C22H30O2 (326.224568)

15beta-Hydroxydesogestrel is a metabolite of desogestrel. Desogestrel is a molecule used in hormonal contraceptives. Most combined oral contraceptive pills (COCPs, or simply OCs) on the market today contain both an estrogen compound (ethinyl estradiol is common) plus a progestin (a progesterone-like compound) such as desogestrel. Desogestrel-containing birth control pills are sometimes referred to as third generation oral contraceptives. In contrast, birth control pills that are considered second generation (Tri-Levlen, for example) contain an estrogen and a progestin, but the progestin is different, such as levonorgestrel.

C22H30O2 (326.224568)

Apo-14-zeaxanthinal is a member of the class of compounds known as diterpenoids. Diterpenoids are terpene compounds formed by four isoprene units. Apo-14-zeaxanthinal is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Apo-14-zeaxanthinal can be found in a number of food items such as pepper (c. annuum), yellow bell pepper, italian sweet red pepper, and orange bell pepper, which makes apo-14-zeaxanthinal a potential biomarker for the consumption of these food products.
