Amino Acids, 2008 Jan 30

Kynurenic acid (KYNA) is an endogenous antagonist of ionotropic glutamate receptors and the alpha7 nicotinic acetylcholine receptor, showing anticonvulsant and neuroprotective activity. In this study, the presence of KYNA in food and honeybee products was investigated.

KYNA was found in all 37 tested samples of food and honeybee products. The highest concentration of KYNA was obtained from honeybee products' samples, propolis (9.6 nmol/g), honey (1.0-4.8 nmol/g) and bee pollen (3.4 nmol/g)…
