15-hexadecynoic acid
Alkynyl palmitic acid (aPA) is a modified palmitic acid with an ω-terminal alkyne. The terminal alkyne group can be used in a highly specific linking reaction with azide-containing reagents, known as ‘click chemistry’. The use of aPA in isolating palmitoylated proteins has been described (see References).

B、是重要的储能物质,磷脂为构成生物膜的重要成分,固醇为动物细胞膜的构成物质及形成激素等,B错误;
C、蛋白质是细胞代谢的主要结构物质,糖类是细胞代谢的主要能源物质C错误;
D、ATP的结构简式是 A-P~P~P,其中A代表腺苷,腺苷是构成ATP的重要部分,D正确.
故选:D.
第一类激素作用在靶细胞表面,并不进入细胞内部,而是与细胞膜表面特异的受体结合.这种结合使腺苷酸环化酶激活产生cAMP(一种第二信使),cAMP再去激活细胞内的一些特定系列的酶,从而引起各种生理效应.这是由E.W.Sutherland于1965年提出来的第二信使假说
第二类激素由于是脂溶性的小分子.能直接进入靶细胞,与靶细胞的细胞质中的受体分子结合成"激素-受体复合物",在一定条件下穿过核膜进入核内,与染色质上的一种酸性蛋白质相互作用,促进DNA样板转录相应的mRNA.
mRNA扩散出核膜进入细胞质,导致某种蛋白质(酶)的合成,从而引起这种激素的生理效应.
