Chapter 4 – Carbon and the Molecular Diversity of Life Overview: Carbon: The Backbone of Life Living organisms consist mostly of carbon-based compounds - Carbon is unparalleled in its ability to form large, complex, and diverse molecules Proteins, DNA, Carbohydrates , and other molecules that distinguish living matter are all composed of carbon compounds Concept 4.1: Organic chemistry is the study of carbon compounds Organic Chemistry is the study of compounds that contain carbon - Organic compounds range from simple molecules to colossal ones Most organic compounds contain hydrogen atoms in addition to carbon atoms Vitalism , the idea that organic compounds arise only in organisms, was disproved when chemists synthesized these compounds Mechanism is the view that all natural phenomena are governed by physical and chemical laws Organic Molecules and the Origin of Life on Earth Stanley Miller’s classic experiment demonstrated the abiotic synthesis of organic compounds - Experiments support the idea that Abiotic ( Without ) of organic compounds, perhaps near volcanoes, could have been a stage in the origin of life Figure 4.2 Concept 4.2: Carbon atoms can form diverse molecules by bonding to four other atoms
