Concept explainers
a.
To identify:
The N and C terminus of the given peptides Ala-Asn-Thr.
Introduction:
The condensation reaction between the N-terminal of one amino acid and carboxylic group of another amino acid leads to the formation of a peptide bond. According to the convention, N-terminal of amino acid in a peptide bond is written on the left hand side while the C-terminal of amino acids is written on the right hand side.
The N-terminus represents the starting of the polypeptide which refers the free amino group and the C-terminus represents the end of the polypeptide which refers the free carboxyl group.
b.
To identify:
The N and C terminus of the given peptides DS.
Introduction:
The condensation reaction between the N-terminal of one amino acid and carboxylic group of another amino acid leads to the formation of a peptide bond. According to the convention, N-terminal of amino acid in a peptide bond is written on the left hand side while the C-terminal of amino acids is written on the right hand side.
The N-terminus represents the starting of the polypeptide which refers the free amino group and the C-terminus represents the end of the polypeptide which refers the free carboxyl group.
c.
To identify:
The structural formula for the given peptide Val-Arg.
Introduction:
The condensation reaction between the N-terminal of one amino acid and carboxylic group of another amino acid leads to the formation of a peptide bond.

Draw and label all possible isomers for [M(py)3(DMSO)2(CI)] (py = pyridine, DMSO dimethylsulfoxide).arrow_forwardThe emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes. Instrumental data…arrow_forward
