Chapter 9, Problem 21P
Interpretation Introduction

Interpretation:

The structure of the acetylenic amino acid, which, on catalytic hydrogenation yields homoleucine as the only product whose structure is provided, is to be determined.

Concept introduction:

Hydrogenation of alkynes in the presence of the customary metal catalysts

consumes two molar equivalents of H2 to give alkanes.

Carboxylate group is not reduced in this reaction.

During hydrogenation, two hydrogen atoms get attached to each triple bonded carbon atom in the alkyne.

The triply bonded carbon atoms in an alkyne group are bonded to only one other atom.

An unknown acetylenic amino acid obtained from the seed of a tropical fruit has the molecular formula C7H11NO2. On catalytic hydrogenation over platinum, this amino acid yielded homoleucine (an amino acid of known structure shown here) as the only product. What is the structure of the unknown amino acid?
During the hydrolysis of proteins, some amino acids, such as tryptophan, do not survive the reaction conditions. Other amino acids, such as asparagine and glutamine, are modified. Referring to Table 1-7 (p. 39), which shows the structures of the 20 common amino acids, write the structures of the two amino acids that are formed when asparagine and glutamine decompose in hot, concentrated HCl.
Use the following pentapeptide (5 amino acids linked together) structure and draw it again with the following amino acid sequence: glutamine, glycine, serine, alanine threonine. (Hint: You will have to look up the atoms that make up the R groups of the amino acids to replace the generic "R" in the structural formula provided).
