What are enzymes?

Basically, enzymes are a group of proteins that are able to catalyze reactions. Not all proteins have this property: there are structural proteins, or transport proteins, for instance.

Can proteins be enzymes?

proteins as enzymes An introduction to how some proteins function as enzymes, and the general features of enzyme catalysis PROTEINS AS ENZYMES This page is an introduction to how proteins can work as enzymes – biological catalysts.

Are enzymes amino acids?

Lately, it has been found that some other molecules too have an ability to speed up chemical reactions, but, as a rule, only catalytic proteins are called enzymes by scientists. Are Enzymes Amino Acids? No, enzymes are not amino acids. Amino acids are relatively simple organic molecules. Enzymes, however, are very complex.

What determines the three-dimensional structure of an enzyme?

This, in turn, determines the three-dimensional structure of the enzyme, including the shape of the active site. The secondary structure of a protein describes the localized polypeptide chain structures, e.g., α-helices or β-sheets. The complete three-dimensional fold of a polypeptide chain into a protein subunit is known as its tertiary structure.
