Define the following terms :(a)Anomers(b)Invert sugar(c)Glycosidic linkage
Define the following terms :
(a)
Anomers
(b)
Invert sugar
(c)
Glycosidic linkage
Marking-scheme solution
(a)
Isomers which differ in the configuration of -OH at C-$\displaystyle 1$ or C-$\displaystyle 2$ of
monosaccharides.
(b)
Sucrose is dextrorotatory and its hydrolysis gives dextrorotatory glucose
and laevorotatory fructose where laevo rotation is more than dextro
rotation resulting in net rotation as laevorotatory, the product is known as
invert sugar .
(c)
Glycosidic linkage in which two or more monosaccharides are joined
together by an oxygen atom.
