Histidine Biosynthesis AICAR Production

The video explains the biosynthesis of histidine, an essential amino acid not synthesized in humans. It details the unique pathway of histidine synthesis, which is distinct from other aromatic amino acids as it involves ATP and PRPP rather than chorismate. The process includes several steps with intermediates like Icar, which is also used in purine biosynthesis. The final steps involve converting intermediates to histidine through enzymatic reactions. Histidine plays roles in protein synthesis and as a neurotransmitter, and its synthesis is closely related to nucleotide metabolism.
