What are the basic units of proteins?

In: Zoology or Animal Biology

[Edit]

Amino acids

Answer

Amino acids, of which there are about 20 basic types. Some names of different amino acids are cysteine, alanine, lysine, leucine, phenylalanine, valine, methionine and isoleucine, histidine, proline, serine, tryptophan, aspartic acid and glycine.

Amino acids are composed partly of what is known as a carboylic acid group (COOH group) and the other part an NH2 group or amine group.

Amino acids react with one another stringing themselves into chains to form polypeptides. Polypeptides react with one another to form structures (many globular) called proteins.

The seqence of amino acids is essential to the type of protein formed. For example one protein that has its amino acid chain starting alanine-alanine-lysine is a completely different protein to one that begins alanine-lysine-alanine for example.
