Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs. … These proteins provide structure and support for cells. On a larger scale, they also allow the body to move.
Why do so many proteins exist?
Because amino acids can be arranged in many different combinations, it’s possible for your body to make thousands of different kinds of proteins from just the same 21 amino acids.
Why do proteins form?
Proteins form by amino acids undergoing condensation reactions, in which the amino acids lose one water molecule per reaction in order to attach to one another with a peptide bond. By convention, a chain under 30 amino acids is often identified as a peptide, rather than a protein.
