{"product_id":"peritrophic-membranes-von-werner-peters","title":"Peritrophic Membranes","description":"Peritrophic membranes are secretion products of the midgut. For long they have been related only to insects, but they occur widely in the animal kingdom. They effect a part of the gut lumen and function not only as a mechanical protection barrier, but also as an ultrafilter, a barrier to parasites, and as envelopes for fecal pellets. Such peritrophic envelopes are of great ecological importance in marine environments. The book is divided into the following themes: - Occurrence - Formation and Structure - Degradation - Chemical Composition - Functions. It is the first comprehensive compilation of all data concerning peritrophic membranes and will provide a basis for future researches in this up to now often neglected field.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783642844164\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783642844164","offer_id":39432296235101,"sku":"9783642844164","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/adf65c12-b568-4666-bda8-aaa709ba7537.jpg?v=1778388406","url":"https:\/\/shop.autorenwelt.de\/en\/products\/peritrophic-membranes-von-werner-peters","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
