Essential amino acids are amino acids that cannot be synthesized by the body and must be obtained from the diet. There are nine essential amino acids: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Non-essential amino acids, on the other hand, are amino acids that the body can produce on its own, so they do not need to be obtained from the diet. There are 11 non-essential amino acids: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine. Both essential and non-essential amino acids are crucial for the synthesis of proteins and other important molecules in the body. **
