please help!!! 19. A peptide is composed of the following amino acids: Ala, Arg. Glu, Gly, Lys, Met, Phe, Ser, Tyn Given the following data deduce the sequence of the peptide. Trypsin digestion yielded two fragments with the following composition: Fragment 1: Ala, Arg, Glu, Met, Phe, Ser Fragment 2: Gly, Lys, Tyr Chymotrypsin digestion yielded three fragments with the listed compositions: Fragment 1: Ala, Gly, Lys, Phe Fragment 3: Arg, Glu, Met, Ser Cyanogen Bromide cleavage yielded two fragments...
1.) Draw the structure of the amino acid Serine(ser), which has R=-CH2-OH. Label the alpha carbon. 2.) Draw the dipeptide that forms between serine and alanine. The dipeptide sequence is Ser-Ala. Label the peptide bond. 3.) How many amino acids residues are in a polypeptide containing 6 peptide bonds? How many peptide bonds are in a tripeptide 4.) Sketch a alpha-helix and a beta-sheet as best as you can. Label each.
Explain this question please! Name (4 ofer to the Table of Amino Acids at the beginning of the exam to help solve this problem. Polypeptide I is a 12-mer and has the following amino acid composition: Ala, Arg, 2 His, Leu, 2 Lys, 2 Phe, Ser, Thr, Trp Edman degradation of I shows that its N-terminal amino acid is His. Chymotrypsin cleavage of I yields peptide fragments A-D.Trypsin cleavage of I gives peptide fragments E-G. Shown below is the amino...
