L-raminosi monoidrato CAS 6155-35-7

Product name: L-Rhamnose Monohydrate Molecular Formula: C6H14O6 Molecular Weight: 182.172 CAS No.: 6155-35-7 Description Rhamnose is a white crystalline granule or powder. It is soluble in water and methanol, slightly soluble in ethanol. Its crystal forms in two forms, α type and β type. The α type contains one molecule of water of crystallization, loses crystal water after heating, and is converted into β type (molecular weight: 164.16); the β type is extremely hygroscopic and converts moisture into α in the air. Commonly used is α-L-rhamnose, which has a molecular weight of 182.11. Application L-Rhamnose Monohydrate is a methyl pentose sugar and has properly been classified as one of the rarer sugars. This sugar is a constituent of many glycosides. The rhamnoglycoside of quercetin (rutin) has been most often used as a source of rhamnose and after its hydrolisis, it yields the aglycon and L-Rhamnose. Rhamnose finds use in the flavor industry as a starting material for the production of furanones, as well as the starting raw material in reaction flavors developed during the preparation of various foods such as bread, grilled meats, etc. Its sweetness is 33% of sucrose, which can be used to determine the intestinal permeability, and can be used as a sweetener.
