Amino acids are organic compounds made up of a central carbon atom and a hydrogen atom. They are found in protein foods and are part of the building blocks of life. They are involved in numerous metabolic pathways in the cells of the body. Amino acids are also used in the production of neurotransmitters, hormones, and enzymes.
Amino acids play a variety of important roles in the body, including protection from sunlight damage, promoting wound healing, and maintaining muscle and lean tissues.
A complete protein is one with all nine essential amino acids. The most complete proteins are animal protein, such as meat, fish, and milk. Other common protein sources include eggs, quinoa, soy, and legumes. Some plants can also contain proteins, though their protein content is lower.
Some of the most essential amino acids are lysine, phenylalanine, and isoleucine. These amino acids are essential for the growth, maintenance, and repair of the body. They help maintain muscles, bone, and other lean tissues. Some studies have shown that taking essential amino acids may promote weight loss, better sleep, and enhance exercise performance.
Aside from being a source of protein, amino acids are also important in the production of hormones. The simplest of these amino acids is glycine. It is an important component of the biosynthesis of heme, a substance that plays an important role in the metabolism of proteins. It also has important effects in the biosynthesis of purines.
