| 摘 要： | Cholic acid (or 3α,7α,12α-trihydoxyl-5β-cholan-24-oic acid) and lithocholic acid (or 3α-hydroxyl-5β-cholanic-24-oic acid) are commonly occurring bile acids synthesized from cholesterol in the liver in mammals. They all possess a steroid skeleton containing four rings, three with six carbons and one with five carbons. The transformation of cholesterol to cholic acid results in two major structural changes that affect the steroid skeleton. The first is the hydrogenation of the double bond …
