摘要
在pH值为4.8、温度为38℃的条件下，测定了家蝇(Musca domestica L.， WHO/ in /Musca domestica /1)胸肌酸性磷酸酶的活性。以对硝基苯基磷酸(NPP)为底物。考察了酶促反应过程随时间的变化和不同底物浓度的变化。这些酶的活性在两性的成年生活过程中进行了分析:随着时间的推移，这种酶的活性在雌性中下降得更大，直到第9天。在此之后，雄性表现出更大的活动，在第15天达到最大值。在成年后的前9天内，男女的活动量下降幅度最大。
STUDY OF ACID PHOSPHATASES IN THORACIC MUSCLES OF MUSCA DOMESTICA L.
SUMMARY The activity of acid phosphatases was tested in thoracic muscles of Musca domestica L. (WHO/IN/Musca domestical/1) at pH 4.8 and at 38°C. p-nitrophenylphosphate (NPP) was used as substrate. The course of the enzymatic reaction in function with the time and in function with the different substrate concentrations was examined. The activity of these enzymes in the course of the adult life of the two sexes was analyzed: this decreases with time being greater in the females up until the 9th day. After this, the males present a greater activity which reaches its maximum point on the 15th day. The decrease in activity for both sexes is greatest within the first 9 days of adult life.
