Abstract : in ureide - transporting legumes , ureides ( allantoin and allantoic acid ) are major transportform of biological fixed nitrogen . the distribution , properties , structure and regulation of plant allantoinase were reviewed in detail . the advances in the recent studies on allantoate amidohydrolase and ureidoglycolate amidohydrolase were introduced . and the works desired to be done were pointed out 文摘:全面綜述植物酰脲降解代謝酶的研究現況,概述植物尿囊素酶的分布、性質、結構,以及調節控制,并簡介植物尿囊酸酰胺水解酶和脲基乙醇酸酰胺水解酶的研究近況,同時指出待研究的方向。

Furbenicillin sodium , a known semi - synthetic ureide type of antibiotic firstly marketed in china , was synthesized from starting material 2 - furaldehyde via six steps including oximation reaction , beckmann rearrangement , isocyannuration , amination , condensation and salification etc 摘要以呋喃甲醛為起始原料,經厲化、貝克曼重排、異氰脲酸化、氨基化、縮合和成鹽6步反應,合成了酰脲類青霉素抗生素呋布西林鈉。
