Biochemistry

oils, fats, lipids

• water loving
• polar molecule that dissolves in H2O

• when water is solid, it allows H2O to form hydrogen bonds and spread out
• solids are less dense

what is doing the dissolving

partially negative charged oxygen atoms and the partially positive charged hydrogen atom of a molecule bonds to O, N, F of another molecule

• water fearing
• non polar molecule that do not dissolve in H2O

specific location where the substance bonds on enzyme

atom that has lost or gained one or more electrons becomes and ion and carries an electric charge

pure substance formed when different elements combine

• compactness of a substance
• ratio of mass to volume
• d=m/v

cup shaped form at the top of H2O

tendency of a liquid substance to move along a solid substance due to adhesion.  cohesion also allows H2O to pull H2O along with it

• molecules of a liquid stick together
• hydrogen bonds cause this with H2O
• H2O strider stands of surface of H2O

• molecule without an electical charge
• do not dissolve in H2O
• ex- lipids

• unequal distribution of charges on the water molecule make it a polar molecule
• H2O molecule has a positive and negative end
