WebCompared to ethanol, methanol has a greater acidity, which is also somewhat higher than water. Key Differences 1. Formulas for chemicals Ethanol, often known as ethyl alcohol, has the formula CH3CH2OH and comprises two carbon atoms. Methanol, commonly known as methyl alcohol, comprises just one carbon atom. It has the chemical formula CH3OH. 2. WebEthanol at 1% did not inhibit CYP1A2, CYP3A4, CYP2C8, and CYP2C9. DMSO inhibited CYP3A4, CYP2C19, and CYP2D6 by 15 to 25% at 0.1%. However, DMSO had little effect on CYP1A2, CYP2A6, and CYP2C8. Acetonitrile, like methanol, did not inhibit any P-450 activity at 0.3% solvent except for CYP1A1 (26%) and CYP2B6 (13%).
