Qualitative Tests for Biomolecules — NEET Biology
📚 Practice ConceptFind out a qualitative test for proteins, fats and oils, amino acids and test any fruit juice, saliva, sweat and urine for them.
Assertion (A): Amino acids are the building blocks of proteins in living organisms. Reason (R): They are called α-amino acids because both amino and carboxyl groups are attached to the β-carbon.
View solution & NCERT explanation
Correct answer: C — If assertion is true but reason is false.
The Assertion is true as NCERT confirms amino acids form proteins. However, NCERT states “Amino acids are organic compounds containing an amino group and an acidic group as substituents on the same carbon i.e., the α-carbon. Hence, they are called α-amino acids” - the Reason incorrectly mentions β-carbon instead of α-carbon.
