b) What are polysaccharides? Give an example. (2)
c) Name any one vitamin that is stored in liver and adipose tissues. (1)

Question

Accepted Answer

> [!TLDR]
> Maltose is two α-D-glucose units linked α-1,4 (drawn as two Haworth pyranose rings joined by an O bridge); polysaccharides are long chains of many monosaccharides such as starch; a fat-soluble vitamin stored in liver/adipose tissue is Vitamin A.

**a) Haworth structure of maltose**

Maltose is a disaccharide made of **two α-D-glucose units** joined by a **C1–C4 α-glycosidic linkage**. In Haworth projection it is drawn as two six-membered glucose (pyranose) rings connected through an oxygen bridge between C-1 of the first ring and C-4 of the second ring: …
