Pyruvic acid INDEX

Table V is also an index to Table I it classifies the compounds according to the functional groups they contain. One frequently wants to examine data on carbonyl compounds, on unsaturated or halogenated ketones, or another more or less specific class of substances, and the purpose of Table V is to simplify searches of this sort. Pyruvic acid appears in Table V both among the ketones and among the carboxylic acids, and Inspection of either group would quickly reveal any closely related compound that appears in this volume.

In thiamine deficiency, pyruvate accumulates in the blood and tissues and there is a change in the lactate-pyruvate ratio. These findings have been used in detecting thiamine deficiency in man. MIorwitt has proposed as a test of thiamine nutrition the simultaneous measurement of lactic acid, pyruvic acid, and glucose in the blood 5 min. after mild exercise and 60 min. after ingestion of glucose. The carbohydate index (C.I.) is determined from the formula...
