Amino acid molecules are made of four main elements. You may remember them from science class: carbon, hydrogen, oxygen, and nitrogen. These elements form the same amino acid structure.

Amino acids are organic compounds that serve as the fundamental building blocks of proteins. They play a crucial role in the structure, function ... phenylalanine, threonine, tryptophan, and valine.
