Solution

The correct option is B a4,b3,c2,d1
a) Palmitic acid is a saturated fatty acid. Its chemical formula is CH3(CH2)14COOH. Meat, cheese and diary products are the main source of the palmitic acid. It was first discovered in saponified palm oil. Excess carbohydrate in the body is converted into palmitic acid.
b) Lecithin is an essential phospholipid which is present in the body. It is composed of choline, fatty acids, glycerol, glycolipids, phospholipids, phosphoric acid and triglycerides.
c) Tryptophan is a aromatic amino acid which acts as a precursor to the neurotransmitter. It helps in biosynthesis of proteins. It also helps in the synthesis of niacin and auxin.
d) Glutamic acid is an acidic amino acid which acts as a important neurotransmitter.
So, the correct answer is option B.
