Carbohydrates are large complex molecules composed of long monosaccharide chains.Glucose exists in two forms ; alpha, the hydroxyl group faces down. Beta the hydroxyl group faces up.
Saccharides:
Monosaccharides join together with glycosidic bonds.
During synthesis water is released.
With maltose 2 glucose units are bonded together.
You can describe where bonds are with numbered Carbons and what type of glucose is involved. Maltose has an alpha, 1-4 glycosidic bond.
Starch is the main energy store for plants:
A mixture of two polysaccharides of alpha glucose Amylose and Amylopectin.
Amylose is a long unbranched chain of alpha glucose. It forms three-dimensional helix with hydrogen bonds…
