The structures of amino acids differ from each other in that:
a. they each have different acid groups
b. they each have a different side chain.
c. some do not contain carbon.
d. they do not contain hydrogen.
e. some do not contain nitrogen.

B

Explanation:

Amino acids have a basic skeleton as shown in the illustration.An alpha carbon bonded to a carboxyl gorup, amino grpup, hydrogen, and a side chain. However, amino acids differ in their side chains. These side chains can give different amino acids different properties because of their different properties. The side chains give different properties to the amino acid such as size, shape, ionization properties,  polarity, charge, acidity, and basicity.

b. Due to the presence of different side chain, amino acids structures show variation.

Amino acids are natural atoms which are considered as monomers of protein as they combine with one another and lead to the formation of protein. Amino acids are basic to life in light of fact that the proteins they structure are engaged with essentially all cell capacities.

Every amino acid has the alpha carbon attached to a hydrogen molecule, carboxyl gathering, and amino gathering in common whereas the “R” group or the amino acid side chain causes the difference.
