Fig 17.8 Biosynthesis of amino acids
Table 17.1
A. Alanine, Asparagine, Aspartate, Glutamate and Glutamine
• Pyruvate is the amino-group acceptor in alanine synthesis
Oxaloacetate is the amino-group acceptor in the synthesis of
aspartate
Synthesis of asparagine
B. Serine, Gycine, and Cysteine
• Fig 17.9 Serine is derived from the glycolytic intermediate 3-phosphoglycerate
Fig 17.9 (continued)
(from previous slide)
Fig 17.10 Biosynthesis of glycine
Fig 17.11
• Compounds formedfrom serine and glycine
Fig 17.12
• Cysteine biosynthesis from serine in bacteria, plants
Fig 17.13 Cysteine biosynthesis in mammals
17.5 Synthesis of Essential Amino Acids
• Pathways have largely been determined from studies with bacteria
• Plants are thought to synthesize essential amino acids by similar pathways
D. Tyrosine
