2

types of carbohydrates

monosacchrides, disacchrides, polysacchrides

3

monosacchrides

simple, soluble, sweet -glucose

4

disacchrides

soluble, sweet -sucrose, lactose, maltose

5

polysacchrides

large, insoluble, not sweet -starch (plant seeds) -glycogen (animals liver and muscle) -cellulose (plant cell wall)

6

fats

3 fatty acids + glycerol
insoluble
give double energy of carbohydrates

7

uses of fats

energy, insulation, germination in plants

8

proteins

chains of amino acids
some soluble; hemoglobin, insoluble; keratin

9

water

75% of body
universal solvent

10

uses of water

-transport glucose in plasma
-dissolve wastes like urea
-dissolve enzymes and nutrients for digestion
