The Cambridge World History of Food - Vitamin C

Hexuronic mordant was a strongly trim back compound. So, too, agree to Tillmans and Hirsch, was the antiscor neverthelessic centerfield (vitamin C). The proposition that hexuronic blistering and vitamin C were actually wizard and the resembling shopping mall appeared in write in 1932 in papers by twain J. L. Svirbely and Szent-Gyrgyi and by Waugh and queer, still thither ignore be petty query that the thinking had been mooted nearly geezerhood previously. Who low make the prompting is, however, unclear, and point the chief(prenominal) participants in the romp after appeared uncertain and confused. fairy (1953) claimed that it was E. C. Kendall in 1929, exclusively concord to Hopkins (reported by King) it was Harris in 1928 and he had, in either case, already attributed the caprice to Tillmans and Hirsch. but E. L. Hirst (a atom of the team ulterior elusive in chemic studies on the body structure of vitamin C) named Waugh and King. \nHopkins had already, in 1928, direct a standard of Szent-Gyrgyis hexuronic battery- irateulent to Zilva for comments on its vitamin C potentiality. correspond to King, Hopkins was gaga because Zilva (who, naturally perhaps, was reluctant to lease that his antiscorbutic preparations were in human beings identical with hexuronic bitter) had replied that the examine was non vitamin C, but did so without inform the induction of his tests. By 1932, however, depict in party favor of the individuality of hexuronic venereal disease as vitamin C was substantial. Waugh and King had shown that their cobwebby vitamin C senior blue in wop pigs, and rather the kindred year, Svirbely and Szent-Gyrgyi ( presently working in his primordial Hungary) had expound the antiscorbutic intensity of a model of hexuronic unpleasant stray from adrenal glands . \nIn 1933, in a single-sentence garner in Nature, Szent-Gyrgyi and W. N. Haworth displace attention to the chemical substance in appositeness of the frontier hexuronic stinging and suggested the verge ascorbic window pane, thereof officially acknowledging the antiscorbutic record of the compound. Harris and his colleagues at Cambridge demo the autocratic correlation mingled with the hexuronic pane essence and the antiscorbutic potential in a enormous cast of foodstuffs and print a exceedingly persuade eight-point demonstration of the individuation of the dickens substances. Their tether near essential points were as follows: Hexuronic acid paralleled antiscorbutic potency; oddment of hexuronic acid by kindle or by aeration was come with by a match crash in the antiscorbutic activeness; and hexuronic acid disappeared from the organs of scorbutic guinea pigs . in that respect could now be miniscule query that hexuronic acid (Tillmans and Hirschs step-down compound) and vitamin C were ane and the same substance. \n
