The edible and medicinal perennial herb dandelion is known to have antitumor, antioxidant, and anticomplement properties. However, the structural characterization and biological effects of its polysaccharides are not well understood. Here, we aimed to extract and investigate a novel polysaccharide from dandelion. A water-soluble polysaccharide, PD, was successfully obtained from dandelion through ultrasonic-assisted extraction and purification using diethylaminoethyl DEAE —Sepharose fast flow and Sephadex G columns. The results showed that PD is an inulin-type polysaccharide with a molecular weight of 2.
Physical properties of monosaccharides. Monosaccharides are colourless and crystalline compounds. They are readily soluble in water. They have sweet tase. D-glucose and L-glucose are mirror images of each other.
McGrane, Mary M. Center for Nutrition Policy and Promotion, U. Department of Agriculture, Alexandria, Virginia. Last reviewed: April Any of the group of organic compounds consisting of carbon, hydrogen, and oxygen that includes sugars, starches, and cellulose. Carbohydrate compounds consist of carbon, hydrogen, and oxygen, with the general chemical formula C m H 2 O n [ Fig. As their name suggests, carbohydrates are hydrates water-containing solid compounds of carbon.

Moreover, it was a contributing factor in over , deaths in which the cause was listed as something else, such as heart or kidney disease. People with diabetes are impaired in their ability to metabolize glucose, a sugar needed by the body for energy; as a result, excessive quantities of glucose accumulate in the blood and the urine.
Monosaccharides such as glucose and fructose are crystalline solids at room temperature, but they are quite soluble in water, each molecule having several OH groups that readily engage in hydrogen bonding. The chemical behavior of these monosaccharides is likewise determined by their functional groups. An important reaction of monosaccharides is the oxidation of the aldehyde group, one of the most easily oxidized organic functional groups. These reactions have been used as simple and rapid diagnostic tests for the presence of glucose in blood or urine. Monosaccharides are crystalline solids at room temperature and quite soluble in water.
Monosaccharides have many physical and chemical properties; we will discuss some of these properties. I- Asymmetric carbon atom. It is that carbon which is.
Saccharides are better known as carbohydrates literally hydrates of carbon. Relatively complex carboyhydrates are known as polysaccharides. The simplest carbohydrates are monosaccharides, which are small straight-chain aldehydes and ketones with many hydroxyl groups added, usually one on each carbon except the functional group. Monosaccharides are the building blocks of disaccharides such as sucrose and lactose and polysaccharides such as cellulose and starch.

Monosaccharides sugars are organic chemical compounds and the most basic unit of carbohydrates. A disaccharide is a sugar composed of two monosaccharides. With Sugar, we first of all connect the sweet-tasting table sugar - a double sugar called sucrose. Chemically the monosaccharides simple sugars form the basic building blocks of the carbohydrates.

Monosaccharides from Greek monos : single, sacchar : sugar , also called simple sugars , are the simplest form of sugar and the most basic units monomers of carbohydrates.Urban T. 27.03.2021 at 05:48
