Chapter 3 – The Chemistry of Life: Organic Compounds Since a small change in the pH of a cell can kill the cell what causes most human cells to prefer a slightly basic matrix of about 7.4? What is the pathway that a mis-folded protein takes when in the process of being degraded? Look over page 46 Fig. 3-1 I) Organic Compounds a. Isomers i. Structural isomers 1. Differ in the covalent arrangement of their atoms, and often properties due to functional groups ii. Geometric (stereo) isomers [cis-trans] 1. Have identical covalent bonds but differ in the order in which groups are arranged in space, but properties are usually the same 2. Enantiomors a. Mirror images of one another II) Hydrocarbons a. Organic compounds i. Carbon and hydrogen ii. Hydrophobic iii. Properties are a result of their functional groups b. Non-Polar i. Methyl Group ii. R-CH 3 iii. Very non-reactive c. Polar Groups i. Polar groups are hydrophilic III)Acids and Basic Groups

a. Basic i. Accepts a hydrogen ion ii. Becomes positively charged 1. Amino group b. Acidic i. Releases hydrogen ions ii. Becomes negatively charged 1. Carboxyl and phosphate groups c. Look over page 49 Table 3-1b IV)Polymers and Macromolecules a. Polymers i. Long chains of linked monomers ii. Linked through condensation reactions b. Macromolecules i. Large polymers ii. Polysaccharides, proteins, DNA iii. Broken down by hydrolysis V) Condensation and Hydrolysis Reactions a. Condensation reactions i. As monomers are added, water molecules are released therefore also called dehydration synthesis
