Glossary Term: Glucan


1. Glucans are a class of glucose polymers and include starch ((α1-4)-glucan) and cellulose ((β(1–4)-glucan)). β-glucans occur widely and are structural cell wall components of yeasts, fungi, algae, lichens, and bacteria.
2. Although Chitin provides the crucial mechanical strength of the fungal cell wall, glucans make up 50–60% of the dry weight of the filamentous fungal cell wall. Approximately 65% – 90% of the cell wall glucan is β-1,3-glucan. Glucans are the major filamentous components of the cell wall structure that account for more than half of the dry weight of a budding yeast cell wall, and are required for correct functioning of the cell wall.
