THE periodic acid Schiff technique has been used histochemically primarily as a means of localizing the 1,2 glycol linkage in tissue sections 1. It is known, however, that periodic acid is also ...

Since these side-reactions may lead to complications in investigations on the separation and determination of dinitrophenyl amino-acids in general, it seems useful to communicate these facts briefly.

We have made this method quantitative for α-alanine, which gives acetaldehyde1. The ninhydrine reaction can also be applied to the quantitative determination of certain other amino-acids.

After their success using cyanide to drive other chemical reactions, Krishnamurthy and his colleagues suspected that cyanide, even without enzymes, might also help turn α-keto acids into amino acids.

Indeed, methods that modify the amino acids cysteine or lysine through linkages made by acid–base reactions are readily available.
