Numerical Answer Type:
Enter a numerical value Answer: 372 to 372 +4 marks

Solution & Explanation

### Related Formula Standard molecular weight calculation formula system: textMolar Mass = sum (textAtom Count times textAtomic Weight) textMass = textMoles times textMolar Mass ### Core Logic Let's tabulate and sum up the constituent atoms based on the verified structural formula layout : * Counting positions meticulously yields a molecular identity formula of mathrmC_9H_10FIN_2O_4. * Calculating the total molar mass: textMass = (9 times 12) + (10 times 1) + 19 + 127 + (2 times 14) + (4 times 16) textMass = 108 + 10 + 19 + 127 + 28 + 64 = 372mathrm~g/mol

Q76 jee_main_2024_29_jan_morning Proteins and Amino Acids
Type of amino acids obtained by hydrolysis of proteins is :
  • A. beta
  • B. alpha
  • C. delta
  • D. gamma

Solution

### Core Logic Proteins are natural biopolymers. The fundamental building blocks (monomers) of all naturally occurring proteins are alpha-amino acids. In these molecules, both the amino group (-NH_2) and the carboxyl group (-COOH) are attached to the exact same carbon atom, designated as the alpha-carbon. Because they are polymers of alpha-amino acids linked by peptide bonds, the hydrolysis of proteins (acidic, basic, or enzymatic) will cleave these peptide bonds to yield the constituent alpha-amino acids. ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 12 Chemistry: Biomolecules
