Chapter 4: Organic Chemistry (carbon) Importance of Carbon Functional Groups

What is Valence?

Hydrocarbons

Try to sketch: C3H8O propanol C2H4 ethene Hydrocarbons = contain only the elements H and C, non-polar, do not react with water, hydrophobic, like fatty acids

Isomers

Enantiomers

Functional Groups -OH Hydroxide alcohols; polar group -COOH Carboxyl carboxylic acids (release H+) -SH Sulfhydryl thiols, see cysteine amino acid, cross links stabilize protein structure. (see Ch.5)

Functional Groups -NH2 Amino amines, can act as bases (NH3), accept H+ -PO4 Phosphate anion (-OPO3-2); used in energy transfers -C=O Carbonyl (aldehyde or ketone); polar group -CH3 Hydrocarbons, non polar, hydrophobic regions of a molecule
