carbohydratelike

Carbohydratelike is a descriptive term used to refer to molecules or materials that resemble carbohydrates in structural or functional aspects, without being true carbohydrates themselves. It is employed in chemistry, biochemistry, and materials science to describe backbones or architectures that mimic sugar units.

Typical features include multiple hydroxyl groups, stereogenic centers, and, in some cases, cyclic forms reminiscent of pyranose or furanose rings. Such molecules can exhibit hydrogen-bonding patterns and conformations similar to carbohydrates, enabling interactions with carbohydrate-binding proteins.

The term covers both sugar derivatives and non-sugar scaffolds designed to imitate carbohydrate topology. Carbohydratelike compounds may be polyhydroxylated polymers, sugar mimetics, or glycomimetics that resist or modify enzymatic processing, sometimes serving as enzyme inhibitors or ligands for lectins.

In medicinal chemistry, carbohydratelike structures are used to probe glycan recognition and to develop inhibitors of glycosidases or viral lectin binding. In materials science, they contribute to the design of biomimetic surfaces, hydrogels, and polymers that interact with carbohydrate-recognition systems.

Because "carbohydratelike" is context dependent and not a formal chemical category, its precise meaning varies by field. Researchers typically specify the features of interest, such as polyhydroxylation, ring size, or the presence of glycosidic-like linkages, when applying the term.
