Lecture Notes for BIO160N Carbon Carbon backbone of life 1. It has a valence of 4, and can make 4 bonds 2. It can form long chains and double bonds 3. Side group diversity Isomer compounds with the same number of atoms that vary in structure Compound molecule that is made of 2 or more elements Organic Compound molecules containing carbon ( C ) Ex) CH4 Natural derived organism from nature Synthetic man made (lab) Naturally derived humans created them for an artificial product Allotrope different physical forms when the element bonds to itself Ex) diamonds, graphite ( all C molecules) Carbon forms covalent bonds generally meaning it shares electrons for stronger bonds Compounds made by ionic bonding are called salts Salts: 1. For an ionic compound the formular represents the ratio of elemetns 2. They do not share electrons 3. Salt is the most important electrolyte in our body 4. Preserves food 5. Our nerves fire using sodium Carbon: 1. There is no limit to the number of atoms in a carbon chain Polysaccharides multiple carbohydrates linked together Fatty Acids long chains of carbon 1. Saturated fatty acid chain that is made of only single bonds 2. Unsaturated fatty acid have double bond/ or bonds Hydrocarbons molecules made only of Carbon and Hydrogen 1. Few in living organisms 2. They release large amounts of energy a. Ex) methane, petroleum, and ethane Petroleum tiny sea plants that dies, sank to the bottom of the ocean, where they were held under large amounts of pressure, where they were left with only the Carbon and Hydrogen Isomers same chemical formula but differ in the structure (way they were put together) 1. Structural have the same chemical formula but require a break in the bond a. Ex) glucose and fructose (C6H12O6) 2. Geometric moving where the side chains are based upon the location of the double bond a. Cis means on the same side of the double bond b. Trans have key side groups on the opposite side of the double bond Retinal visual pigment in the rods that allow detections od photons ( it is a cis isomer, then moves to a trans isomer) Enantiomers isomers that are mirror images 1. They differ in spatial arrangements 2. L and D enantiomers (versions of them) Functional Groups a group of atoms responsible for the characteristic reactions of a particular compound 1. They change the type of reaction
