Use the Data Booklet to sketch the structure of the tripeptide Ala-Ser-Gly, with all peptide bonds drawn in full.
Calculate the relative molecular mass, $M_r$, of Ala-Ser-Gly.
Electrophoresis is a method for separating mixtures of amino acids and peptides. A sample containing the tripeptide Ala-Ser-Gly and its three constituent amino acids was run by electrophoresis in a buffer at $\text{pH }11$. Draw the structure of serine at $\text{pH }11$.
