1 Introduction to Biochemistry © 2006: D. Julian Home Page Carbon Molecules © 2006: D. Julian Organic vs. Inorganic Molecules that contain carbon atoms are called “organic molecules”. Because carbon has 4 electrons in a valence shell that could hold 8, it has little tendency to gain or lose electrons, and instead tends to form covalent bonds with up to 4 other atoms. © 2006: D. Julian

2 Space-filling model of a protein © 2006: D. Julian Shapes of simple organic molecules Four hydrogens can complete the valence shell of one carbon. A carbon can also form single bonds with another carbon… or even double bonds with another carbon. © 2006: D. Julian Campbel and Reece, Figure 4.3 Carbon skeletons The diversity of carbon “backbones” produce molecules with different chemical properties, even when the only other atom is hydrogen. © 2006: D. Julian Campbel and Reece, Figure 4.5
