What are the types of amino acids

Amino acid is the basic unit of protein. It is an organic acid containing amino group. It is composed of carbon, hydrogen, oxygen and other elements. The protein in the feed cannot be directly used by animals, but is decomposed into peptone and peptides by the combined action of digestive enzymes such as pepsin and trypsin, and cannot be used by the organism until the simplest amino acid. Therefore, protein nutrition is actually amino acid nutrition.
