1alpha-hydroxyvitamin D2

4a-Formyl-5a-cholesta-8,24-dien-3b-ol is an intermediate in the biosynthesis of cholesterol, in a reaction catalyzed by the enzyme methylsterol monooxygenase (EC 1.14.13.72, 4,4-dimethyl-5alpha-cholest-7-en-3beta-ol,hydrogen-donor:oxygen oxidoreductase (hydroxylating)). (MetaCyc).

9,10-Secoergosta-5,7,10(19),22-tetraene-3,25-diol. Biologically active metabolite of vitamin D2 which is more active in curing rickets than its parent. The compound is believed to attach to the same receptor as vitamin D2 and 25-hydroxyvitamin D3.

Amasterol is found in green vegetables. Amasterol is isolated from Amaranthus viridis (calalu

(5x,6x)-5,6-Epoxyergosta-7,22-dien-3-ol is found in mushrooms. (5x,6x)-5,6-Epoxyergosta-7,22-dien-3-ol is a constituent of Armillaria mellea (honey mushroom).

Portensterol is a constituent of Tricholoma portentosum and Clitocybe nebularis (clouded agaric)

(24S)-Ergost-4-ene-3,6-dione is found in pulses. (24S)-Ergost-4-ene-3,6-dione is isolated from Glycine max (soybean).

4α-formyl-5α-cholesta-8,24-dien-3β-ol is considered to be practically insoluble (in water) and relatively neutral. 4α-formyl-5α-cholesta-8,24-dien-3β-ol is a sterol lipid molecule

9,10-Secoergosta-5,7,10(19),22-tetraene-3,25-diol. Biologically active metabolite of vitamin D2 which is more active in curing rickets than its parent. The compound is believed to attach to the same receptor as vitamin D2 and 25-hydroxyvitamin D3.

Campest-4-en-3,6-dione belongs to ergosterols and derivatives class of compounds. Those are steroids containing ergosta-5,7,22-trien-3beta-ol or a derivative thereof, which is based on the 3beta-hydroxylated ergostane skeleton. Campest-4-en-3,6-dione is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Campest-4-en-3,6-dione can be found in date, which makes campest-4-en-3,6-dione a potential biomarker for the consumption of this food product.
