Question

What monomers are proteins made of? What is the structure of the monomer that makes up a protein?

Answer 1

proteins have amino acids as monomers

Explanation:

proteins are made up of 21 different L-amino acids. these amino acids are joined together with peptide bonds. peptide bond is a bond between a caboxylic group of one amino acid with amino group of other amino acid.

following is a figure to describe the structure of a single amino acid, where R -group is variable and can contribute for the amino acid to be neutral, acidic or basic. next figure gives an idea of how many various amino acids are there.
