Answer: Anomers (differ at the anomeric carbon).
- A Anomers (differ at the anomeric carbon)
- B Enantiomers, being exact mirror images of each other
- C Diastereomers differing in configuration at every chiral centre
- D Constitutional isomers with different connectivity of atoms
Correct answer: A. Anomers (differ at the anomeric carbon)
Explanation: Alpha and beta glucose differ only in the configuration at C-1 (anomeric carbon) and are called anomers.
Two amino acids join via a condensation reaction: the carboxyl -OH of one and an amine -H of the other are eliminated as water, leaving a peptide bond (-CO-NH-) linking them into a dipeptide; repeating this builds a full protein chain.
Concept context
The chemistry of life: carbohydrates, proteins, lipids, nucleic acids, enzymes, and vitamins. Understand their structures, classification, and biological functions. Highly relevant for NEET and Class 12 board exams.
