BILD 1 Chapter 4 C,H,O,N,S and P are major elements of life THE FORMATION OF BONDS WITH CARBON -Carbon completes its 4 valence by sharing electrons- tetravalence -CO2 is the source of carbon for all the organic molecules found in organisms HYDROCARBONS -Does not dissolve in water- are hydrophobic -Great majority of their bonds are non-polar carbon to H linkages **Undergo reactions that release a relatively large amt of energy ISOMERS Structural Isomers - differ in the covalent arrangements of their atoms -may also differ in the location of double bonds Geometric Isomers - have same covalent partnerships but they differ in their spatial arrangements -may be due to the inflexibility of double bonds

Unformatted text preview: -Cis and Trans Enantiomers- molecules that are mirror images of each other-has 4 different groups attached to center C-Usually one enantiomer is biologically active and other inactive FUNCTIONAL GROUPS-The components of organic molecules that are most commonly involved in chemical reactions Most inportant biological functional groups-hydroxyl-carbonyl-carboxyl-amino-sulfydryl-phosphate **They are all hydrophillic and increase the solubility of organic cmpds in water ATP-adenosine triphosphate-Adenosine and 3 phosphate groups-Loses 1 phosphate and becomes ADP- adenosine diphosphate...
