IPA: /ˈɡluː.kən/
KK: /ˈɡluːkən/
A type of carbohydrate made up of many glucose molecules linked together, often found in plants and fungi.
Glucan is an important component of the cell walls in certain fungi.
Glucan is derived from "glucose" (from Greek "glukus", meaning sweet) and the suffix "-an" (used to form nouns indicating a substance). The word "glucan" refers to a type of polysaccharide that is composed of glucose units.
Think of 'glucose' which means sweet, and remember that 'glucan' is a substance made from glucose.
