Oat beta glucan is a natural soluble fiber. It is a viscous polysaccharide made up of units of the monosaccharide D-glucose.Oat is a rich source of the water-soluble fiber (1,3/1,4) β-glucan. Oat beta glucan is composed of mixed-linkage polysaccharides. This means the bonds between the D-glucose units are either beta-(1→3) linkages or beta-(1→4) linkages. The (1→3)-linkages break up the uniform structure of the beta-D-glucan molecule and make it soluble and flexible.
In comparison, the indigestible polysaccharide cellulose is also a beta glucan, but is not soluble. The reason it is insoluble is cellulose consists only of (1→4)-beta-D-linkages. Oat beta glucans are large molecules. Originally in the oat kernel, it is composed of up to 200,000 glucose units, which gives molecular weights in the range of 1500-3000 kDa.
Structure Formula :-
Oats are generally considered more healthy and nutritious than the other main cereals, well-known for the benefits of digestion and eaten during hundreds of years by both animals and humans.
Cholesterol-lowering properties -
Especially for the metabolic syndrome. In the last years, clinical studies have proved health benefits like avoiding heart diseases by maintaining/lowering cholesterol, decreased blood sugar response after eating – and also improving the gut health.
Cardiovascular disease (CVD) -
High cholesterol is a risk factor in the development of coronary heart disease. The latest research demonstrates that oats and oat beta glucan can be recommended as part of a healthy diet to reduce the risk of CVD.
Oats are a naturally rich source of beta-glucan. The effect of oat beta-glucan on both serum cholesterol and blood glucose reduction is proven. Internationally recognized associations, such as the European Society of Cardiology and the US National Cholesterol Education Program, and the recent meta-analysis, support the role of oat beta-glucan, and specifically its viscosity in lowering blood cholesterol levels.
In 1997, the FDA approved of a claim that intake of at least 3.0 g of β-glucan from oats per day decreased absorption of dietary cholesterol and reduced the risk of coronary heart disease.
