ferratin Biochem.|ˈfɛrətɪn|
[f. L. ferrāt-us containing iron + -in1.]
A substance formerly supposed to be an iron-containing protein that occurs esp. in the liver (see quot. 1946).
1893O. Schmiedeberg in Practitioner Dec. 427, I have now..succeeded..in isolating it in an unmixed condition from pig's liver. It contains, on the average, 6 per cent. of iron, and may briefly be referred to as Ferratin. Ibid., Ferratin is the only combination of iron which is ingested with food, and which is found stored up in the tissues as a reserve-material for the formation of blood. 1909Chem. Abstr. III. 2008 Schmiedeberg prepared ‘ferratin’ and called it a ‘ferrialbuminic acid’ of 6% Fe content... The compd. is not a ‘ferri⁓albuminic acid’ but is an Fe-containing nucleo-protein. 1930Proc. Soc. Exper. Biol. & Med. XXVIII. 294 The serum of a rabbit treated with sheep ferratin gave precipitin reactions with beef, hog and sheep ferratins..but not with any of the corresponding sera. 1946Chem. Rev. XXXVIII. 381 According to Schmiedeberg..the iron was attached to a protein and this compound, which he called Ferratin, was present in spleen, liver, and marrow... (Today we know that this compound was a mixture of denatured ferritin and denatured proteins.) |
