3. Introduction β-glucans are polysaccharides of D-glucose monomers linked by β-glycosidic bonds. Composed of about 20-30 glucose units with side chains.They are derived from the cell wall of - baker’s yeast, fungi, bacteria, mushrooms, oats, bran, wheat, and barley.Nowdays, the popularity of β-glucans as food additive and a disease-modifying agent is increasing.β-glucans is one form of soluble dietary fiber that’s strongly linked to improving cholesterol levels and boosting heart health.
4. Occurrence of beta-glucansPredominantly found in the aleurone and sub-aleurone cell walls .β-glucans content varies with endosperm development and is regulated by (1-3, 1-4) β-glucan endohydrolase .β-glucans are naturally occuring polysaccharides found in the cell walls of plants, cereals, grains, algae, yeast, bacteria, and fungi.Cell wall of baker’s yeast, that Saccharomyces cerevisiae is most abundant in β- glucans.

7. Properties of β-glucansPhysiological effects of beta- glucans are mainly to its physiochemical and structural properties.Properties of beta – glucans to generate viscous solutions at low concentration and ability to undergo fermentation are the potential first-line intervention in the treatment of metabolic syndrome. These are influenced by the following properties Viscosity and geiling properties . Foaming capacity and foam stability. Water binding properties.
8. Mechanism of beta- glucans
9. function of beta- glucans Immune system support: β-glucans may be especially, beneficial for people whose immune system have been compromised due to chronic fatigue and emotional stress. It may also help pepole whose breathing patterns need support it affected by seasonal conditions.Digestive support :Beta –glucans may help the systems of poor digestive, including bloating, gas and discomfort. Heart health support :Carsdiovacular health may also be supported by beta-glucans, especially the management of a healthy cholestrol profile. Healthy circulation support: Beta-glucan may also help people maintain a healthy circulation, especially those with a high body mass index.
10. Health benefits of beta glucansβ- glucans is the most powerful immune stimulant know. β- glucans prevent infection of viral diseases. Stimulates the macrophage of the immune system.Prevents the insuline resistance prevention of coronary heart disease. Production of short chain fatty acid.Stimulates both humoral and cellular immunity. Since , β-glucans tend not to be degraded by human enzymes, they have a natural nutritional fiber property.Promotes the growth of beneficial gut microflora, (prebiotic). Prevents the hepatic damage. Wound healing and rejuvenates the skin. Prevents the coronary heart disease.
11. Side effects of β-glucans Beta –glucans can be taken orally or an injection. Doctor recommend taking beta glucan as a suppliments since there are little or no side effects. The few common side effects include: diarrhea nausea vomiting. If your doctor needs to inject beta glucans directly into your bloodstrem, you may experience other adverse side effects including: back pain joint pain chills fever irregular blood sugar diarrhea
