Lecture Five 9/3/10 Organic Molecules - complex molecules containing a carbon-carbon bond. Composed largely of Carbon, Hydrogen, Oxygen and Nitrogen. (S,P) Functional groups - there are about eight functional groups. Groups of atoms attached to the carbon backbone of organic molecules. Cause changes in physical characteristics and chemical properties. Hydroxyl- -OH (polar functional group) great possibility it will go into solution. Carbonyl- -C=O (polar functional group) also possibility of going into solution. Ketone - located inside carbon chain. Aldehyde - located on the end of the carbon chain. Carboxyl- HO-C=O (polar functional group) they dissociate. They are acidic. Ex- amino acids. They are polar. (they produce hydrogen ions) Amino- H-N-H (polar functional group) also in amino acids. Phosphate- O | O=P-OH | OH (polar functional group) they dissociate, and are also acidic. Sulfhydryl-
