Document Summary
Carbon-based compounds = organic compounds (contain carbon bonded to another carbon or hydrogen) Tetravalent carbon = carbon with 4 single valence e- (4 bonds) When a molecule gives up a hydrogen, it is negatively charged. 3 out of 4 biological molecules are polymers or monomers. Lipids are biological molecules but they are not polymers or monomers. Utilize enzymes to remove water = forms a polymer. Utilize enzymes to add water = breaks to monomers. Function is to fuel for cellular work and serve for synthesis of other types of small organic molecules. Ring formed in 2 ways = a or b glucose. Glycosidic linkage = the covalent bond between monosaccharides. Dehydration synthesis = adds more fatty acids = result in ester linkage. Solid in room temperature missing hydrogen liquid in room temperature. One side of saturated fat and one side of unsaturated fat. Polymer = protein or polypeptide (lot of amino acid group together)
