BASIC CHEMICAL REACTIONS : A. DECOMPOSITION: 2CuO ---> 2Cu + O 2 B. SYNTHESIS: H 2 + O 2 ----> H 2 O C. DISPLACEMENT: Zn + HCl ---> ZnCl 2 + H 2 ORGANIC VS. INORGANIC MOLECULES: CH 4 = SMALL ORGANIC MOLECULE ; NaCl or H 2 O = inorganic Carbon found in living organisms so compounds uniquely found in living things termed organic. They were first thought special = could not be found or created outside of life. Wohler synthesized urea in the early 19 th century. Now we are making DNA and proteins, the most complex of the organic molecules. We can even make viruses. IMPORTANT BIOLOGICAL MOLECULES : 1. Carbohydrates -- draw glucose, explain hydroxyl group and significance of them (hydrogen bonding). Show straight line and ring structure. Explain monosaccharide, disaccharide, polysaccharide. Hexose, Pentose, Trios. We will work with Glucose, Sucrose, and Lactose in the Lab. Polysaccharides structural---

Unformatted text preview: wood---mucopolysaccharides---slime and mucous-- and as energy sources in certain bacteria (fermentative bacteria). Also chitin. Monomers = Single units examples, glucose and fructose= hexoses Another monomer = ribose, deoxyribose = monomers but pentoses Structure of Bacteria: Chemicals have properties. Biochemicals have both properties and ways of interacting with other chemicals eg. Fats vs. Carbohydrates. Fats form monolayers in water. Cell parts and Cells are the basic unit of life. They have attributes: Reproduction, metabolism, storage, transport, movement. We will look at a Prokaryotic cell from the outside in with an eye toward relating cell part properties to the biochemicals which compose them....

    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.
