sokeriyksikön

Sokeriyksikön is a Finnish term used in biochemistry to denote a monosaccharide residue, i.e., a single sugar unit, that constitutes part of a carbohydrate polymer or glycoside. The concept is used especially when describing oligosaccharides and polysaccharides, where individual sugar units serve as repeating or terminal residues. Common sugar units include hexoses such as glucose and galactose, as well as pentoses such as ribose and xylose, along with various modified forms.

In carbohydrate chemistry, sugar units are connected by glycosidic bonds to form disaccharides, oligosaccharides, and polysaccharides. Each unit retains specific stereochemistry and may participate in glycosidic linkages at particular carbon atoms (for example, α-1,4- or β-1,4- linkages in starch and cellulose, respectively). The identity and modification of a sokeriyksikön influence the properties of the carbohydrate, including digestibility, solubility, and reactivity.

In Finnish usage, sokeriyksikön is the genitive form of sokeriyksikkö, used to express possession or relation, for example sokeriyksikön koostumus (the composition of a sugar unit) or sokeriyksikön sidos (the bond within or to a sugar unit). The term appears in academic discussions of carbohydrate structure, glycosylation, and related biosynthetic pathways.
