溶酶体广泛存在于动物组织细胞内,在膜系统发育上它比线粒体更古老。用Giemsa或Toluidine染色时,白细胞内的颗粒是典型的溶酶体,这种细胞器的一个显著特性是:在由单位膜包围成的囊状结构中充满着各种各样的酸性水解酶,包括蛋白质、糖及脂类的水解酶。溶酶体中的酶,除酸性水解酶外,其他特异酶也已被鉴定出来。除酶外,还有其他活性物质。溶酶体内的水解酶已发现的有40种以上,它们是:β—半 Lysosomes are widely present in animal tissue cells and are more ancient than mitochondria in membrane system development. Particles of leukocytes are typically lysosomes when stained with Giemsa or Toluidine. One notable feature of such organelles is that the cystic structure surrounded by the unit membranes is filled with a variety of acidic hydrolases, including Proteins, carbohydrates and lipids hydrolases. Enzymes in lysosomes, in addition to acid hydrolases, other specific enzymes have also been identified. In addition to enzymes, there are other active substances. Over 40 lysogens have been found in lysosomal hydrolases, which are: beta-half
