Question
Chapter 7, Problem 8P
Summary Introduction
To explain: The difference in between a hemiacetal and a glycoside.
Introduction:
Diastereomers are those stereoisomers who differ in orientation of two chiral centers due to which the isomers are not the mirror images of each other. The cyclic forms of diastereoisomeric sugars which differ at the anomeric carbon (carbonyl carbon which reacts to form hemiacetal) are known as anomers.
