Proline catabolism

Proline is catabolized in two steps to yield L-glutamate gamma-semialdehyde, which can react further with glutamate to yield ornithine and alpha-ketoglutarate (annotated as a reaction of amino acid synthesis and interconversion) or with NAD+ to yield glutamate and NADH + H+ (Phang et al. 2001).

Proline 经历两步分解反应，生成 L-谷氨酸γ-半醛，该物质可进一步与谷氨酸反应，生成鸟氨酸和α-酮戊二酸（标注为氨基酸合成与互变反应），或与NAD+反应，生成谷氨酸、NADH + H+（Phang 等人，2001年）。
