How do the molecular formulas for all the amino acids differ?

The side groups are what make each amino acid different from the others. Of the 20 side groups used to make proteins, there are two main groups: polar and non-polar. These names refer to the way the side groups, sometimes called "R" groups, interact with the environment.

The molecular formulas for all the amino acids differ - the R group or side chain.

Each amino acid has the same molecular structure with a central carbon atom, the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.

Each amino acid is exactly the same except for the R group.
little side chain represented by the will be different depending on the kind of amino acid.
For example, glycine has a hydrogen atom as its R group, whereas alanine has a methyl group (CH3).

Thus, the molecular formulas for all the amino acids differ - the R group or side chain.
