Question

On hydrolysis, all lipids yield
A. Monocarboxylic acids
B. Monohydric alcohols
C. Monohaloalkanes
D. Enzymes

Answer 1

Hint: Lipid is made of an ester. Hydrolysis reactions take place in the presence of water. All the ester on hydrolysis gives carboxylic acid and alcohol as major products.

Complete step by step solution:
Lipids are actually fatty, oily or waxy type compounds present in the human and animal body. It is soluble in organic solvent as well as in many non polar solvent but lipid is actually insoluble in polar solvents such as water.

On reduction lipid breaks into fat. Fat acts as the energy bank in our body. Fat is solid lipid. It is generally present below the dermis of our skin as subcutaneous fats.

The lipids present in the animal and human body give maximum energy in the metabolic processes. On reduction lipids get converted into fatty acids. Thus, the energy content of fat or lipids is nearly twice that of carbohydrates and proteins.

Lipids are made up of ester. On hydrolysis in presence of an enzyme called lipase lipid breaks down into triglyceride an alcohol and an acid. The acid is monocarboxylic acid.
Thus the correct option is A.

Note: Carbohydrates, protein, and lipids are the energy source in our body but lipids give the maximum energy in the metabolic process of our body. Lipids break down into fat and fat gives energy.
