THE CHEMISTRY OF CARBON
• Organic Chemistry• The study of all compounds that contain bonds
between carbon atoms
• Carbon• 4 valence electrons
• Forms strong covalent bonds with H, O, P, S, N• Can bond to other carbon atoms
• Ability to form chains of almost unlimited length• Can form rings

MACROMOLECULES
• Giant molecules
• Made from many smaller molecules
• Formed through polymerization• Small compounds are joined together to form larger
compounds• Smaller units: monomers• Larger units: polymers
• Four groups in living things• Carbohydrates• Lipids• Proteins• Nucleic acids

DEHYDRATION SYNTHESIS
• Polymerization reaction where monomers are joined together to form polymers by removing water molecules

HYDROLYSIS
• Process of splitting a polymer into monomers with the addition of water molecules

CARBOHYDRATES
• Made of C, H, and O (1:2:1)
• Uses• Main source of energy in living things• Structure
• Monomer: monosaccharides (single sugar molecules)• Glucose
• Polymer: polysaccharides• Starch, glycogen, cellulose

LIPIDS
• Made of mostly C and H
• Not soluble in water
• Fats, oils, waxes
• Uses• Store energy• Biological membranes• Waterproof coverings• Chemical messengers
• Subunits• Fatty acids combine with glycerol

LIPIDS
• Saturated• Each carbon atom in a lipid’s fatty acid chain is joined
to another carbon by a single bond• Contains the maximum number of hydrogen atoms
• Unsaturated• There is at least one carbon-carbon double bond in a
fatty acid
• Polyunsaturated• Contain more than one double bond

PROTEINS
• Contain C, H, O, and N
• Polymers of amino acids• Compounds with an amino group at one end and a
carboxyl group on the other end• More than 20 different amino acids are found in nature• Roles
• Control the rates of reactions• Regulate cell processes• Form bones and muscles• Transport substances into or out of cells• Help fight disease

PROTEINS
• Four levels of organization

NUCLEIC ACIDS
• Contain C, H, O, N and P
• Monomers: nucleotides• 3 parts
• A 5-carbon sugar• A phosphate group• A nitrogenous base
• Role• Store and transmit genetic information
• 2 kinds• DNA: deoxyribonucleic acid• RNA: ribonucleic acid
