Document Summary
Atom molecule macromolecules organelle cell tissue organ organ system organism. Substituent group added to a carbon chain. Geometric isomers: orientation of atoms about a double. Enantiomers: molecules that are mirror images of each other not superimposable (important with the enzymes) Polar (electronegativity difference 0. 5 1. 7) vs nonpolar (0. 0 can form up to 4 bons. Isotopes: same number of protons, different number of neutrons (radioactive) Cohesion (can have intermolecular force and hold itself together) and adhesion (can attract to surfaces like glue) In order for water to boil, you have to break the hydrogen bonds. Low density of ice (less dense than its liquid form) Buffers: mixture of weak acid and conjugate based that. Ph scale: the lower the ph, the higher the acidity ( can have. Carbohydrates formed through a condensation reaction removal of h from one molecule and oh from another (creates water) Molecules used in biology for energy storage orstrucutual component (e. g. starch and cellulose)
