myrosinn.

Brit.

/ˈmɪrəsɪn/,

/ˈmʌɪrəsɪn/, U.S.

/ˈmaɪrəs(ə)n/

Forms: 1800s myrosyne, 1800s– myrosin, 1800s– myrosine.

Origin: A borrowing from French. Etymon: French myrosine.

Etymology: < French myrosine (A. Bussy 1840, in Jrnl. de pharmacie 26 44; compare German Myrosyne (A. Bussy 1840, in Ann. der Chem. u. Pharm. 34 224)) < ancient Greek μύρον unguent, perfume (see myronic adj.) + French -ine -in suffix¹, with epenthetic -s- (perhaps, as suggested by Trésor de la langue française, after émulsine emulsin n.).With myrosin cell compare French cellule à myrosine (1890) and German Myrosinzelle (1905; compare also German Myrosinbehälter (1909 in the passage translated in quot. 1914 for myrosin cell n. at Compounds)). N.E.D. (1908) gives only the pronunciation (məi^ə·rŏsin) /ˈmaɪərəsɪn/.

Biochemistry. = myrosinase n.

1840 J. Pereira Elements Materia Medica 1267 Black mustard contains myronate of potash, myrosyne, fixed oil [etc.].

1873 F. H. Hooker & J. D. Hooker tr. E. Le Maout & J. Decaisne Gen. Syst. Bot. 232 Black mustard..contains a fixed..oil... This volatile oil..is produced by the action of a peculiar albumine (myrosine) on the myronic acid contained in the seed.

1874 Nature 3 Sept. 372/1 Myrosin..similarly induces the formation of oil of mustard.

1901 Science 17 May 767/2 Myrosin, the mustard ferment, is found not only in the many species and varieties of Cruciferæ, but in many other natural orders of plants as well.

1968 I. L. Finar Org. Chem. (ed. 4) II. 302 Allyl isothiocyanate is produced by rearrangement when the glycoside is hydrolysed by myrosin.

1993 New Phytologist 123 100/1 The glucosinolates and myrosinase appear to be compartmented in different regions of myrosin idioblasts.

Compounds

myrosin cell n. Botany a specialized plant cell in which myrosinase is stored.

ΚΠ

1914 M. Drummond tr. G. Haberlandt Physiol. Plant Anat. x. 529 The distribution of myrosine-cells in the vegetative organs of the aforesaid plants is subject to considerable variation.

1975 Ann. Missouri Bot. Garden 62 771 In erecting the order Capparales, Cronquist noted that ‘nearly all of the Cruciferae and many of the Capparaceae have specialized myrosin cells, which are chiefly though not entirely restricted to this order’.

1996 Ecology 77 2313/1 The myrosinase is compartmentalized separately in myrosin cells, and is released upon tissue damage.
