Unformatted text preview: Carbon and the Molecular Diversity of Life Carbon Compounds + Life chapter 3 . A compound containing carbon is an ORGANIC COMPOUND . 4 main classes of molecules: carbohydrates , proteins, + nucleic acids + lipids Carbohydrates , proteins , + nucleic acids are huge and Known as MACROMOLECULES.` 4 other atoms can form diverse molecules by bonding to " the key to an atoms chemical characteristics is its electron configuration The formation of Bonds with Carbon . the shape of a molecule often determines its function The 4 major atomic components of organic molecules is H, O, + N bonded to Carbon The # of unpaired electrons in the valence shell of an atom is generally equal to the atoms VALENCE or the # of covalent bonds it can form Molecular Diversity Arising from Variation in Carbon Skeletons . carbon chains form the skeletons of most organic molecules . The organic molecules consisting of only I carbon + hydrogen are called HYDROCARBONS . they can undergo reactions that release a large amount of energy The Chemical Groups Most Important to Life . the # and arrangement of chemical groups help give each organic molecule its unique properties. . The chemical groups affect molecular function by being directly involved in the reaction are FUNCTIONAL GROUPS . The 7 chemical groups that are most Important arc :" hy droxl , carbonyl , carboxyl, amino, sulfhy dry!, phosphate, methyl ATP : An important source of energy for cellular Processes . a complicated organic phosphate : ADENOSINE TRIPHOSPHATE (ATP) " it's storing the potential to react with water . The reaction releases energy that can be used by the cell...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
