Oparin was born in
Uglich in 1894 into a merchant family. He and his parents soon moved to Kokayevo, a nearby village. Oparin had an older brother, , who became an economist. Oparin graduated from the
Moscow State University in 1917 and became a professor of biochemistry there in 1927. Many of his early papers were about plant enzymes and their role in
metabolism. His first experimental studies were devoted to the chemistry of respiration. In them, he showed that chlorogenic acid is an essential component of redox reactions in the cell. In 1924 he put forward a hypothesis suggesting that
life on Earth developed through a gradual
chemical evolution of
carbon-based
molecules in
the Earth's primordial soup. In 1935, along with academician
Aleksei Bach, he founded the Biochemistry Institute of the
Soviet Academy of Sciences. However, according to cytologist : From 1942 to 1960, Oparin headed the Department of Plant Biochemistry at Moscow State University, where he gave lectures on general biochemistry, technical biochemistry, and special courses on enzymology and the problem of the origin of life. Oparin died in Moscow on 21 April 1980, and was interred in
Novodevichy Cemetery in Moscow. Oparin became
Hero of Socialist Labour in 1969, received the
Lenin Prize in 1974, and was awarded the
Lomonosov Gold Medal in 1979 "for outstanding achievements in biochemistry". He was also a five-time recipient of the
Order of Lenin. ==Theory of the origin of life==
