any one of a class of fibrous proteins found in the membranes of red blood cells, the brain, the intestine, etc
Word origin
C20: from spectr(e) + -in, referring to the ghosts (isolated cell membranes) of red blood cells, the sourceof the first known member of the class
spectrin in American English
(ˈspektrɪn)
noun
Biochemistry
a rodlike structural protein of the red blood cell membrane
Word origin
[1968; spect(e)r (cf. ghost def. 12) + -in2]-in is a noun suffix used in a special manner in chemical and mineralogical nomenclature(glycerin; acetin, etc.). In spelling, usage wavers between -in and -ine. In chemistry a certain distinction of use is attempted, basic substances havingthe termination -ine rather than -in (aconitine; aniline, etc.), and -in being restricted to certain neutral compounds, glycerides, glucosides, and proteids(albumin; palmitin, etc.), but this distinction is not always observed
