4°) is more than dextrorotation of
glucose (+ 52 5°), the mixture is laevorotatory Thus, hydrolysis of
sucrose brings about a change in the sign of rotation, from dextro
(+) to laevo (–) and the product is named as invert sugar (ii) Maltose: Another disaccharide, maltose is composed of two
a-D-glucose units in which C1 of one glucose (I) is linked to C4
of another glucose unit (II)
