                                Beta-glucans, a type of polysaccharide found in sources like oats and yeast, have been researched for decades for their potent health-promoting properties. These complex carbohydrates, collectively known as glucans, play crucial roles in biology, ranging from structural support in organisms to modulating the human immune system. Understanding the purpose of glucan provides insight into how these molecules can be harnessed for nutritional and therapeutic benefits.
