From: The effects of β-glucan on human immune and cancer cells
β-glucan is one of the key components of the fungal cell wall. The basic subunit of the fungal β-glucan is β-D-glucose linked to one another by 1→3 glycosidic chain with 1→6 glycosidic branches. The length and branches of the β-glucan from various fungi are widely different.
