X.—On the basicity of tartaric acid

Significance of urinary tartaric acid.

Tartaric Acid Dehydrogenase Activity in Higher Plants1,2

Although the tartrates have been considered as possible metabolites in higher plants since the initial work of Pasteur in 1848, surprisingly little is known of their actual physiological significance. Vickery and Palmer (35) have briefly reviewed the history of (+)-tartrate in plants, including the problems of identification and of nomenclature. They conclude that (+)-tartrate is an uncommon pl...

l-Asparagine–l-tartaric acid (1/1)

In the title compound, C(4)H(8)N(2)O(3)·C(4)H(6)O(6), the amino acid mol-ecule exists as a zwitterion and the carb-oxy-lic acid in an un-ionized state. The tartaric acid mol-ecules are linked into layers parallel to the ab plane by O-H⋯O hydrogen bonds. The amino acid mol-ecules are also linked into layers parallel to the ab plane by N-H⋯O and C-H⋯O hydrogen bonds. The alternating tartaric acid...

The Fate of Tartaric Acid in the Human Body*

Until recently no accurate method existed for the quantitative determination of small amounts of tartaric acid in the urine. In 1931 Underhill, Peterman, and Krause (1) reported a calorimetric method based upon the reaction between metavanadates and tartaric acid in which a golden red color results. We are able to report upon its accuracy, for this identical method was developed independently b...
