A simple quantitative method for estimating nanomole concentrations of 5-pyrrolidone-2carboxylic acid (PCA) in tissue homogenates from mouse has been developed using reversephase HPLC. PCA was detected as the 4-nitrophenacyl ester which has an absorption maximum at 263 nm, a relatively high stabilit
