1. Product Information


Ergosterol Powder is white to off-white crystalline powder. It is the precursor of vitamin D2, which can be converted into vitamin D2 after ultraviolet radiation, and vitamin D2 can prevent and treat rickets in infants and young children, and promote the absorption of calcium and phosphorus by pregnant women and the elderly. As an important component of the fungal cell membrane, it has a stable structure and strong specificity. It is more representative than glucosamine for the determination of biomass, so the biomass of fungi can be measured by detecting the content of ergosterol. It is also a raw material for the production of cortisone and progesterone, a very important raw material.

3. Functions and Applications


1) Ergosterol Provitamin D2 is an important part of the microbial cell membrane, which plays an important role in ensuring cell viability, membrane fluidity, activity of membrane-bound enzymes, membrane integrity, and cell material transport

2) It has a good fluidity of the yeast cell membrane and has a high ability to withstand freezing.

3) Most commonly used antifungal drugs are inhibitors designed for the key enzymes necessary for ergosterol biosynthesis, which inhibit the synthesis of the key enzymes by competitively binding to the key enzymes, destroying the cell membrane of the fungus, thereby inhibiting the fungus growth and reproduction.

4) It can enhance the body‵s ability to resist diseases, is an important source of fat-soluble vitamin D2, and has obvious antibacterial and anti-tumor effects [6]. The converted vitamin D2 can be added to the feed as a feed additive to increase the egg production rate and hatchability of livestock and poultry.

5) It can also be used as an important pharmaceutical and chemical raw material for the production of sterol drugs such as “cortisone” and “hormone progesterone”
