Oats are rich in protein, unsaturated fatty acids, dietary fiber, and a variety of micronutrients, and the proportion of oats used in food has increased greatly in recent years.

Many studies at home and abroad have proved that oats have important nutritional and health care effects, and regular consumption can effectively reduce serum cholesterol, triglyceride and serum LDL cholesterol levels; Oats are also an ideal food for diabetics; Oats also have a variety of functions such as improving intestinal function and fighting bowel cancer. These health effects of oats are mainly due to the fact that they are rich in bioactive polysaccharides B-glucan.

Oat P-glucan is mainly found in the cell wall of the aleurone layer and the sub-aleurone layer, and is a linear macromolecular viscous non-starch polysaccharide composed of uniform D glucose pyranosyl units linked by P-(1-3) and B(1-+4) glycosidic bonds. In recent years, a large number of studies have been carried out on the extraction, structure, physicochemical properties and physiological functions of oat B-glucan at home and abroad, which play a major role in understanding the nutritional function of oat B-glucan and the research and development of oat B-glucan functional food.

b Many physiological functions of dextran in the human body are related to its viscosity, and its viscosity depends on it.

relative molecular weight, molecular structure and concentration of B-glucan. The study by Michelal et al. (1997) showed that the molecular weight of B-glucan varies with the variety, origin, extraction method and determination method, and generally varies from .

4 4x 104 to 3 0x t06. And the relative molecular weight of oat13 dextran is greater than that of barley. When with water.

When extracted, the extraction temperature had little effect on its relative molecular mass, but the 13··13·

The relative molecular weight of dextran was significantly lower than that of dextran extracted in water. Katarina et al. noted that the concentration was consistent.

Under these conditions, the viscosity of B-glucan in oat bran is greater than that of B-glucan in endosperm, so it is okay.

It is estimated that the relative molecular weight of 13-glucan in oat bran is higher than that of b-glucan in endosperm.

Yeast dextran is also known as dextran. is a polysaccharide.

Present in the mucus secreted by some microorganisms during growth, modern studies have found that Agaricus mushroom contains the most abundant B-glucan and has high biological activity. Dextran has a high molecular weight, mainly by d grape pyranose linked by , 1 6 bonds, branched points have 4 links, and -1,3 -1,6 bound -glucan has the highest biological activity. Depending on the type of microorganism and the conditions under which it grows, so does its structure and function.

Glycans refer to homopolysaccharides composed of glucose as a monosaccharide, and glucose units are connected by glycosidic bonds. According to the type of glycosidic bond, it can be divided into alpha-glucan and beta-glucan. Among the alpha-glucan that is most studied and used, dextran, also known as dextran.

is a polysaccharide. It is present in mucus secreted by certain microorganisms during growth. Dextran has a high molecular weight, mainly connected by d grape pyranose with , 1 6 bonds, and 4 links at the branching points.

Depending on the type of microorganism and the conditions under which it grows, so does its structure.

Basic characteristics: 1. It is one of the bacterial polysaccharides, also known as dextran, which is produced by the bacteria cultivated in sucrose solution [Leuconostoc enterospermica, dextran sucrase, dextran venuctoctobacterium catalyzed by the following reactions: N sucrose dextran + N fructose. In the industrial subsp. oxidized Glucobacterium [previously the bacteria containing this substance were called Acetobacterium viscosus and Acetobacterium capsulatus, dextran is synthesized from dextrin.

There are many types of dextran, which are composed only of D-glucose, and the backbone is (1,6) bonds, and there are branched chains with (1,4) or (1,3) bonds. Glucose is a white powder, and adding a little bit to water produces strong dextinator. It is used as a substitute plasma in medicine.

2. It is a general term for polysaccharides with glucose as the constituent sugar. Due to the different binding styles of D-glucose residues, they are divided into many kinds and are widely distributed in microorganisms, plants and animals. Among the representative ones are polyglycosis of bacteria, kelp polysaccharides of brown algae, xylan of lichens (-1,4 and -1,3 bonds), cellulose of higher plants (1,4 bond), amylose (-1,4 bonds), amylopectin (side chains of -1,6 bonds on the main chain of -1,4 bonds), glycogen of animals, etc.

Dextran is the polysaccharide with the highest content of Candida albicans cell wall. According to the solubility of -dextran, it can be divided into insoluble and soluble-dextran, where soluble-dextran includes alkali-soluble and acid-soluble dextran. According to the differences in sugar chain structure, -(1, 3)-dextran and -(l6)-dextran can be divided.

Methylation and CNMR analysis studies have demonstrated that acid-soluble dextran** is a highly branched 1-4-chain linked polymer to yeast, mycelium and mycelium-forming cells. Insoluble dextran in yeast cell and hyphal cell walls consists of a mixture of 30% 40% -(1 3)-glucan and 43% 53% -(1 6)-glucan.

Dear, I am glad to serve you to answer Oh, the role and efficacy of dextran are: dextran has the effect of improving the body's immunity and regulating the digestive tract flora. Dextran is able to resist viral and bacterial infections, and is suitable for patients who have been in a sub-healthy state for a long time, which can improve immunity.

Dextran can quietly balance and effectively regulate the flora of the digestive tract, promote the increase of beneficial bacteria in the body and the excretion of harmful substances in the intestines.
