WebBiology questions and answers. Deamination of alanine results in the formation of what molecule (this molecule appears in glycolysis)? O pyruvate phosphoenolpyruvate … Biosynthesis Alanine can be synthesized from pyruvate and branched chain amino acids such as valine, leucine, and isoleucine. Alanine is produced by reductive amination of pyruvate, a two-step process. In the first step, α-ketoglutarate, ammonia and NADH are converted by glutamate dehydrogenase to … See more Alanine (symbol Ala or A), or α-alanine, is an α-amino acid that is used in the biosynthesis of proteins. It contains an amine group and a carboxylic acid group, both attached to the central carbon atom which also carries a See more Alanine is an aliphatic amino acid, because the side-chain connected to the α-carbon atom is a methyl group (-CH3); alanine is the simplest α-amino acid after glycine.

Pyruvate, the result of glycolysis, can feed into both the TCA cycle and fermentation processes. Reactions beginning with either one or two molecules of pyruvate lead to the synthesis of alanine, valine, and leucine. Feedback inhibition of final products is the main method of inhibition, and, in E. coli, the ilvEDA operon also plays a part in this regulation.
