Hydrocarbons

Organic compounds consisting only of carbon and hydrogen can exist as unreached or branched chains or as rings

Mers

Compounds with the same molecular formulas but different structures and thus different properties

Structural isomers

Are compounds that differ in the covalent arrangements of their atoms

Geometric isomers

Componds that are identical in the arrangement of their covenant bonds but different in arrangement of atoms

Enanitomers

Are isomers that are mirror images of each other

Hydrocarbons

Lack distinct charged regions insoluble in water tend to cluster together

Hydrophobic

Water fearing

Functional groups

Groups of atoms that determine the types of chemical reactions and associations in which the compond participates

Methyl group

Nonpolar hydrocarbon

Hydroxyl group

Polar because of the presence of a strongly electronegative oxygen atom

Carbonyl group

Consists of a carbon atom that has a double covalent bond with an oxygen atom

Aldehyde

Has a carbonyl group positioned at the end of the carbon skeleton

Keytone

Has an internal carbonyl group

Carboxyl group

One end of the molecule us hydrophilic and one is hydrophobic

Phospholipids

Consist of a glycerol molecule attached at one end to two fatty acids

Carotenoid

Insaluble in water classified with lipids

Isoprene units

Consist of five carbon hydro carbon monomers

Retinal

Can be converted to visual pigments

Steroid

Consist of carbon atoms arranged in four attached rings

Proteins

Macromolecules composed of amino acids are the most versatile components

Enzymes

Molecules that accelerate the thousands of different chemical reactions that take place in an organism are proteins
