BIOL2000 Chapter Notes - Chapter 5: Photosynthesis, Hydrolysis, Glycoprotein
Document Summary
4 types of macromolecules protiens nucleic acids carbohydrates lipids. Starch- constists entirely of -glucose monomers joined by glycosidic linkages (a mix of two polysaccharides), storage role in plants. Glycogen- preforms storage role in animals, also -glucose. Chintin- is a polysaccharide that stiffens the cell walls of fungi. Peptidoglycan- gives bacterial cell walls strength and firmness. Cellulose is the most abundant organic cimpound on eath, chintin second. Monomers of polysaccharides are not capable of complementary base pairing. Photosynthesis: harvest kinetic energy in sunlight and store it in bonds of carbohydrates. Co2 + h2o + sunglihgt -> (ch2o)n + o2. C-c and c-h bonds have much higher potential energy than c-o bonds have bc the electrons are shared equally. Carbs and fats both store energy, but fats store twice as much energy per gram. Amylases- enzymes involve in breaking the -glycosidic linkiges. 3 ways monosacharides difer location of carbonyl group.
