Amino acids are the building blocks of proteins, and their derivatives play a pivotal role in metabolic pathways. d,l-α-Ketoisoleucine is particularly relevant in the context of branched-chain amino acids (BCAAs), which are essential for muscle protein synthesis and energy production. The presence of the keto group in its structure allows it to participate in the transamination process, where it can be converted into other amino acids or energy substrates, particularly during periods of fasting or intense exercise.
