Question

1. What is the product is the product formed from the acid hydrolysis of a simple amide? a. acid & base b. aldehyde & alcohol c. acid & amine d. ester & alcohol e. amine & aldehyde B. . Insulin is a polypeptide hormone that contains two short polypeptide chains linked by two interstrand disulfide bonds. The most login he most logical order of events to perform in order to sequence this protein would be: The peptides are reduced with mercaptoethanol. The peptides are sequenced using Edman chemistry. The peptides are separated by chromatography techniques. a. A,C,B b. C, A, B c. C.BA d. A,B,C e. B,C,D is specific in hydrolyzing only peptide bonds in which the carboxyl function is contributed by an arginine or a lysine residue. a. Chymotrypsin b. Carboxypeptidase c. Trypsin d. CNBr e. None of the above. 4. In the SDS-PAGE (sodium dodecylsulfate - polyacrylamide gel electrophoresis) method, separation takes place on the basis of a. charge only, because all particles have different charges, but the same mass. b. the sieving action of the gel, because all particles have the same charge, but different masses. c. the sieving action of the gel, because all particles have approximately the same charge/mass ratio, but different masses. d. the chemical nature of the buffer used as the electrolyte. 5. If a protein with the sequence PQRKYPIG is treated with trypsin, what will the products be? a. PQR KYPIG b. PORK YPIG c. PQR K YPIG d. PQ R KPIGO following groups is not present in a phosphatidic acid?
