The invention relates to a ganglioside mixture, containing of consisting of gangliosides, of the following general formula: (sugar)-OCH~2-CH(-NH-CO-R1~)-CH(OH)-CH=CH-R2~, wherein (sugar) represents a sugar radical, the group -CO-R1~ represents an acyl-fatty acid which is bonded to the radical of the molecule in the form of an amide, Rl~ represents a straight, saturated alkyl radical having at least 10 C-atoms and R2~ represents a straight, saturated alkyl radical having at least 10 C-atoms or a straight alkenyl radical having at least 10 C-atoms and one, two or three double bond(s). Said mixture is characterised in that at least 10 wt. % of the gangliosides of the general formula I are of the group -CO-R1~ and the acyl-fatty acids are a C20:0 fatty acid. Said mixtures exhibit an improved biological activity. |
