An amino acid is the basic unit of proteins (including peptides and enzymes). The amino acid molecule is formed by an amino group and a carboxylic group linked to a carbon atom (the alpha carbon), and a side chain group that gives their identity. There are 20 natural or "standard" amino acid molecules. Generally, are grouped according to the polarity of their side chains or "R" groups. According to this classification scheme, there are three major types of amino acids:
- those with nonpolar groups. Glycine, alanine, valine, leucine, isoleucine, methionine, proline, phenylalanine and tryptophan, form this type of amino acids.
- those with uncharged polar side chains or R groups. This type is formed by the amino acids serine, threonine, asparagine, glutamine, tyrosine, and cysteine.
- those with polar side chains. This type is formed by amino acids lysine, arginine, histidine, aspartic acid and glutamic acid.

How many amino acids long is fructose?
Fructose is a saccharide, and is not constructed of amino acids
Proteins are formed of building blocks called?
Amino acids held together by peptide bonds.
Proteins are polymers formed from?
Proteins are polymers formed from amino acids, which are linked together by peptide bonds. The sequence of amino acids in a protein determines its unique structure and function. Proteins are essential for many biological processes in the body.
How many polymers do proteins have?
Proteins, also known as polypeptides, are polymers of individual amino acids (peptides). The number of amino acids in the protein chain varies widely. There are dipeptides (2 amino acids), oligopeptides (with a small number of amino acids beyond 2), and full-scale polypeptides (which typically contain many amino acids).
