Macromolecules Part 2 Thornburg 2014
All carbohydrates contain C,H, and O Carbohydrates have the formula C n (H 2 O) n Glucose: C 6 H 12 O 6 Group #3: Carbohydrates Thornburg 2014
Carbohydrates are classified based on the number of sugar units in the molecule Monosaccharide-1 sugar Disaccharide-2 sugars Polysaccharide-many sugars Thornburg 2014
These are simple sugars composed of 1 sugar unit Ex: Glucose Monosaccharides Thornburg 2014
molecules composed of 2 sugar subunits Example: Maltose Disaccharides Thornburg 2014
Are carbohydrate polymers Examples: starch glycogen Cellulose Starch molecule Polysaccharides Thornburg 2014
Glycogen Thornburg 2014
Carbohydrate Functions Energy Storage– Glycogen and Starch Structure - Cellulose Provide Cellular Energy – Glucose Thornburg 2014
Lipids are organic molecules made from C,H, and O All lipids are hydrophobic (water fearing, will not dissolve in water) Group #4: Lipids Thornburg 2014
Lipids are composed of… a glycerol (a type of alcohol) head 2 or more fatty acid tails (usually 3 fatty acid tails Lipid Structure Thornburg 2014
Saturated & Unsaturated Fatty Acids Thornburg 2014
Lipid Structure Glycerol “head” Fatty Acid “tails” Thornburg 2014
Are a type of lipid composed of 4 carbon rings bonded together Act as chemical messengers in living organisms Steroids Thornburg 2014
