In a transamination reaction

WebThe transamination reaction consists of two half-reactions: the amino group of the first amino substrate is transferred to PLP to produce pyridoxamine 5′-phosphate (PMP) and keto acid (ketone). In the second step, the keto substrate accepts the amino group of PMP to yield a new amino acid (amine) and regenerates PLP [ 5 , 8 ]. WebApr 9, 2024 · Figure 18.3 B. 1: The Transition Reaction between Glycolysis and the Citric Acid Cycle. Before the pyruvates from glycolysis can enter the citric acid cycle, they must undergo a transition reaction. The 3-carbon pyruvate is converted into a 2-carbon acetyl group with a carboxyl being removed as CO 2. The acetyl group is attached to coenzyme …
