Answer: Interconversion of the alpha- and beta-anomers.
- A Interconversion of the alpha- and beta-anomers
- B Oxidation of glucose to gluconic acid
- C Rotation of the whole molecule in water
- D Formation of an osazone derivative
Correct answer: A. Interconversion of the alpha- and beta-anomers
Explanation: Mutarotation is the gradual change in specific rotation as alpha-D-glucose and beta-D-glucose interconvert through the open-chain form until equilibrium is reached.
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.
