Answer to Question #339790 in General Chemistry for Nibedita Rudra

Question

Glycine can be estimated by using which method?

1. Formylation method

2. Acetylation method

3. Bromination method

4. Esterification method

Answer 1

Here we will estimate glycine by formal titration method (Soronsen's method). Amino acids like glycine, alanine, etc. contain one amino group and one carboxylic group as part of their structures.

Sørensen in 1907 is a titration of an amino acid with potassium hydroxide in the presence of formaldehyde. It is used in the determination of protein content in samples.

Answer: A Formylation method
