Properties of water
2 hydrogen bonds covalently bonded to oxygen
Properties of hydrogen bonding
high specific heat
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
Carbohydrates
polymers of sugar; backbone of DNA & RNA
Lipids
fats (saturated & unsaturated), phospholipids, steroids, and waxes
Saturated fat
clogs arteries; no double bonds in their hydrocarbon tail; solid at room temp
Unsaturated fats
double bond in their hydrocarbon tail; liquid at room temp
Phospholipids
lipids w/ a phosphate group
steroids
lipids; precursor to hormones and drugs
Proteins
composed of amino acids, enzymes are proteins that act as catalysts
Fundamental unit of biology
cell
Prokaryotic cells
cell wall & cytoplasm; no defined nucleus (nucleoid)
Eukaryotic cells
