Oxidativereactionsofthepentosephosphatepathway
One form of chemical energy used to drive biosynthetic reactions forward is the reducing power of the energy carrier NADPH. NADPH is essential to drive the biosynthesis of fatty acids and cholesterol for example. While NADPH is an important energy carrier and is closely related to the high-energy electron carrier NADH, NADPH is distinct from NADH in several ways. NADH in oxidative phosphorylation in mitochondria tran......閱讀全文

關于磷酸戊糖途徑的基本介紹
磷酸戊糖途徑（pentose phosphate pathway）是葡萄糖氧化分解的一種方式。由于此途徑是由6-磷酸葡萄糖（G-6-P）開始，故亦稱為己糖磷酸旁路。此途徑在細胞質中進行，可分為兩個階段。 第一階段由G-6-P脫氫生成6-磷酸葡糖酸內酯開始，然后水解生成6-磷酸葡糖酸，再氧化脫羧
