Bioretrosynthesis is a term used to describe the process of using biological systems to break down molecules into simpler compounds. It is a popular research area for the development of more sustainable and eco-friendly methods of producing useful chemicals. Some of the synonyms for bioretrosynthesis include biocatalysis, biosynthesis, and biotransformation. Biocatalysis refers to the use of biological catalysts, such as enzymes, to catalyze chemical reactions. Biosynthesis, on the other hand, is the process of using living organisms to produce complex compounds. Biotransformation is the conversion of one compound into another by living organisms. All of these synonyms are related to the use of biological systems to produce valuable chemicals and find important applications in various branches of science and industry.
