10/2/2007 2 The Carbon Atom Carbon also makes strong bonds with hydrogen, oxygen, nitrogen, sulfur, and the halogens H O C H H H H C H NH 2 Cl C H H H C Cl Cl Cl Bonds to non-hydrogen atoms define different functional groups. Functional Groups; Hydrocarbons CC H H H H H H Alkane – only carbon-carbon single bonds General formula C n H 2n+2 H H H H Alkene – at least one carbon-carbon double bond General formula C n H 2n H H Alkyne – at least one carbon-carbon triple bond General formula C n H 2n-2

10/2/2007 3 Hydrocarbons Saturated: a hydrocarbon that contains the maximum number of hydrogen atoms possible and that contain only single covalent bonds Unsaturated: a hydrocarbon in which hydrogen atoms can be added CC H H H H + H 2 H H H H H H unsaturated saturated Fats and Oils Saturated fat: fatty acid with no double bonds in the carbon chain O Foods that contain a high proportion of saturated fat are butter, coconut oil, cottenseed oil, dairy products (especially cream and cheese) and meat OH More often solid at room temperature and have longer shelf lives Numerous studies have suggested that diets high in saturated fats increase risk of heart disease and stroke
