Phospholipids are formed by the esterification of
1 three ethanol molecules with three fatty acid molecules.
2 one glycerol and two fatty acid molecules.
3 one glycerol and three fatty acid molecules.
4 one ethylene glycol and two fatty acids molecules.
Explanation:
Exp: B Phospholipids are formed by the esterification of one glycerol and two fatty acid molecules. The structure is typically made of a glycerol back bone, 2 fatty acid and tails (hydrophobic) and a phosphate group (hydrophilic).

Spoilage of oil can be detected by which fatty acid?
1 Oleic acid
2 Linolenic acid
3 Linoleic acid
4 Erucic acid
Explanation:
Exp: D Spoilage of fat oil can be detected by erucic acid. It is a monosaturated omega -9 fatty acid. It is found in more concentrations in oil and easily degraded by micro organisms and produces a foul smell and taste.

Hydrolysis of lipid yields :
1 fats
2 fatty acids and glycerol
3 mannose and glycerol
4 maltose and fatty acid
Explanation:
Exp: B Hydrolysis of lipid yields is fatty acid and glycerol. Hydrolysis can break down a fat or oil and release the tri-glycerol and fatty acids.
