释义	fibroin /ˈfʌɪbrəʊɪn / noun [mass noun] A protein which is the chief constituent of silk.Molecular elasticity is associated with a select number of polypeptides and proteins, such as titin, Lustrin A, silk fibroin, and spider silk dragline protein.... As water volume decreased and the concentration of fibroin increased, the proteins folded in on themselves, forming round structures called micelles. The mechanisms are not well defined, but iron and tin will promote the photo-oxidation of the silk fibroin. Origin Mid 19th century: from fibro- + -in1.
