Although they are often found in insects, peritrophic matrixes are found in seven different phyla. The peritrophic matrix serves several functions, including improvement of digestion, protection against mechanical and chemical damage and serving as a barrier to infection by pathogens. ==Chemical composition and structure== The peritrophic matrix is composed of regularly arranged chitin microfibrils, (3–13% of matrix mass), and species specific proteins (20–55%) embedded in a proteoglycan matrix. The peritrophic matrix also includes very small pores which allow for passage of small molecules into and out of the matrix. Thus, due to size limitations (pores reach a maximum size of 10 nm) larger, unwanted materials taken in while feeding are trapped and excreted along with the matrix.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Peritrophic matrix」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
