Chapter 5, Problem 18RQ

Summary Introduction

To review:

Levels of protein structure contributed by the following:

a) Amino acid sequence

b)β (beta)-pleated sheet

c) hydrogen bond

d) disulfide bond

Introduction:

Proteins are complex macromolecules composed of several amino acids and haveseveral levels of structural organization. Mainly there are four types of protein structure:primary structure (simplest), secondary structure, tertiary structur, end quaternary structure. All these complex structures are formed by folding of the primary structure of the protein and are stabilized by unique linkages such as disulfide bonds, hydrogen bonds, Vander Waal linkage, snd electrostatic interactions.
