Term
Hydroxyl
Definition

[image] 

Properties: known as an ALCOHOL; increase solubility and hydrophilicity

Term
Carbonyl
Definition

[image]  

Properties: double bond to oxygen; ketone or aldehyde, depending on structure; increases polarity and therefore solubility

Term
Carboxyl
Definition

[image] 

Properties: hydroxyl group and carbonyl group; proton donor, therefore acidic at Cellular pH; polar, therefore soluble in water; hydroxyl group and carbonyl group;

Term
Amino
Definition

[image]

Properties: base; nitrogen has lone pair; 

Term
Sulfhydryl
Definition

[image]

Properties: AKA Thiol or mercaptan; slightly hydrophilic (not enough to make a large difference); analogous to hydroxyl group though less polar

Term
Phosphoryl
Definition

[image]

Properties: AKA organic phosphate; when separated completely it is known as an inorganic phosphate; at cellular pH is is acidic (donates all Hs);

Term
Methyl
Definition

[image]

Properties: common; nonpolar;
