A decapeptide (Mol. Wt. 769) on complete hydrolysis gives glycine (Mol. Wt. 75), alanine and phenylalanine.
Glycine contributes `47.0 %` to the total weight of the hydrolysed products. The number of glycine units. Present in the decapeptide is.

Text Solution

Verified by Experts

The correct Answer is:
6
Molecular weight of decapeptide = 796 g/mol
Total bonds to be hydrolysed = (10-l) = 9 per molecule
Total weight of `H_2O` added = `9 xx 18 = 162` g/mo
Total weight of hydrolysis products = 796+162 = 958 g
Total weight % of glycine (given) = 47%
Total weight of glycine in produc `=(958 xx 47)/100 g= 450 g`
Molecular weight of glycine = 75 g/mol
Number of glycine molecules = `450/75=6`
