Document Summary
Many of them are biological, but not all by any means. Each element has a one or two letter symbol. A molecule is described by a chemical formula. Shows which kinds of atoms there are and how many. H2o is the formula for water: 2 hydrogen"s + 1 oxygen. C6 h12 o6 is one from of sugar. 6 carbons + 12 hydrogen"s + 6 oxygen"s. Isomers = 2 or 3 or 4 molecules with the same stuff in them but shaped differently. Structural formula provides a 2-d idea of molecules shape. Carbon compounds can have prefixes for number of carbons in a chain. Groups of atoms form functional groups in molecules. Some have single carbon bonds = these are saturated hydrocarbons. Alkenes have double bonds, alynes have triple bonds. Can be a monomer that joins with others to form a polymer. Amino acid molecules have a carboxyl end and an amino group.
