Растительные полисахариды

Среди полисахаридов наиболее важными являются два полимера глюкозы растительного происхождения: целлюлоза, в которой остатки глюкозы связаны в положении β(1→4), и крахмал, в котором основной тип связи α(1→4).

 
А. Целлюлоза

Целлюлоза, линейный гомогликан построенный из остатков глюкозы, связанных в положении β(1→4), является самым распространённым органическим соединением. В клеточных стенках растений целлюлоза составляет 40-50%, ...

А. Целлюлоза
Б. Крахмал

Крахмал, широко распространённый резервный полисахарид растений, является наиболее важным углеводным компонентом пищевого рациона. В растениях крахмал содержится в хлоропластах листьев, плодах, семенах и клубнях. ...
