Assertion (A): Human diet should compulsorily contains glycine, serine and tyrosine. Reason (R): Essential amino acids can not be synthesized in the human body.
✓ Correct answer: d) A is false but R is true
ExplanationAssertion (A) is false: Glycine, serine, and tyrosine are non-essential amino acids which means they can be synthesized by the human body and do not need to be obtained through diet.Glycine and serine are produced from intermediate metabolites such as glucose and tyrosine is derived from phenylalanine, an essential amino acid.Hence, their dietary intake is not compulsory.Reason (R) is true: Essential amino acids are those that the human body cannot synthesize on its own and must be obtained from the diet.There are nine essential amino acids: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.These amino acids are vital for protein synthesis and other metabolic functions.465
