Glucose Fructose
Disaccharides >have two sugar units bonded together.For example,common table sugar is sucrose a disaccharide that consists of a glucose unit bonded to a fructose unit: CH2OH CH2OH H H CH2OH OH OH
Disaccharides ➢have two sugar units bonded together. For example, common table sugar is sucrose a disaccharide that consists of a glucose unit bonded to a fructose unit:
Lactose Lactose:is found CH2OH CH2OH exclusively in the milk of mammals and consists of galactose and glucose in a B-(1,4) glycosidic bond
Lactose Lactose: is found exclusively in the milk of mammals and consists of galactose and glucose in a b-(1,4) glycosidic bond
maltose Maltose:the major CH2OH CH2OH degradation product of starch,is composed of 2 glucose monomers in an a-(1,4)glycosidic bond
