Hydrolysis breaks triglycerides into glycerol and fatty acids

Steps:

• Triglyceride consists of 1 glycerol bound to 3 fatty acids via ester bonds (2 saturated, 1 unsaturated).
• Hydrolysis adds water to cleave these ester bonds.
• This releases the original components unchanged: 1 glycerol and the 3 fatty acids.
• Water is a reactant, not a product.

Why B is correct:

• By definition, triglyceride hydrolysis yields 1 glycerol and its exact 3 fatty acids (2 saturated, 1 unsaturated), as per the reaction: triglyceride + 3 H₂O → glycerol + 3 RCOOH.

Why the others are wrong:

• A: Lists 3 unsaturated fatty acids (ignores 2 saturated) and water (reactant, not product).
• C: Substitutes glycogen (a polysaccharide) for glycerol and assumes all 3 unsaturated fatty acids.
• D: Identical to B, providing no distinct alternative.

Final answer: B
