Answer to Question #90950 in Biochemistry for Sankalp pathak

Question #90950
. Treatment of a polypeptide by 2-mercaptoethanol yields two polypeptides that have the following amino acid sequences: X: Ala-Phe-Cys-Met-Tyr-Cys-Leu-Trp-Cys-Asn Y: Val-Cys-Trp-Val-Ile-Phe-Gly-Cys-Lys Chymotrypsin-catalyzed hydrolysis of the intact polypeptide yields polypeptide fragments with the following amino acid compositions: (Ala, Phe) (Asn, Cys2, Met,Tyr) (Cys, Gly, Lys) (Cys2, Leu,Trp2,Val) (Ile, Phe,Val) Indicate the positions of the disulfide bonds in the original polypeptide. Cysteines are numbered in order (C1, C2, C3 in X; and C4, C5 in Y).
