Pyranoside

Part of speech: noun

Definitions

1. A compound in which a sugar molecule forms a ring with six members including five carbons and one oxygen, linked to another molecule through a glycosidic bond ; a sugar derivative where the cyclic structure is a six-membered ring, typically associated with carbohydrate chemistry ; a chemical entity involving a hexagonal ring of sugar atoms connected by an ether-like linkage to another group or molecule
2. A molecule featuring a sugar ring composed of five carbon atoms and one oxygen atom bonded to a non-sugar moiety through an oxygen bridge ; a carbohydrate-related compound with a six-membered ring structure forming a glycosidic connection to another compound ; a biochemical substance utilizing a hexose ring as the core sugar unit attached via an oxygen atom to a separate molecular entity
3. A type of sugar derivative characterized by a six-membered ring containing five carbons and one oxygen, connected to another molecule through a covalent glycosidic bond ; a sugar-based compound with a pyran ring structure serving as the glycone moiety in glycosidic linkages ; a carbohydrate compound where the sugar component is in a hexagonal ring form bonded to another chemical fragment through an oxygen atom

Etymology: "Pyranoside" is a chemist's construction. The "pyran" part names the six-membered ring of five carbons and one oxygen. Its name likely traces back to "pyrrole," a related ring compound named from the Greek "pyrrhos," meaning flame-coloured, because pine wood moistened with acid turns red. "Pyran" was probably formed by analogy with that name, using the common "-an" ending for ring compounds. The ending "-oside" comes from "glycoside," a term for a sugar bonded to another molecule. "Glycoside" is built from the Greek "glykys," meaning sweet, which also gives us "glucose," and the suffix "-ide" marks a compound of this kind. Joined together, the name specifies a sugar whose ring is a pyran.

Synonyms: pyranose glycoside
