Please draw the titration curve Arginine (y-axis: pH, x-axis: moles of OH-). Label the graph with the pKas and pI of the amino acid. Also, draw the species of the Arginine along the titration.
A student was asked to draw the structure of the amino acids serine (R group is -CH₂OH) and glycine (R group is -H) linked by a peptide bond. The student was asked to place glycine at the N terminus and serine at the C terminus, label the peptide bond, and label the N- and C-termini. The student's drawing is shown below. Which of the following errors need to be corrected in the student's drawing? Check all that apply. Don't get overwhelmed by the number of options; just consider them one at a time. H H H peptide bond || N terminus H-N-C-C-N-C-C I | H H H-C-H I O-H C terminus OH The nitrogen flanking the peptide bond should be connected to hydrogen via a single bond as opposed to oxygen via a double bond The positions of the N and C flanking the peptide bond should be swapped the labels on the N and C termini need to be swapped a positive charge should be added to the N terminus The alpha carbon of glycine is missing a proton The peptide bond should be shifted one bond to the right The…
A sample of a peptide of unknown sequence was treated with trypsin; another sample of the same peptide was treated with chymotrypsin. The sequences (N-terminal to C-terminal) of the smaller peptides produced by trypsin digestion were as follows: Trp-Arg-Thr-Gin Ser-Trp-Arg-His-Trp-Ala-Lys Asp-Val-Ala-Ala-Lys Asn-Ser-Asn-Val-Ile-Arg The sequences of the smaller peptides produced by chymotrypsin digestion were as follows: Arg-His-Trp Arg-Thr-Gin Ala-Lys-Asn-Ser-Asn-Val-Ile-Arg-Trp Asp-Val-Ala-Ala-Lys-Ser-Trp The original peptide sequence was: Asp-Val-Ala-Ala-Lys-Ser-Trp-Ala-Lys-Asn-Ser-Asn-Val-Ile-Arg-Trp-Arg-His-Trp-Arg-Thr-Gin Asp-Val-Ala-Ala-Lys-Asn-Ser-Asn-Val-Ile-Arg-Trp-Arg-Thr-Gin-Ser-Trp-Arg-His-Trp-Ala-Lys Trp-Arg-Thr-Gin-Asn-Ser-Asn-Val-Ile-Arg-Ser-Trp-Arg-His-Trp-Ala-Lys-Asp-Val-Ala-Ala-Lys Arg-His-Trp-Arg-Thr-Gln-Ala-Lys-Asn-Ser-Asn-Val-Ile-Arg-Trp-Asp-Val-Ala-Ala-Lys-Ser-Trp Asp-Val-Ala-Ala-Lys-Ser-Trp-Arg-His-Trp-Ala-Lys-Asn-Ser-Asn-Val-Ile-Arg-Trp-Arg-Thr-Gin…
