Ergosterol is a lipid of Sterol Lipids (ST) class. Ergosterol is associated with abnormalities such as Disintegration (morphologic abnormality), Consumption-archaic term for TB, Candidiasis, Mycoses and Iodotyrosyl coupling defect. The involved functions are known as Anabolism, sporulation, 5-(carboxyamino)imidazole ribonucleotide mutase activity, Subtraction process and Physiologic Organization. Ergosterol often locates in Pore, Membrane, Protoplasm, Plasma membrane and Endoplasmic Reticulum. The associated genes with Ergosterol are IMPACT gene, BLVRB gene, CYP51A1 gene, CDR1 wt Allele and HM13 gene. The related lipids are Sterols, Cardiolipins, Membrane Lipids, fecosterol and Phosphatidylserines. The related experimental models are Knock-out.
