Web碱性磷酸酶（alp或akp）是广泛分布于人体肝脏、骨骼、肠、肾和胎盘等组织经肝脏向胆外排出的一种酶。这种酶能催化核酸分子脱掉5’磷酸基团，从而使dna或rna片段的5’-p末端转换成5’-oh末端。 但它不是单一的酶，而是一组同工酶 [1] 。 已发现有akp1、akp2、akp3、akp4、akp5与akp6六种同功酶。 1,3-Diphenylurea is a phenylurea-type compound with the formula (PhNH)2CO (Ph = C6H5). It is a colorless solid that is prepared by transamidation of urea with aniline. DPU is a cytokinin, a type of plant hormone that induces flower development. It occurs in coconut milk. The cytokinin effect of DPU is relatively low, but other more potent phenylurea-type cytokinins have been reported.
