What year was the first time in the world that insulin was synthesized by chemical methods?

China's first chemical synthesis of insulin took place in 1965, when the world's first artificially synthesized protein, bovine insulin, was born in China on September 17, 1965, which caused a huge reaction at home and abroad.

It took nearly seven years from the formal establishment of the project in December 1958 to September 1965, when scientists observed the crystallization of the artificial fully synthetic bovine insulin. This is the first time in the world to artificially synthesize a protein with the same chemical structure as the natural insulin molecule and with complete biological activity, marking a milestone leap for mankind in the journey of revealing the essence of life.

In the 1960s, China completed the artificial total synthesis of crystalline bovine insulin, relying on the self-confidence and courage to challenge the difficult problems, the rigorous scientific style, the team's sincere cooperation, and the selfless dedication of the participants. It has cultivated a group of talents for China's life sciences and laid the foundation for China's life sciences research.

The artificial synthesis of crystalline bovine insulin has opened up the era of synthetic proteins, which has had a significant impact on the development of life sciences, and also left valuable spiritual wealth for future generations, which is of great practical significance for the current accelerated implementation of the innovation-driven development strategy, and the realization of the dream of a strong science and technology country.
