pienmolekyyli

Pienmolekyyli is a term used in Finnish to describe a small molecule. In chemistry, small molecules are typically defined as organic compounds with a molecular weight of less than 900 Daltons. This size constraint is important for various applications, particularly in drug discovery, where small molecules are often favored as potential therapeutic agents. Their relatively simple structure and ability to penetrate cell membranes make them suitable for interacting with biological targets like proteins and enzymes. The term "pienmolekyyli" encompasses a vast array of chemical structures, including common substances like water and ethanol, as well as more complex compounds synthesized for specific purposes. The study of small molecules is fundamental to understanding chemical reactions, biological processes, and the development of new materials and medicines. Their synthesis, characterization, and application form a significant part of organic chemistry and medicinal chemistry research.
