Chapter 18, Problem 18.77SP

(a)

Interpretation Introduction

Interpretation:

The position of lactone group that forms the ring is to be stated.

Concept introduction:

In the family of macrolide antibiotics, they all have large ring (macrocycle) and an ester is present that makes the ring. A cyclic ester is known as lactone.

Amphotericin B is used as an anti fungal infections treatment. Amphotericin B is the example of macrolide antibiotics. In amphotericin B, a cyclic ester is present.

(b)

Interpretation Introduction

Interpretation:

An explanation corresponding to fact that the type of functional groups that are circled in the given Figure are to be stated.

Concept introduction:

Amphotericin B is the example of macrolide antibiotics. In amphotericin B, a cyclic ester is present. Amphotericin B is used as an anti fungal infections treatment. In Amphotericin B, the other functional groups like hemiketal and glycosidic bond is also present.
