Synthetic processes refer to methods used to create new substances by combining different elements or compounds. These processes are fundamental in various fields, including chemistry, materials science, and pharmaceuticals. For example, in the production of plastics, raw materials like petroleum are transformed through chemical reactions to form synthetic polymers. In addition to creating new materials, synthetic processes can also be used to replicate natural substances. For instance, scientists can synthesize medications that mimic the effects of naturally occurring compounds in the body. This ability to produce synthetic versions of important substances has significant implications for healthcare and industry.
