Professor Niu Jingyi (1920-1995)
Prof. Niu was a biochemist. He was a teaching assistant of the National School of Pharmacy in Chongqing (now China Pharmaceutical University). In 1953, he received a doctorate of philosophy at University of Texas in America. When he returned to China, he worked as research fellow at Shanghai Institute of Biochemistry, and was elected academician of the Chinese Academy of Sciences in 1980.

He resolved the sequencing problem of C terminal of tobacco mosaic virus protein subunit through partial hydrazinolysis and enzymatic hydrolysis. As one of main investigators of the research, he designed the route for the artificial synthesis of crystallized bovine insulin, which made a great contribution to China’s artificial synthesis of protein with a chemical method for the first time. He also played an important role in the design of the extraction and synthesis of amino acid, peptide synthesis and the separation and disposal of the final product, and made a new achievement in the synthesis of C-peptide. He initiated the research of polypeptide synthesis in China and succeeded in synthesizing oxytocin.
