Abstract
Chloroplast-rich particles of sugar beet and Euglena gracilis are able to carry out the light-, H(2)O(2)- and O(2)-independent syntheses of a nonaprenyltoluquinol, an octaprenyltoluquinol and a phytyltoluquinol from homogentisate and nonaprenyl, octaprenyl and phytyl pyrophosphate. The formation of these compounds probably takes place by the concomitant polyprenylation (or phytylation) and non-oxidative decarboxylation of homogentisate.
摘要
甜菜和纤细裸藻富含叶绿体的颗粒能够在无光、无过氧化氢和无氧的条件下，由尿黑酸与壬基焦磷酸、辛基焦磷酸和植基焦磷酸合成壬基甲苯醌、辛基甲苯醌和植基甲苯醌。这些化合物的形成可能是通过尿黑酸的多聚异戊二烯化（或植基化）和非氧化脱羧作用同时发生的。
