Common Name

17a-Hydroxypregnenolone

Description

17a-17a-17a-hydroxypregnenolone belongs to the class of organic compounds known as gluco/mineralocorticoids, progestogins and derivatives. These are steroids with a structure based on a hydroxylated prostane moiety. Thus, 17a-17a-hydroxypregnenolone is considered to be a steroid lipid molecule. 17a-17a-17a-hydroxypregnenolone exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. 17a-17a-17a-hydroxypregnenolone participates in a number of enzymatic reactions, within cattle. In particular, 17a-17a-17a-hydroxypregnenolone can be converted into 17-hydroxyprogesterone; which is mediated by the enzyme 3-beta-HSD 1. In addition, 17a-17a-17a-hydroxypregnenolone can be biosynthesized from pregnenolone through the action of the enzyme steroid 17-alpha-hydroxylase/17,20 lyase. In cattle, 17a-17a-hydroxypregnenolone is involved in the metabolic pathway called the steroidogenesis pathway. 17a-17a-17a-hydroxypregnenolone is a potentially toxic compound.

Enzyme Details

1. Steroid 17-alpha-hydroxylase/17,20 lyase

General function:: Secondary metabolites biosynthesis, transport and catabolism
Specific function:: A cytochrome P450 monooxygenase involved in corticoid and androgen biosynthesis. Catalyzes 17-alpha hydroxylation of C21 steroids, which is common for both pathways. A second oxidative step, required only for androgen synthesis, involves an acyl-carbon cleavage. The 17-alpha hydroxy intermediates, as part of adrenal glucocorticoids biosynthesis pathway, are precursors of cortisol. Hydroxylates steroid hormones, pregnenolone and progesterone to form 17-alpha hydroxy metabolites, followed by the cleavage of the C17-C20 bond to form C19 steroids, dehydroepiandrosterone (DHEA) and androstenedione. Has 16-alpha hydroxylase activity. Catalyzes 16-alpha hydroxylation of 17-alpha hydroxy pregnenolone, followed by the cleavage of the C17-C20 bond to form 16-alpha-hydroxy DHEA. Also 16-alpha hydroxylates androgens, relevant for estriol synthesis. Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (CPR; NADPH-ferrihemoprotein reductase).
