What is Oat Beta-Glucan?
Oat β-glucan is a non-starch polysaccharide present in oat endosperm and aleurone cell wall. Oats are mainly composed of chaff and endosperm, and the endosperm is wrapped by pericarp, seed coat, aleurone layer and subaleurone layer. Oat β-glucan is mainly located in the endosperm cell wall of the grain, and there is also a large amount of accumulation in the subaleurone layer.
The β-(1→3, 1→4) glucan in oats is referred to as oat β-glucan for short, which is a non-starch polysaccharide existing in oat endosperm and aleurone layer cell wall. It is a high molecular polymer formed by connecting monomer β-D-glucopyranose through β-(1→3) and β-(1→4) glycosidic bonds. Among them, the distribution of β-(1→3) and β-(1→4) glycosidic bonds is neither completely ordered nor fully ordered, mainly cellotriose or cellotetraose of β-(1→4) glucan , more than 85% of the oat β-glucan molecules have 1 β-(1→3) glycosidic bond between every 2~3 β-(1→4) glycosidic bonds, and 15% are composed of long chain β-glucans. The (1→4) glycosidic bond is separated by a β-(1→3) glycosidic bond, and its length may be 4, 5 or 8 glucose residues. A straight-chain unbranched polysaccharide structure with β-(1→3) bonds, where the ratio of β-(1→4) to β-(1→3) glycosidic bonds is about 2.4:1.
In oat endosperm and aleurone cell wall components, β-glucan accounts for more than 85%. Oat β-glucan is a short-chain glucan with a relatively small molecular weight, and its relative molecular weight ranges from 5300 to 257200.
The role of oat beta-glucan
● Lower Cholesterol
Scientists have found that the effect of β-glucan on cholesterol is that it can significantly reduce total cholesterol (TC) and low-density lipoprotein cholesterol (LDI-TC) in plasma, while it has high-density lipoprotein (HDL) and triglyceride (TG) No noticeable effect. Oat β-glucan has obvious cholesterol-lowering effect on people with high blood lipids, can reduce the rate of gastrointestinal absorption of fatty acids, and reduce the synthesis of cholesterol in the human body.
● Lower Blood Sugar
After eating dextran oat food every day, the patient's blood sugar level can be reduced by about 50%, and the use of oat food can significantly reduce blood sugar. Oat β-glucan can reduce blood lipid content, improve blood flow performance, accelerate the transfer speed and efficiency of sugar components in the process of absorption and utilization, and at the same time have a good repair effect on liver and kidney tissue lesions complicated by diabetes, and can effectively Decreases the breakdown of liver glycogen, which leads to lower blood sugar.
● Enhance Immunity
Oat β-glucan has immunoregulatory effects, oat β-glucan can make mouse lymphocytes proliferate, enhance the ability of mice to resist bacterial invasion; it can stimulate mouse peritoneal macrophages to release tumor necrosis factor (TNF-ALPHAhe) and The release of interleukin-1 (In-terlukinIL-1) and macrophage p338DI, after intragastric or parenteral injection of oat β-glucan, the number of serum immunoglobulins in mice increased significantly, indicating that oat β-glucan has the ability to improve small The role of mouse immunity.
● Anti-cancer Function
The short-chain fatty acids produced by the fermentation of oat β-glucan in the intestinal tract can reduce the activity of microbial metabolic enzymes such as glucosidase, glucuronidase and urease; the viscous β-glucan can also increase the secondary bile These enzymes and secondary bile acids are the inducing factors of colon cancer, so oat glucan has anti-cancer effects.
● Improve Gut
Oat β-glucan cannot be hydrolyzed in the small intestine, but degrades in the large intestine and serves as a substrate for bacterial fermentation, which produces short-chain fatty acids, especially butyric acid, which are beneficial to intestinal function. Oat β-glucan can be used as a prebiotic to promote human health. Oat β-glucan can form a gel-like network in the human body, change the viscosity of gastric and intestinal juice, increase the viscosity of chyme, and slow down the flow rate of chyme in the digestive tract. Oat β-glucan cannot be digested and decomposed by digestive enzymes, and can well inhibit the growth of mucosal food-loving bacteria in the intestine and stomach. Oat β-glucan can also increase the number of microorganisms and improve the intestinal tract by improving the breeding conditions of beneficial bacteria (such as lactic acid bacteria and bifidobacteria); in the large intestine, oat β-glucan is fermented by microorganisms, especially Fermented by lactic acid bacteria and bifidobacteria in the cecum to produce bifidobacteria that are beneficial to human health.
● Beauty Effect
Oat β-glucan has excellent anti-aging effects, can smooth fine wrinkles, improve skin elasticity, and improve skin texture; it has a unique straight-chain molecular structure, which endows good transdermal absorption properties; promotes fibroblasts Synthesize collagen, promote wound healing, repair damaged skin, and give skin a silky moist and smooth touch.
● Increase Satiety
Oat β-glucan improves postprandial satiety, possibly due to the non-digestible properties of β-glucan in the gastrointestinal tract. In addition, studies have shown that oat beta-glucan plays an important role in reducing belly fat and obesity, mainly in reducing body weight, body mass index, body fat and waist-to-hip ratio.
