title: On the existence of 'bis (L-glutamine) potassium nitrate' crystal.
abstract: The slow evaporation of an aqueous solution containing L-glutamine and potassium nitrate in 2:1 mol ratio results in the fractional crystallization of L-glutamine and not the formation of a so called bis (L-glutamine) potassium nitrate as reported recently by Hanumantharao and Kalainathan (2012).
