A paper chromatographic method for identification and estimation of pyrrolidonecarboxylic acid

Analytical Biochemistry, 1967
Abstract A paper chromatographic method is described for identification and semimicro estimation of pyrrolidonecarboxylic acid (PCA). When heated with hydroxylamine, PCA undergoes quantitative conversion to γ-glutamyl hydroxamate, which on treatment with ferric chloride gives a brown spot on a yellow background on paper.

A convenient procedure for the determination of pyrrolidonecarboxylic acid and related compounds

Analytical Biochemistry, 1965
Abstract A procedure is described for the quantitative determination of pyrrolidonecarboxylic acid by gas-liquid chromatography. The sample is treated with methanol containing hydrogen chloride; more than 97% of the pyrrolidonecarboxylic acid present is converted to the corresponding methyl ester under these conditions.

Pyrrolidonecarboxylic Acid at the N-Terminal Positions of Polypeptide Chains from Leopard Shark Immunoglobulins

The Journal of Immunology, 1970
Abstract Leopard shark immunoglobulins are found in 7S and 17S forms, which are indistinguishable chemically and antigenically, and probably are analogous to IgM molecules of mammals (1). The two molecular forms thus appear to share common H and L polypeptide chains.

The Influence of Variety on the Pyrrolidonecarboxylic Acid of Canned Beets

Journal of Food Science, 1964
SUMMARY The greatest amount of pyrrolidonecarboxylic acid (PCA) found in any of 10 varieties of processed beets was less than has been reported to be necessary to cause a flavor defect. The difference in PCA content between the varieties of canned diced beets containing the greatest and smallest amounts of PCA was less than reported ...

[18] Terminal pyrrolidonecarboxylic acid: Cleavage with enzymes

1972
Publisher Summary An enzyme preparation is used in structural studies on pyrrolidoneearboxylie acid (PCA)-peptides and PCA-proteins. The difficulties and frustrations of determining the structures of peptides with blocked amino-terminal groups led to search for an enzyme that could open terminal pyrrolidone rings.
