WGU Biochem Module 2 Amino Acids
Hydrophobic Amino Acids - ANSContain carbon & hydrogen, have non-polar sidechains
Amino Acid structure - ANSContains an amino acid group, carboxyl group, an R group
surrounded by an Alpha carbon
Polar Amino Acids - ANSHave -OH & -NH groups at the end of the R group
Charged Amino Acids - ANSHave a - or + charge at the end of the R group
Disulfide Bonds - ANS"S" means sulfide covalent bond. Very strong Glycine
Amino acid found in the interior of a protein? - ANSHydrophobic Amino Acid
Amino Acid found on the exterior surface of protein? - ANSCharged polar Amino Acid
Primary Structure of Proteins - ANSAmino Acid sequence of polypeptide alpha & beta chains
Secondary structure of protein - ANSConsists of pleated & folded polypeptide chains. Held
together by hydrogen bonds.
Tertiary structure of protein - ANSFolded 3 dimensional shape of polypeptide chain & its
helixes & pleated sheets.
Quaternary structure of protein - ANSWhen 2 or more long polypeptide chains participate in
the final shape of a protein. Ex: Hgb & collagen
Structure of Hgb - ANS2 Alpha chains & 2 Beta chains making 4 subunits
How are peptide bonds formed? - ANSBy a dehydration reaction
How can a peptide bond be broken? - ANSBy hydrolysis
Chaperone - ANSMolecules that help proteins fold properly
