Chapter 10: Q3P (page 230)

Write the chemical reactions whose equilibrium constants are $K_{b 1}$ and $K_{b 2}$ for the amino acid proline. Find the values of $K_{b 1}$ and $K_{b 2}$ -

Short Answer

Expert verified

The values are $K_{1}$ or $K_{2} = 10^{- p K a}$ .

Step by step solution

Definition of amino acid.

Amino acids are chemical molecules possessing amino and carboxylate $- CO - 2$ functional groups, as well as a particular side chain for each amino acid.

The values of Kb1and Kb2.

First write the following reactions of protonation

(1) NH - {CH}_{2})_{3} - CH - {COO}^{-} + H_{2} O □ + {NH}_{2} - {({CH}_{2})}_{3} - CH - {COO}^{-} + {OH}^{-} (1) NH - {CH}_{2})_{3} - CH - {COO}^{-} + H_{2} O □ + {NH}_{2} - {({CH}_{2})}_{3} - CH - COOH + {OH}^{-}

Next find the values of $K_{b 1}$ and $K_{b 2}$ for the amino acid proline $(K_{W} = 10^{- 14})$ :

$K_{2} = 2.288 \times 10^{- 11} S o K_{b 1} = K_{w} I K_{2} = 4.37 \times 10^{- 4} K_{1} = 0.011198 S O K_{b 2} = K_{w} I K_{1} = 8.93 \times 10^{- 13}$

values of $K_{1}$ and $K_{2}$ are found on Table $10 - 1$ as $p K_{2}$ and converted with the formula: $K_{1}$ or $K_{2} = 10^{- p K a}$
