Amino acids have similar structures. What part of an amino acid's molecular formula distinguishes the macromolecule from other amino acids? O the R-group
o the amino group
o the carboxyl group
O the nitrogenous base W

The R-group

Explanation:

Amino acids are organic compounds that combine to form proteins. There are 20 of them, out of which 9 are essential. All of them have a similar structure: they consist of an alpha (α) carbon atom bonded to an amino group (NH2), a carboxyl group (COOH), a hydrogen atom, and an R group. The R group is the organic component, a side chain, that is unique to each amino acid.

This is why the first option is the correct one.
