laminaran

Laminaran is a β-1,3-glucan isolated from brown algae, often serving as a typical ligand for Dectin-1. It possesses anti-cancer, immune-modulating, and radiation-protective properties. Laminaran can be catalyzed by glucanase. In in vitro and in vivo experiments, Laminaran has demonstrated anti-tumor activity and may be used for severe cancers.

β-1,3-Glucan is a major constituent of all characterized fungal cell walls, comprising 30% to 80% of wall mass, and β-1,3-Glucan exists as a branched polymer in the cell wall, with branches connected via β-1,6 linkages, enabling investigation into fungal structural biology, cell wall assembly, immunomodulation, and antifungal therapeutic targeting.
