Amino acids are the chemical units or “building blocks,” that make up proteins. They also are the end products of protein digestion, or hydrolysis. Amino acids contain about 16 percent nitrogen. Chemically, this is what distinguishes them from the other two basic nutrients, sugars and fatty acids, which do not contain nitrogen.
