Protein AA refers to amino acids that are essential building blocks of proteins. Proteins are complex organic compounds that perform a wide range of biological functions in living organisms, including providing structure to cells and tissues, catalyzing biochemical reactions, and acting as signals and messengers within the body. Amino acids are the individual units that make up proteins, and protein AA specifically refers to the specific types of amino acids that are crucial for protein synthesis.
There are 20 commonly occurring amino acids that are found in proteins, each characterized by a unique chemical structure and properties. These amino acids include alanine, arginine, asparagine, aspartic acid, cysteine, glutamine, glutamic acid, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine.
Protein AA is often used to indicate the amino acid composition of a particular protein or describe the essential amino acids that must be obtained from dietary sources, as the human body is incapable of producing them endogenously. Protein AA is involved in various biological processes and play critical roles in supporting growth, repairing tissues, regulating metabolism, preserving immune function, and numerous other physiological functions. Understanding protein AA is fundamental to comprehending the molecular basis of proteins and their functions in living systems.
