glikosidik

Glikosidik is a term used in biochemistry and related languages to refer to concepts connected with glycosides and glycosidic linkages. In contexts describing chemical bonds between a sugar moiety and another molecule, glikosidik-related terminology covers glycosidic bonds, which can involve oxygen, nitrogen, or sulfur atoms and are often described as O-, N-, or S-glycosidic bonds. The term may appear in translations or linguistic variants of the English word glycosidic or glycoside, depending on the language.

Glycosidic bonds are formed by a condensation reaction between the anomeric carbon of a sugar and a functional group on the aglycone (the non-sugar portion). The resulting glycoside can be hydrolyzed by acids or by specific enzymes, releasing the sugar and the aglycone. The bond can be classified by the atom linking the sugar to the acceptor (O-, N-, S-glycosidic) and by the stereochemistry at the anomeric center (alpha or beta), both of which influence stability and enzymatic susceptibility.

In nature and industry, glycosides are widespread. Plants often produce glycosides as storage forms, defense compounds, or biologically active molecules. Examples include salicin, amygdalin, and various cardiac glycosides such as digitoxin. The study of glycosidic bonds and glycosides informs fields ranging from plant biology and nutrition to pharmacology and drug development.
