- Histidine. The essential amino acid histidine is needed for the growth and repair of tissue, particularly for the maintenance of myelin sheaths—sleeves of fatty tissue that protect nerve cells, ensuring that they're able to send and receive messages.
- Isoleucine. The essential amino acid isoleucine is one of three branched-chain amino acids (BCAAs), along with leucine and valine, that the body uses for muscle repair and growth.
- Leucine. The essential amino acid leucine is one of three branched-chain amino acids (BCAAs) that the body uses for muscle repair and growth. In fact, leucine has been studied to enhance strength performance9 and it's often considered the most important amino acid for building muscle mass.
- Lysine. The essential amino acid lysine helps produce various hormones, enzymes, and antibodies. It plays an important role in the immune system and has antiviral properties, with some research suggesting that it may be effective against herpes by improving the balance of nutrients in the body in a way that slows the growth of the virus.
- Histidine. If the name histidine seems familiar, it’s probably because this amino acid is a precursor of histamine. Although histamine is widely recognized as a critical ingredient in allergic reactions, its role in the inflammatory process is an important component of the immune response and necessary for proper immune function.
- Isoleucine. Isolecuine is one of the three branched-chain amino acids, or BCAAs, so-called because this group of amino acids consists of branched side chains—the shorter chains of atoms attached to the main chain, or backbone, of the molecule.
- Leucine. The second of the three BCAAs, leucine is the most abundant essential amino acid in muscle, where it promotes muscle growth and repair by assisting in protein synthesis.
- Lysine. Like all the other essential amino acids, lysine is required for proper protein synthesis—but it’s also needed to ensure appropriate intestinal absorption of calcium.
Of the 21 amino acids common to all life forms, the nine amino acids humans cannot synthesize are valine, isoleucine, leucine, methionine, phenylalanine, tryptophan, threonine, histidine, and lysine.
- Histidine. Histidine is an essential amino acid in children; however, this is not the case in adults unless kidney function is affected. Histidine is necessary for human growth.
- Isoleucine. Isoleucine is known for its use in supplements for endurance athletes. The three essential amino acids isoleucine, leucine, and valine constitute up to 70% of all human proteins.
- Leucine. Leucine is one of the three branch-chain amino acids. Leucine, isoleucine, and valine make up the BCAA group of essential amino acids. Leucine aids in fat metabolism without reducing muscle mass.
- Lysine. Lysine is necessary for calcium absorption and therefore essential for healthy muscle and nervous system function. Lysine additionally assists in collagen and carnitine production.
Jan 21, 2019 · The body needs 20 different amino acids to maintain good health and normal functioning. People must obtain nine of these amino acids, called the essential amino acids, through food.
Amino acids help our bodies to grow, repair body tissue, maintain immunity and produce hormones that maintain body functions. The 21 amino acids different amino acids our bodies need are: Alanine. Arginine. Asparagine. Aspartic acid. Cysteine. Glutamic acid. Glutamine. Glycine. Histidine. Isoleucine. Leucine. Lysine. Methionine. Phenylalanine.
