-OH

1. -OH • Name of Functional group: This is a hydroxyl • Function of the group: Draws electrons • Attracts water, Dissolves organic materials such as sugar • Polar or non-polar: Polar • Hydrophobic or hydrophilic: Hydrophilic • Found in All Proteins: No • Found in Many Proteins: Yes • Found in Lipids: No

2. -CO2 • Name of Functional Group: This is Carbonyl • Function of the group: structural isomers in a carbon skeleton • Polar or non-polar: non-polar • Hydrophobic or Hydrophilic: hydrophilic • Found in all Proteins: Yes • Found in many Proteins: No • Found in Lipids: Yes

3. -COOH • Name of Functional Group:This is carboxyl • Function of the group:Has acidic properties because it is a source of hydrogen ions • Polar or non-polar:The covalent bond between oxygen and hydrogen is so polar that hydrogen ion tend to dissociate reversible • Hydrophobic or Hydrophilic: Hydrophilic • Found in all Proteins: Yes • Found in many Proteins: No • Found in Lipids: No • http://youtu.be/mAjrnZ-znkY

4. -NH2 • Name of functional group: This is an Amino group • Function of the group: Acts as a base; can pick up a proton from another solution. Ionized, with a charge of 1+. • Polar or nonpolar: Polar • Hydrophobic or Hydrophilic: hydrophilic • Found in all Proteins: Yes • Found in many Proteins: No • Found in Lipids: No

5. -SH • Name of the Functional Group: This is the Sulfhydryl group • Function of the group: two of these can interact to help stabilize protein structure. • Polar or nonpolar: since the electronegativity difference is so small, it is nonpolar • Hydrophobic or hydrophilic: hydrophilic • Found in all Proteins: No • Found in many Proteins: Yes • Found in Lipids: No

6. -PO4 • Name of Functional group: This is Phosphate • Function of the group: Transfers energy between organic molecules • Polar or non-polar: non polar • Hydrophobic or Hydrophilic: hydrophilic • Found in all Proteins: No • Found in many Proteins: No • Found in Lipids: Yes
