8038954557hydroxyl group: structure—OH : A hyrdrogen atom bonded to an oxygen atom, bonded to the carbon skeleton of the organic molecule0
8038954558hydroxyl group: compound nameAlcohols - names usually end in "-ol"1
8038954559hydroxyl group: compound exampleEthanol, the alcohol present in alcoholic beverages2
8038954560hydroxyl group: functional propertiesPolar ; attracts water molecules, helping to dissolve organic compounds3
8038954561carbonyl group: compound namesketone, if the group is within a carbon skeleton; aldehyde, if the group is at the end of the skeleton4
8038954564carbonyl group: structure>CO : Carbon atom joined to an oxygen atom by a double bond5
8038954565carboxyl group: structure—COOH : Oxygen atom double-bonded to a carbon atom that is also bonded to a hydroxyl group6
8038954566carboxyl group: compound nameCarboxylic acids - organic acids7
8038954567carboxyl group: compound exampleacetic acid, which gives vinegar its sour taste8
8038954568carboxyl group: functional propertiesacidic properties because it can give off hydrogen ions9
8038954569amino group: structure—NH2 : nitrogen atom bonded to two hydrogen atoms and to the carbon skeleton10
8038954570amino group: compound nameAmines11
8038954571amino group: compound exampleamino acids - has carboxyl group as well, thus the name12
8038954572amino group: functional propertiesacts as a base; can pick up a proton (H+ ion) from the surrounding solution; ionized with a charge of 1+ under cellular conditions13
8038954573sulfhydryl group: structure—SH : sulfur atom bonded to an atom of hydrogen (resembles a hydroxyl group in shape)14
8038954576sulfhydryl group: funtional propertiestwo can interact to help stabilize protein structure15
8038954577phosphate group: structure—OPO3: phosphorus atom is bonded to four oxygen atoms; one oxygen is bonded to the carbon skeleton; two oxygens carry negative charges (ionized form of a phosphoric acid group)16
8038954578phosphate group: compound nameOrganic phosphates17
8038954579phosphate group: compound examplefound on nucleic acids18
8038954580phosphate group: functional propertiesmakes the molecule of which it is a part an anion (negatively charged ion); can transfer energy between organic molecules19
