Beta-(1,3)-D-glucan is a type of polysaccharide found in the cell walls of certain fungi, bacteria, and plants. It consists of glucose molecules linked together in a specific arrangement, which contributes to its structural properties. This compound is known for its potential health benefits, particularly in supporting the immune system. Research has shown that beta-(1,3)-D-glucan can enhance the activity of immune cells, such as macrophages and natural killer cells. It is often used as a dietary supplement and is being studied for its role in improving overall health and combating infections.
