Presents novel hollow fiber shaped organic nanotubes that can be easily produced in a short time span and also have a broad range of utility. An N-glycoside type glycolipid represented by the general formula (1) shown below.G-NHCO&#x2014;R&#x2003;&#x2003;(1)(In the formula, G represents a saccharide radical other than a hemiacetal hydroxyl group bonded to the anomer carbon atom of the saccharide, and R represents an unsaturated hydrocarbon group containing ten to 39 carbon atoms.) This molecule self-aggregates and forms hollow fiber shaped organic nanotubes in water when this N-glycoside type glycolipid is dissolved, allowed to cool gradually and allowed to stand undisturbed at room temperature. The average external diameter of the nanotubes is from 70 nm to 500 nm and the average internal diameter (average diameter of the cavity) is from 40 nm to 300 nm.

N-glycoside type glycolipids and hollow fiber type organic nanotubes made of the same

A gelatinizer having gel-forming capability in both organic solvents and water, is provided. The hydrogelatinizer is represented by:(where, A is a sugar residue, and R is an alkyl group).
