solanose

Solanose is a naturally occurring carbohydrates that belongs to the family of oligosaccharides. Chemically, it is a tetrasaccharide composed of four D-glucose units linked via α-1,4-glycosidic bonds, giving it the systematic IUPAC name (4′S)-α‑D‑glucopyranosyl‑3‑α‑D‑glucopyranosyl‑2‑α‑D‑glucopyranosyl‑D‑glucopyranose. The resulting structure is a straight-chain polyglucose that is distinct from more common branched forms such as maltose or cellobiose.

Solanose can be isolated from various plants, notably in the Solanaceae family, from which its name is derived. In addition, it has been identified in certain fungal species and in some bacteria that thrive in extreme environments. Unlike many oligosaccharides that act as energy reserves, solanose is mainly stored as a storage carbohydrate in some seed tissues. It is also detected in small amounts in fruit juices and in processed foods where plant extracts are used as flavorings or texturizing agents.

Biologically, solanose is generally considered non-toxic. In animal studies it has shown mild prebiotic effects, promoting the growth of beneficial gut microorganisms when administered in controlled amounts. Its mode of action is not as strong as that of inulin or fructooligosaccharides, but it nevertheless can influence gut microflora diversity. Human consumption of solanose is safe at typical dietary levels; no adverse health effects have been reported, and it is not currently classified as a food additive or sweetener in major regulatory lists. The compound has also been of interest in carbohydrate chemistry research, particularly in the study of glycosidic bond formation and enzymatic carbohydrate synthesis.
