5036845492inorganic moleculesopposite of organic molecules but they can also play important role in living things ( liek salts :)1
5036853576single bondsharing 1 electron in a covelant bond2
5036856206double bondsharing 2 electrons3
5036860003triple bondsharing 3 electrons4
5036867513polar moleculesattracted to water molecules; hydrophilic5
5036872976nonpolar moleculesinsoluble w/ water and repell it; hydrophobic6
5036892755isomersmolecules with identical formulas but differ in arrangement of atoms7
5036906157monosaccharides, glycerol, fatty acid, amino acid, nucleotidessmall organic molecules that can serve as monomers (subunit of polymers)8
5036912218polymerlarge macromolecules9
5036918299the four classes of polymers:carbohydrates (polysaccharides), lipids (triglycerides), protiens (polypeptides), and nucleic acids ( RNA & DNA)10
5036942261monosaccharidessimple sugars with carbon backbone of 3 - 7 carbon atoms11
5036956565hydrolysis reactionsbreaks down polymers; a hydroxl group attaches to one monomer and hydrogen attaches to another12
