Properties of Water 2 Hydrogen bonds Covalently bonded to Oxygen. Hydrogen Bonding between molecules. - High specific heat - Large bodies or water stabilize climates - Strong cohesive and adhesive properties - Water freezes forms a lattice crystal resulting in ice floating in water.- Polarity of water allows it to act as a universal solvent. - Water can be used to dissolve different solvents. Carbohydrates Long chains, or polymers of sugar. Most importantly form the backbone of DNA and RNA. Saturated Clogs arteries. NO DOUBLE BONDS in their hydrocarbon tail. SOLID @ room temperature. Unsaturated Double bond in their hydrocarbon tail. LIQUID at room temperature. Phospholipids Phosphate group (polar) soluble in water. Hydrocarbon tail of fatty acids is nonpolar and nonsoluble in water. Ex. Cell Membrane Steroids Are lipids, which are precursors to hormones and drugs Proteins They are Polymers of 20
