carbohydrates
lipids
proteins
nucliec acids - 2organic chemistrythe study of carbon compounds
- 3carbon atomsbonding properties
4 stable covalent bonds - 4properties of hydrocarbonscarbon & hydrogen
non - polar
hydrophobic
stable
little attraction between bonds
gases at room temperature - 5ethane vs. ethanolethane:
hydrogen
non polar
gas
ethanol:
hydroxyl group
polar
liquid - 6functional groupsparts of organic molecules that are involved in chemical reactions and male hydrocarbons hydrophilic
Ex. hydroxyl
amino
carbonyl
sulhydryl
carboxyl
phosphate - 7male and female carbon compoundsbasic structure is identical but they interact with different functional groups
different functional groups
HO - estradiol
CH3 - testosterone - 8hydroxylOH
alcohols
Ex. ethanol - 9carbonylC=O
if C=O at end: aldehyde
if C=O in middle: ketone - 10carboxylCOOH
C double bonded to O and single bonded to OH group
compounds with COOH = acids
Ex. fatty acids, amino acids - 11aminoNH2
compounds with NH2 = amines
amino acts as a base
