    • The invention relates to a ganglioside mixture, consisting of gangliosides, of the following general formula: (sugar)-OCH2—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, R1 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.
    • 本发明涉及神经节苷脂混合物,由神经节苷脂组成,具有以下通式:(糖)-OCH 2 -CH(-NH-CO-R 1)-CH(OH)-CH = CH-R 2,其中(糖)代表 糖基,基团-CO-R 1表示酰基脂肪酸,其与酰胺基分子的基团键合,R 1表示具有至少10个C原子的直链饱和烷基,R 2表示 具有至少10个C原子的直链饱和烷基或具有至少10个C原子和一个,两个或三个双键的直链烯基。 所述混合物的特征在于,至少10wt。 通式I的神经节苷脂的%为-CO-R1基团,酰基脂肪酸为C20:0脂肪酸。 所述混合物表现出改善的生物活性。
