Description

Biochem/physiol Actions

Ergosterol is a biological precursor of Vitamin D2 found in cell membranes of fungi and some protists such as trypanosomes. Ergosterol may be used to study the function of anti-fungal drugs such as Amphotericin B and its analogues and to study the ergosterol biosynthesis pathway within various fungi.
