Polysaccharides have a general formula of Cx(H2O)ywherexis usually a large number between 200 and 2500. Considering that the repeating units in the polymer backbone are often six-carbon monosaccharides, the general formula can also be represented as (C6H10O5)nwhere where 40<n<3000.. WHAT IS ...

Formula Mass Formula mass is defined as the sum of the atomic weights of the atoms in the given molecule of the substance. For example, the formula mass of Na₂S is calculated as 2(23) + 1(32) = 78.Avogadro number Avogadro’s number is the total number of particles in one mole ...
These are the many properties which can be used to describe a chemical, such as its formula, its melting point, pKa , lopP, molecular orbital data, electrophilicity and so on. Data on these properties is used to build quantitative structure-activity relationships. Chemical Structure and the Gene...
Among these components, flavonoids and polysaccharides were the representative active ingredients of T. hemsleyanum, which have been widely investigated. Modern pharmacological studies have shown that these components exhibited various pharmacological activities, such as anti-inflammatory, antioxidant, antivirus...
