Description
Pregnenolone (P5) is a naturally occurring neurosteroid and steroidal precursor involved in the biosynthesis of various steroid hormones, including progesterone, androgens, estrogens, glucocorticoids, and mineralocorticoids. It plays a role in enzymatic steroidogenesis, serving as a key intermediate in cholesterol-derived metabolic pathways.
This compound undergoes hydroxylation, dehydrogenation, and isomerization via cytochrome P450 enzymes, leading to the formation of downstream metabolites. Pregnenolone exhibits lipophilic properties, allowing for efficient membrane permeability and transport. Metabolic clearance occurs through hepatic oxidation and conjugation, with primary excretion via renal and biliary pathways.
