Document Summary
Lecture #3: organic chemistry- the study of carbon compounds. A. organic compounds- c bonded to c or h: the study of carbon compounds- the chemistry of life, cell is 70%-90% water and the rest is carbon based compounds. A. organic molecules of only c and h: example: methane (ch4). Iii. concept 5. 1: macromolecules are polymers built from monomers. A. macromolecules: macromolecules are large molecules formed by thousands of atoms. B. four classes found in cells: carbohydrates, proteins, lipids, nucleic acids. A. made of c, h, and o: approximate ratio of ch2o. B. monomers are sugars: 3-7 carbons, hydroxyl groups, and carbonyl group, very hydrophilic. C. sugars" names tend to end in -ose : example: glucose. G. carbohydrate summary: made of c,h, and o, monomers = sugars, for storage and structure. Concept 5. 3: lipids are diverse and hydrophobic (not polymers) A. lipids are hydrophobic: do not dissolve in water, dissolve in nonpolar solvents, for examples, chlorofoam and soap, three important lipid families, fats, phospholipids, steroids.
