what is the chemical nature of enzyme?

Answer 1

Enzymes are proteins that catalyze (i.e. accelerate) chemical reactions.
Proteins are relatively large organic compounds made of amino acids arranged in a linear chain and joined together by peptide bonds between the carboxyl and amino groups of adjacent amino acid residues.
An amino acid is any molecule that contains both amine and carboxyl functional groups

Answer 2

The events of enzymes are desperate by ability of their 3-dimensional shape.[7] maximum enzymes are plenty larger than the substrates they act on, and easily an quite small factor of the enzyme (around 3–4 amino acids) is on the instant in touch in catalysis.[8] The area that is composed of those catalytic residues and binds the substrate and then consists of out the reaction is commonplace by way of fact the lively website. some enzymes additionally contain web content that bind cofactors, that are mandatory for catalysis. some enzymes even have binding web content for small molecules, that are many times direct or oblique products or substrates of the reaction catalyzed. This binding can serve to extend or shrink the enzyme's activity, offering a ability for remarks regulation. like each proteins, enzymes are made as long, linear chains of amino acids that fold to produce a 3-dimensional product. each and each unique amino acid sequence produces a different shape, which has unique residences. individual protein chains could on occasion team at the same time to form a protein complicated. maximum enzymes could be denatured—this is, spread out and inactivated—by ability of heating, which destroys the 3-dimensional shape of the protein. reckoning on the enzyme, denaturation could be reversible or irreversible.

Answer 3

an enzyme is a protein that decreases the amount of energy required to reach a transition state in a chemical reaction. This, ultimately, will sufficiently accelerate the reaction

Answer 4

They are proteins.
