In esterification OH comes from_______________?
Correct answer: B. Alcohol
- A. Organic acid
- B. Alcohol
- C. Water
- D. Sugar
Explanation
During esterification, the hydroxyl group that remains in the ester-forming reaction comes from the alcohol, while the acid contributes its carbonyl-containing acyl group; water is released overall. The likely mistake is water, because water is a product of condensation rather than the source of the alcohol hydroxyl group in the textbook reaction.

About Lipids
Lipids include fats, oils, waxes, phospholipids and steroids, which are largely insoluble in water and soluble in organic solvents. Coverage includes glycerol and fatty acids, ester bond formation, saturated and unsaturated fats, triglyceride functions, and phospholipids in cell membranes.
