The term divergent catalysis describes different catalytic chemical reactions that occur with the same substrates (reactants) under controllable conditions, especially using different catalysts. Various substrates were found to work with versatile reactivity under different catalytic conditions, resulting in ...
What is a catalyst in a chemical reaction? In chemistry, catalyst is any product that increases the rate of a reaction without being absorbed by itself. Naturally occurring enzymes are catalysts responsible for certain important biochemical reactions. ...
A chemical reaction is a process of converting one chemical into another with the help of several enzymes or catalysts; a chemical that involves in the reaction is known as the reactant, while the chemical that produces after the reaction ...

major structural elements of cells. They also serve as transporters, moving nutrients and other molecules in and out of cells, and asenzymesandcatalystsfor the vast majority ofchemical reactionsthat take place in living organisms. Proteins also formantibodiesandhormones, and they influencegeneactivity....
Reaction mechanism, in chemical reactions, the detailed processes by which chemical substances are transformed into other substances. The reactions themselves may involve the interactions of atoms, molecules, ions, electrons, and free radicals, and they
enzymes act as biological catalysts (biocatalysts). catalysts accelerate chemical reactions. the molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. almost all metabolic processes in the cell need enzyme catalysis...
Catalysis is the foundation of the chemical industry and a great effort is made to discover or fabricate efficient, economical catalysts. It is also the foundation of life, because the biological catalysts known as enzymes (elaborate protein molecules) control almost every aspect of an organism's ...
Enzymes are biological catalysts that can increase the rate of chemical reactions in living organisms. Enzymes can only function in suitable conditions of specific pH, pressure, and temperature. They are highly specific and effective for each chemical reaction in the body. Enzymes act on substrates ...
[reaction: see text] We report here our observation that, using appropriate reaction conditions, the Sonogashira reaction can be performed without the need for transition-metal catalysts. Our approach involves the use of water as a solvent, poly(ethylene glycol) as a phase-transfer agent, and so...
