A. Alanine, Asparagine, Aspartate, Glutamate and Glutamine
• Pyruvate is the amino-group acceptor in alanine synthesis
![Page 4: Fig 17.8 Biosynthesis of amino acids. Table 17.1.](https://reader036.fdocuments.in/reader036/viewer/2022062314/56649f055503460f94c1a5bf/html5/thumbnails/4.jpg)
Oxaloacetate is the amino-group acceptor in the synthesis of
aspartate

B. Serine, Gycine, and Cysteine
• Fig 17.9 Serine is derived from the glycolytic intermediate 3-phosphoglycerate

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
