BIO 111 Lecture Notes - Lecture 4: Cell Nucleus, Fructose, Polysaccharide
Document Summary
Bio 111 lecture 5 - january 24, 2017. Carbon can bond to four other molecules, can all be different. Co2, double bonds, four electrons are being shared on each side. Hydrocarbons- a series of hydrogen bonded to carbon. Provides a lot of diversity in living things can change shape and size of the hydrocarbon skeletons. Polymers- what make up the biomolecules (legos) each individual brick is a monomer. Dehydration reaction -takes out or forms water takes one hydrogen from a monomer, and reacts with a hydroxyl group from another monomer covalent bonds form the building blocks in polymers. Hydrolysis- to take apart a polymer, input water, and breaks apart the covalent bond, restores hydrogen to monomer and hydroxyl group back to other monomer. Large molecules: proteins (polypeptides), nucleic acids, carbohydrates (polysaccharides), lipids. Monomer subunit, monosaccharide (base of carbohydrate). can be linear or in a ring structure, mostly found in ring. Used as an energy source, and structural components.
