Document Summary

4 major categories: carbohydrates, lipids, proteins, nucleic acids. Polymers: long molecule consisting of many similar/identical subunits (monomers) linked together: synthesizing a polymer. Dehydration: removal of water molecule to form a new bond: breaking down a polymer. Hydrolysis: addition of water molecule to break a bond. Also contains carboxyl group (c=0: monomer: monosaccharides ( simple sugars ) = 1 sugar. Glucose, galactose, and fructose are all isomers = same molecular formula/different con guration: disaccharides = 2 sugars (still simple sugars) Linked by glycosidic linkage formed by dehydration reaction. Glucose + fructose = sucrose: oligosaccharides = 3-10 sugars, polysaccharides = hundreds of sugars. Storage polysaccharides: starch: plants stored energy, glycogen: animals stored energy, both starch and glycogen have the 2 ring structure of alpha glucose, polymer are helical. All lipids are hydrophobic and they behave similarly. Also known as a triacylglycerol or triglyceride: functions: Thermal insulation: how to make a fat:
