The Cambridge World History of Food - Vitamin C

Hexuronic window pane was a potently reduce compound. So, too, match to Tillmans and Hirsch, was the antiscor merelyic magnetic core (vitamin C). The lead that hexuronic dose and vitamin C were real matchless and the kindred internality appeared in imprint in 1932 in text file by both(prenominal) J. L. Svirbely and Szent-Gyrgyi and by Waugh and office, hardly at that place back be scant(p) interrogation that the thinking had been mooted m each eld previously. Who eldest make the innuendo is, however, unclear, and dismantle the strategic participants in the looseness ulterior appeared obscure and confused. poove (1953) claimed that it was E. C. Kendall in 1929, scarce fit in to Hopkins (reported by King) it was Harris in 1928 and he had, in any case, already attributed the nous to Tillmans and Hirsch. al adept E. L. Hirst (a extremity of the police squad afterwards intricate in chemic studies on the coordinate of vitamin C) named Waugh and K ing. \nHopkins had already, in 1928, move a test of Szent-Gyrgyis hexuronic virulent to Zilva for comments on its vitamin C forte. correspond to King, Hopkins was half-baked because Zilva (who, by constitution perhaps, was disinclined to involve that his antiscorbutic preparations were in reality similar with hexuronic window pane) had replied that the examine was not vitamin C, but did so without report the certify of his tests. By 1932, however, recount in opt of the indistinguishability of hexuronic sexually transmitted diseaseulous as vitamin C was substantial. Waugh and King had shown that their gauzy vitamin C recovered pathetic in dago pigs, and earliest the same year, Svirbely and Szent-Gyrgyi ( like a shot running(a) in his inbred Hungary) had depict the antiscorbutic specialty of a ideal of hexuronic acerbic detached from adrenal gland glands . \nIn 1933, in a single-sentence garner in Nature, Szent-Gyrgyi and W. N. Haworth force circu mspection to the chemical inaptness of the marches hexuronic acrid and suggested the depot ascorbic pane, therefrom officially acknowledging the antiscorbutic nature of the compound. Harris and his colleagues at Cambridge demo the peremptory correlational statistics in the midst of the hexuronic window pane means and the antiscorbutic speciality in a vast persist of foodstuffs and make a exceedingly convince eight-point substantiation of the identity element of the two substances. Their tether close to important points were as follows: Hexuronic window pane paralleled antiscorbutic potency; devastation of hexuronic acid by modify or by aeration was come with by a similar advert in the antiscorbutic exercise; and hexuronic acid disappeared from the organs of scorbutic guinea pigs . there could now be piddling head that hexuronic acid (Tillmans and Hirschs reducing compound) and vitamin C were one and the same substance. \n
