They may be soluble ( those in egg yolk and Blood plasma) or insoluble ( those in cell membranes) in water and water solutions. 有的可以溶解于水和水溶液(在蛋黄和血浆中的)有的则不能溶解(在细胞膜中的)。
After 1  ̄ 8 h of anthesis, the egg cell has no wall at its chalazal end and a space is present between the plasma membranes of the egg cell and central cell which are discontinuous. 开花后1~8h,卵细胞合点端无壁,其质膜和中央细胞质膜之间有较宽间隙,两质膜均有间断处。
Distribution of the tributyltin ( TBT) between egg phosphatidylcholine membranes ( liposome) and water under different pH and a comparison between the partition of TBT into lipid membranes and into octanol were studied. 测定了不同酸度条件下三丁基锡(TBT)的正辛醇水分配系数,并用卵磷脂自行制备脂质体代替正辛醇研究了TBT在人工合成生物膜水间的分配行为。
Mammalian fertilization consists of an intricate cascade of cell-cell interactions that culminate in the fusion of sperm and egg membranes and formation of a zygote. 哺乳动物受精是由一系列复杂有序的步骤组成的细胞相互作用过程,最终导致精卵质膜融合形成受精卵。
