What are essential and nonessential amino acids? Explain how nonessential amino acids are synthesized
Just 20 different amino acids combine to form all the proteins required by the human body. Amino acids can be categorized as essential (or indispensable), nonessential (or dispensable), or conditionally essential (or conditionally indispensable). The nine essential amino acids are those you must consume in your diet because your body cannot make them at all, or cannot make them in required amounts. For most people, the remaining 11 amino acids are nutritionally nonessential because they can be synthesized from other compounds. To do this, the body transfers an amino group from an essential amino acid to an ?-keto acid, which is, in essence, an amino acid without an amino group. This process, called transamination, results in the synthesis of the nonessential amino acids.
