Presentation Transcript
slide1
-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
slide2
-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
slide3
-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

slide4
-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
slide5
-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
slide6
-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
