What are Amino acids?
Amino acids are the molecular building blocks of Proteins and hundreds of different amino acids exist in nature. When protein is broken down by digestion the result is 22 known amino acids. Eight are essential amino acids, meaning that they must be supplied from some food or supplement source; the rest are non-essential, based on the body’s ability to synthesize them from other amino acids.
Essential amino acids are isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Non-essential amino acids are arginine, alanine, asparagine, aspartic acid, cysteine, glutamine, glutamic acid, glycine, proline, serine, and tyrosine. Other amino acids, such as carnitine, are used by the body in ways other than protein building and are often used therapeutically.
