POLAR COVALENT BONDS
-
Polar covalent bond- when an atom is bonded to a more electronegative atom, the electrons of the bond are not shared equally
-
HYDROGEN BONDS
Hydrogen bond- weak attractions between oppositely charged regions of water molecules. Allows water molecules to bond to each other

ORGANIC CHEMISTRY
-
Atoms of hydrogen are attached to the carbon skeletons wherever electrons are available for covalent bonding
Stanley Miller Experiment- designed an experiment on the abiotic (nonliving) synthesis of organic compounds to investigate the origin of life
-
Chemical group
Methyl groups - Non-polar, hydrophobic, turns genes off. Examples: Fatty acids, oils, and waxes
Amino groups- Polar, weak base, hydrophilic
Carboxyl groups- Polar, hydrophilic
Hydroxyl groups- Polar, Hydrophilic, found in sugars
