On the existence of 'l-threonine formate', 'l-alanine lithium chloride' and 'bis L-alanine lithium chloride' crystals

摘要

We argue that the recently reported crystals "l-threonine formate" as well as "l-alanine lithium chloride" and "bis l-alanine lithium chloride" actually are the well-known crystals l-threonine and l-alanine, respectively.
