Infobox references

5-Dehydroepisterol is a sterol and an intermediateinsteroid biosynthesis, particularly synthesis of brassinosteroids.[1] It is formed from episterol through action of ERG3, the C-5 sterol desaturase in the yeast[2] and is then converted into 24-methylenecholesterolby7-dehydrocholesterol reductase.[3]

Episterol and 5-dehydroepisterol are found in Leishmania.[4][5]
