LC‐MS‐Based Metabolic Fingerprinting of Aqueous Humor
Journal of Analytical Methods in Chemistry, Volume 2017, Issue 1, 2017., 2017 Aqueous humor (AH) is a transparent fluid which fills the anterior and posterior chambers of the eye. It supplies nutrients and removes metabolic waste from avascular tissues in the eye. Proper homeostasis of AH is required to maintain adequate intraocular pressure as well as optical and refractive properties of the eye.

In vivo kinetics of pyrrolidonecarboxylic acid formation in selected silkmoth chorion proteins.
Journal of Biological Chemistry, 1981 The protein products from one of the two major silkmoth chorion multigene families contain blocked NH2 termini. The blocked residue has been identified as pyrrolidonecarboxylic acid. Its formation occurs post-translationally, by modification of NH2-terminal glutamine, after removal of a 20-residue-long "signal peptide." Pyrrolidonecarboxylic acid ...

Gas Chromatographic Determination of Pyrrolidonecarboxylic Acid
Journal of AOAC INTERNATIONAL, 1970 Abstract An analytical method is described for analysis of 2-pyrroIidone-5-carboxylic acid (PCA) in foods. PCA was extracted with ethyl acetate, using a modified Widmark extraction apparatus, and then silylated with trimethylchlorosilane and hexamethyldisilazane in the presence of pyridine.

The Synthesis of γ-Alkylamides of
Bulletin of the Chemical Society of Japan, 1966 Abstract l-Theanine, a principal component of flavors contained in green teas, and its homologs have been synthesized by the reactions of several metallic salts of l-pyrrolidonecarboxylic acid with primary alkylamines. Hitherto, γ-alkylamides of l-glutamic acid had been prepared in low yields by the reactions of l-pyrrolidonecarboxylic ...

Ring Opening of Pyrrolidonecarboxylic Acid via a Metal Chelate
Agricultural and Biological Chemistry, 1989 l-Pyrrolidonecarboxylic acid (PCA) is a cyclic compound derived on intramolecular dehydration of l-glutamic acid. The conventional method used for the conversion of PCA to glutamic acid has been hydrolysis with strong acids or alkalis at high temperatures.
