Know the difference between monosaccharides, disaccharides and polysaccharides.

#1.1ii

Know the structure of the hexose glucose (alpha and beta) and the pentose ribose.

#1.1iii

Understand how monosaccharides (glucose, fructose, galactose) join to form disaccharides (sucrose, lactose and maltose) and polysaccharides (starch formed from amylose and amylopectin; glycogen) through condensation reactions forming glycosidic bonds, and how these can be split through hydrolysis reactions.

#1.1iv

Understand how the structure of glucose, starch, glycogen and cellulose relates to their function.
