Ergosterol C28H44O - PubChe

  1. Ergosterol is a phytosterol consisting of ergostane having double bonds at the 5,6-, 7,8- and 22,23-positions as well as a 3beta-hydroxy group. It has a role as a fungal metabolite and a Saccharomyces cerevisiae metabolite. It is a 3beta-sterol, an ergostanoid and a member of phytosterols
  2. Ergosterol is a sterol that resides on the cell membranes of fungi and acts to maintain cell membrane integrity, similar to mammalian cholesterol. Polyene antimycotic agents (amphotericin B, nystatin) are a subset of macrolide antibiotics that bind to ergosterol on the cell membranes of fungi. The bound drug molecules form a pore in the.
  3. Ergosterol is the major product of sterol biosynthesis in fungi (and also in some trypanosomes), whereas mammalian systems synthesize cholesterol as the major membrane lipid. While both sterols play a similar role in membrane fluidity, this effect has been shown to be essential for aerobic growth of most fungi
