sweet friend. There will always be dark days.

The chemical differences among various species and genera of animals and plants are certainly as significant for the history of their origins as the differences in form. If we could define clearly the differences in molecular constitution and functions of different kinds of organisms, there would be possible a more illuminating and deeper understanding of question of the evolutionary reactions of organisms than could ever be expected from morphological considerations.

Worry is just about the worst form of mental activity there is-next to hate, which is deeply self destructive. Worry is pointless. It is wasted mental energy. It also creates bio-chemical reactions which harm the body, producing everything from indigestion to coronary arrest, and a multitude of things in between.

The United States, a signatory to the Chemical Weapons Convention, destroyed the last of its stocks of VX and other chemical agents on the Johnston Atoll, 825 miles southwest of Hawaii, in November 2000.

Some time ago we discovered the carbon cycle - a long-term set of chemical reactions that govern climates based on how much carbon is free in the atmosphere. At that point, it became clear that humans were affecting our environments far more profoundly than we realized. By releasing so much carbon and greenhouse gas into the environment, we're making long-term changes to every aspect of the natural world.

Be present as the watcher of your mind - of your thoughts and emotions as well as your reactions in various situations. Be at least as interested in your reactions as in the situation or person that causes you to react.

I have terrible chemical allergies, and I'm constantly battling unsightly reactions.

The steady states of the fluid matrix of the body are commonly preserved by physiological reactions, i.e., by more complicated processes than are involved in simple physico-chemical equilibria. Special designations, therefore, are appropriate:—“homeostasis” to designate stability of the organism; “homeostatic conditions,” to indicate details of the stability; and “homeostatic reactions,” to signify means for maintaining stability.

[G]enes make enzymes, and enzymes control the rates of chemical processes. Genes do not make "novelty seeking" or any other complex and overt behavior. Predisposition via a long chain of complex chemical reactions, mediated through a more complex series of life's circumstances, does not equal identification or even causation.

We found out that we were dealing with a completely unregulated chemical, this chemical PFOA. This was a chemical that was a completely manmade material invented right after World War Two, didn't exist on the planet prior to the 1940s.

I like something about George W. Bush. A lot. After spending more than a decade having almost physiological-chemical reactions anytime I saw him, getting the heebie-jeebies whenever he spoke - after being sure from the start that he was a Gremlin on the wing of America - I really like the paintings of George W. Bush.

And, as a consequence of the pressure that we've applied over the last couple of weeks, we have Syria -- for the first time -- acknowledging that it has chemical weapons, agreeing to join the convention that prohibits the use of chemical weapons, and the Russians -- their primary sponsors -- saying that they will push Syria to get all of their chemical weapons out. The distance that we've traveled over these couple of weeks is remarkable.

Laboratory experiments, field observations and atmospheric modeling calculations have now established that chemical reactions occurring on PSC particles play a central role in polar ozone depletion.

If the results of the present study on the chemical nature of the transforming principle are confirmed, then nucleic acids must be regarded as possessing biological specificity the chemical basis of which is as yet undetermined.

Fear and its accompanying emotional reactions have become part of the public mindset. Such reactions, while often legitimate, are also being exploited with increasing frequency for political ends.

Since it is proposed to regard chemical reactions as electrical transactions in which reagents act by reason of a constitutional affinity either for electrons or for atomic nuclei, it is important to be able to recognize which type of reactivity any given reagent exhibits.

Through the continued accumulation of detailed and reliable knowledge about elementary reactions, we will be in a better position to understand, predict and control many time-dependent macroscopic chemical processes which are important in nature or to human society.

The secret of life does not lie in its chemical basis . . . Life succeeds precisely because it evades chemical imperatives.

The cell, too, has a geography, and its reactions occur in colloidal apparatus, of which the form, and the catalytic activity of its manifold surfaces, must efficiently contribute to the due guidance of chemical reactions.

My ambition was to bring to bear on medicine a chemical approach. I did that by chemical manipulation of viruses and chemical ways of thinking in biomedical research.

Land degradation did not start with chemical agriculture. But chemical agriculture offered new tools for annihilation.

As other authors have realized, heat can have a strange effect on us, can cause odd chemical reactions in the brain. Heat can bring out secrets; it can change people's personalities.

Israel produces and stores chemical weapons. So therefore the US will prevent the Chemical Weapons Convention from being imposed on the Middle East. But it's necessary to evade this by misrepresenting the convention, and I think maybe 100 percent of the media, or close to it, go along. But that's a critical issue. Actually, Syria's chemical weapons were developed largely as a deterrent to Israeli nuclear weapons. Also, not mentioned.
