Quiz 2 Biochemistry:Concepts and Connections EXAM WITH QUESTIONS AND ANSWERS GRADED A+ LATEST UPDATE

- ANSWER>>His (histidine)

Histidine is an α-amino acid involved in the biosynthesis of proteins. The structure of histidine includes an α-amino acid, a carboxylic acid group, and an imidazole side chain. Histidine was initially thought to be essential only for infants; however, it has since been found to be essential for adults too.
