Common Name 17a,20a-Dihydroxycholesterol
Description 17alpha,20alpha-Dihydroxycholesterol is an intermediate in C21-Steroid hormone metabolism. 17alpha,20alpha-Dihydroxycholesterol is the 8th to last step in the synthesis of Cortolone and is converted from 20alpha-Hydroxycholesterol via the enzyme cytochrome P450 (EC 1.14.99.9). It is then converted to 17alpha-Hydroxypregnenolone via the enzyme cytochrome P450 (EC1.14.15.6).
