as 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 e 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.

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 positions of glycine and serine should be reversed The alpha carbon of serine is missing a proton The carbon next to the peptide bond should be connected to oxygen via a double bond as opposed to hydrogen via a single bond a negative charge should be added to the C terminus
