A lipid represented by the following formula: MO--(CO--CH.sub.2 --NH).sub.p --CO--(CH.sub.2).sub.n --CO--(NH--CH.sub.2 --CO).sub.q --OM wherein M represents a hydrogen atom or an alkali metal, n is an integer of 6-18 and p and q each represent an integer of at least 1 with the proviso that a total of p and q is not greater than 6. When an aqueous solution of an alkali metal salt of the lipid is allowed to stand for 2-3 weeks, a fibrous microtube including a tubular body having a diameter of 1-3 .mu.m and a plurality of spherical vesicles contained within the tubular body and having a diameter of 0.1-3 .mu.m is formed.
以下是化学式表示的脂质:MO--(CO--CH.sub.2 --NH).sub.p --CO--(CH.sub.2).sub.n --CO--(NH--CH.sub.2 --CO).sub.q --OM,其中M代表氢原子或碱金属,n为6-18的整数,p和q各代表至少1的整数,但p和q的总和不大于6。当碱金属盐的水溶液静置2-3周时,形成了一根纤维状微管,包括一个直径为1-3μm的管状体和多个直径为0.1-3μm的球形囊泡包含在管状体内。
