PPT-Chapter 4: Life is based on molecules with carbon (organic

organic compounds isomers functional groups Much of the chemistry of life is based on organic compounds organic compounds have at least one carbon atom covalently bound to either another carbon atom.

Scientific: How could life originate?. Biochemistry. Objectives. SWBAT describe the bonding properties of carbon atoms.. SWBAT compare carbohydrates, lipids, proteins, and nucleic acids.. Starter. We have talked about carbon based molecules in other units. I want you to take a couple of minutes and make a list of the carbon based compounds we have touched on in this class or you have heard about in other places.. Ultimate . question . for biologists.

Lecture Presentation by . Nicole . Tunbridge. and. Kathleen Fitzpatrick. Carbon: The Backbone of Life. Living organisms consist mostly of carbon-based compounds. Carbon is unparalleled in its ability to form large, complex, and varied molecules. 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. Carbon-based molecules are the foundation of life.. Bonding Properties of Carbon. Carbon forms covalent bonds with up to four. . other atoms, including other carbon atoms.. 1. 2. 3, 4.
