a type of blue pigment or protein which is found in some algae
phycocyanin in American English
(ˌfaikouˈsaiənɪn)
noun
Biochemistry
a blue protein pigment, found in algae, involved in the process of photosynthesis
Word origin
[1870–75; phyco- + cyan-1 + -in2]This word is first recorded in the period 1870–75. Other words that entered Englishat around the same time include: asymmetric, fifth wheel, immobilize, onshore, washout-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
