The porphyrin compound in human body mainly includes hemoglobin, protoheme, protoporphyrin, coproporphyrin, uro-porphyrin and so on.

人体中含有卟化合物主要有血红蛋白、血红素、原卟、粪卟、尿卟等。

MNDO calculations and group theory were carried out on tetraphenyl porphyrine(TPP) to obtain its optimum molecular geometry.

运MNDO计算和群论，优化得到了较满意中位取代四苯基卟(H2TPP)构型。

A recombinant HGP44 inhibited HIV-1 replication at a 50% effective concentration of approximately 2.5 micromolar, the researchers note, somewhat less potently than did P. gingivalis extracts.

研究者重组HGP44蛋白酶在约2.5微克50%有效浓度时能抑制HIV-1复制，然而重组HGP44比直接从牙龈卟菌中提取有效性略低。
