Statement - I : A protein chain tends to fold in a repeating geometric structure
Statement - II : A protein chain with more number of hydrogen bonds, is having less energy.

Hydrogen bonds provide most of the directional interactions that underpin protein folding, protein structure and molecular recognition.

Hydrogen bonds and their relative strengths in proteins are of importance for understanding protein structure and protein motions. The correct strength of such hydrogen bonds is experimentally known to vary greatly from ≈5–6 kcal/mol for the isolated bond to ≈0.5–1.5 kcal/mol for proteins in solution.
