Macromolecules
• Polymers (Gr. many parts)
• Monomers (single parts)
• Hierarchical organization– Structure = function– Uniqueness of organsims
Carbohydrates
• Monosaccharides– Single carbohydrate units
– Formula = (X)CH2O
• Glucose = C6H12O6
– Hydroxal group - OH– Carbonyl group –COH– Combine to form
polysaccharides
Straight chain
Cellulose
• Most abundant organic polymer on earth.
• Glucose polymer
• Undigestable by most animals– Hooked together differently– Symbiotic relationship
Lipids
• Energy storage Molecule
• Mainly C & H atoms– Nonpolar– Hydrphobic
• Fatty acid molecules– General formula = (CH2)n
– Carbon chain attached to carboxyl group
Proteins• Structural building blocks of life• 7 Classes
– Structural– Contractile– Storage– Defense– Transport– Signaling– Enzymes
