  The present invention herein provides a combination of stable isotope-labeled aliphatic amino acids, which permits the structural analysis of a high molecular weight protein, in particular, a high molecular weight protein whose molecular weight exceeds 60 kDa. This is a combination of stable isotope-labeled amino acids which is characterized in that arginine (Arg), glutamine (Gln), glutamic acid (Glu), lysine (Lys), methionine (Met) and proline (Pro) satisfy the following requirements concerning the labelling pattern: (b) one of the methylene hydrogen atoms of at least one of the methylene groups is deuterated and the both of the two methylene hydrogen atoms of at least one of the methylene groups are likewise deuterated; and (d) when they each have a methyl group, the hydrogen atoms of the methyl group except for one of the same are deuterated, or the methyl group is completely deuterated.

  [1,2-13C2]ABA, which is designed as a stable and pure internal standard for GC/MS analysis, is synthesized through the Witting reaction of 1-hydroxy-4-keto-α-ionone with carbomethoxymethylenetriphenylphosphorane prepared from [1,2-13C2]bromoacetic acid followed by saponification of the product methyl [1,2-13C2]ABA.
