A protein is a sequence of amino acids joined together to form a single molecule, and consequently amino acids are everywhere in our biochemistry. Their presence influences many processes, and the complexity of cellular biochemistry continues to ensure that relatively little of this is anywhere near completely mapped. Circulating amino acid levels, as measured in blood samples, have received more attention in the context of aging and longevity in recent years. There are a few hundred different amino acids beyond the twenty used to manufacture proteins, some of which must be obtained via diet as they are not synthesized by our biochemistry. Researchers have found a number of associations between specific amino acid levels and aging, as well as demonstrating that supplem…
