Chapter 19, Problem 68E

Interpretation Introduction

Interpretation:

The structure ofbeta-sheetis to be described and its category is to be identified.

Concept Introduction: Amino acids interact with each other and linked together to form proteinsby the peptide bonds.

The interaction of amino acids causes the twisting and folding of protein chains in a very specific manner and thus proteins form different types of structure.

Primary, secondary, tertiary and quaternary are four levels of protein structures.
