Aromatase Enzyme Activity

Meaning

Aromatase Enzyme Activity refers to the biological function of the enzyme cytochrome P450 19A1 (CYP19A1), which catalyzes the final, rate-limiting step in the biosynthesis of estrogens from androgen precursors. This critical enzymatic process involves the conversion of testosterone into estradiol and androstenedione into estrone. The level of aromatase activity significantly influences the circulating ratio of androgens to estrogens, impacting hormonal balance in both males and females. Excessive activity can lead to estrogen dominance and is a target for therapeutic intervention in several clinical settings.
