A 1.00-mg sample of a pure protein yielded on hydrolysis 0.0165 mg of leucine and 0.0248 mg of isoleucine. What is the minimum possible molar mass of the protein? (MMleucine=MMisoleucine=131g/mol)
On complete hydrolysis, a polypeptide gives two alanine, one leucine, one methionine, one phenylalanine, and one valine residue. Partial hydrolysis gives the following fragments: Ala-Phe, Leu-Met, Val-Ala, Phe-Leu. It is known that the first amino acid in the sequence is valine and the last one is methionine.

4: Draw structures from notations or notations from structures, for the following dipeptides. Look up in book for the structures of various amino acids and their names (and notations). (EOCQ 60) Hints for drawing a dipeptide from the specified amino acids. From the given symbols (Ser, Thr, etc), draw the structures for the amino acids in the specified order example, for Ser-Thr, draw Serine first and then Threonine). Then remove the OH from the first amin and one H (from the N atom) on the second amino acid. Then join the remaining fragments; that give the dipeptide formed. In these reactions, H2O is formed as a side product; but it is implied, and you have to show it in your answers. The following equation illustrates that. Here, R and R' are symbolic. In an actual question, you must the actual structures for the amino acids (Table 16.3 in the book). O H || | Н.N— CH— С-N-CH—С-ОН H,N-CH-C–OH + H,N-CH-Ċ–OH R' R.
