吡喃糖(英语:Pyranose)是一种糖,用于总称碳水化合物所具有的化学结构,其中包含一个由5个碳原子和1个氧原子所组成的六元环状结构。可能会有其他的碳原子在环以外。吡喃糖是吡喃的衍生物,但是吡喃糖环没有双键。如果吡喃糖1号碳上的异头羟基已经变为OR基团则被称为吡喃糖苷。

Pyranose is a collective term for carbohydrates that have a chemical structure that includes a six-membered ring consisting of five carbon atoms and one oxygen atom. There may be other carbons external to the ring. The name derives from its similarity to the oxygen heterocycle pyran, but the pyranose ring does not have double bonds. A pyranose in which the anomeric OH at C(l) has been converted into an OR group is called a pyranoside.
