7620764817Hydroxyl: Structure0
7620764818Hydroxyl: Name of CompoundAlcohols (their specific names usually end in -ol)1
7620764819Hydroxyl: ExampleEthanol2
7620764820Hydroxyl:Functional Properties-Is Polar as a result of the electrons spending more time near the electronegative oxygen atom -Can form hydrogen bonds with water molecules, helping dissolve organic compounds such as sugars3
7620764821Carbonyl: Structure4
7620764822Carbonyl: Name of CompoundKetones: if the carbonyl group is within a carbon skeleton Aldehydes: if the carbonyl group is at the end of the carbon skeleton5
7620764823Carbonyl: ExampleAcetone (a ketone) Propanal (a aldehyde)6
7620764824Carbonyl: Functional Properties-A ketone and an aldehyde may be structural isomers with different properties (like acetone & propanal) -These two groups are also found in sugars, giving rise to two major groups of sugars: aldoses (containing aldehyde) & ketoses (containing a ketone)7
7620764825Carboxyl: Structure8
7620764826Carboxyl: Name of CompoundCarboxylic Acids (or organic acids)9
7620764827Carboxyl: ExampleAcetic Acid10
7620764828Carboxyl: Funcational Properties-Has acidic properties (source of hydrogen ions) because the covalent bond between oxygen and hydrogen is so polar (H leaves the OH) -Found in cells in the ionized form with a charge of 1- and called a carboxylate ion (here, specifically, the acetate ion)11
7620764829Amino: Structure12
7620764830Amino: Name of CompoundAmines13
7620764831Amino: ExampleGlycine14
7620764832Amino: Functional Properties-Acts as a base; can pick up an H+ from the surrounding solution (water, in living organisms) -Ionized, with a charge of 1+, under cellular conditions15
7620764833Sulfhydryl: Structure16
7620764834Sulfhydryl: Name of CompoundsThiols17
7620764835Sulfhydryl: ExampleCysteine18
7620764836Sulfhydryl: Functional Properties-Two sulfhydryl groups can react, forming a covalent bond. This "cross-linking" helps stabilize protein structure -Cross-linking of cysteines in hair proteins maintains the curliness or straightness of hair. Straight hair can be "permanently" curled by shaping it around curlers, then breaking and re-forming the cross-linking bonds19
7620764837Phosphate: Structure20
7620764838Phosphate: Name of StructureOrganic phosphates21
7620764839Phosphate: ExampleGlycerol phosphate22
7620764840Phosphate: Functional Properties-Contributes negative charge to the molecule of which it is a part (2-- when at the end of a molecule; 1-- when located internally in a chain of phosphates) -Has the potential to react with water, releasing energy23
7620764841Methyl: Structure24
7620764842Methyl: Name of CompoundMethylated compounds25
7620764843Methyl: Example2-methylhexane26
7620764844Methyl: Functional Properties-Addition of a methyl group to DNA, or to molecules bound to DNA, affects expression of genes -Arrangement of methyl groups in male and female sex hormones affects their shape and function27
