Monomers and polymers

Monosaccharides

-Monomers from which larger carbohydrates are made.

-Consists of a single sugar molecule with formula CH2O

-Eg glucose, galactose, fructose

-Condensation reaction between two monosaccharides form a glycosidic bond

Disaccharides

-Formed from the condensation between two monosaccharides

-Maltose is a disaccharide formed by two glucose

-Sucrose is a disaccharide formed by a glucose and a fructose

-Lactose is a disaccharide formed by a glucose and a galactose

Isomers of glucose

Polysaccharides

-Formed by the condensation of many glucos units

-Glycogen and starch are formed by the condensation of alpha glucose

-Cellulose is formed by the condensation of beta glucose
