早已肯定血液中有两种胆碱酯酶,一种存在于血清中,另一种结合于红细胞膜上,称为红细胞胆碱酯酶,或“真正的”胆碱酯酶。它对乙酰胆碱具有更高的选择性,能催化乙酰胆碱水解为胆碱和乙酸。该酶对红细胞的作用尚不明。根据对神经细胞胆碱酯酶的研究,推测可影响红细胞膜的通透性,然而尚未确定红细胞上酶作用物的位置所在。 It has long been known that there are two cholinesterases in the blood, one in the serum and the other in the erythrocyte membrane, known as erythrocyte cholinesterase, or “real” cholinesterase. It has a higher selectivity for acetylcholine, acetylcholine can catalyze the hydrolysis of choline and acetic acid. The role of this enzyme on erythrocytes is not known. According to the study of neural cells cholinesterase, presumably affect the permeability of the erythrocyte membrane, however, the location of the enzyme on erythrocytes has not yet been determined.
