Chapter 4 – Carbon I. Carbon – the main component in most biological molecules A. Carbon enters the bioshere through photosynthesis B. Animals acquire carbon from plants or from other animals C. The properties of Carbon provide the basis for molecular and, therefore, biological diversity D. All known life is tied to the chemical nature of the carbon atom II. Organic Chemistry is the study of Carbon A. Carbon based molecules exist from the very simplest (methane with one carbon atom and 4 hydrogen atoms) to extremely large proteins and nucleic acids with molecular weights into the hundreds of thousands B. The overall percentage of C, H, O, N, S, and P are the same in any given organism but there is great diversity in the qualitative aspects of how these atoms are arranged C.
