1. Fig 17.8 Biosynthesis of amino acids

2. Table 17.1

3. A. Alanine, Asparagine, Aspartate, Glutamate and Glutamine
Pyruvate is the amino-group acceptor in alanine synthesis

4. Oxaloacetate is the amino-group acceptor in the synthesis of aspartate

5. Synthesis of asparagine

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

9. Fig 17.11
Compounds formed from serine and glycine

10. Fig 17.12
Cysteine biosynthesis from serine in bacteria, plants

11. Fig 17.13 Cysteine biosynthesis in mammals

12. 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
