Stereochemical shapes
網頁A recent version of the previously named shape theory, also known as odotope theory or Weak Shape Theory, holds that a combination of activated receptors is responsible for any one smell, as opposed to the older model of one receptor, one shape, one smell. 網頁The shape of molecules is super important to life as we know it. In this episode of Crash Course Organic Chemistry we’re learning about stereochemistry and how to identify …

Stereochemistry, a subdiscipline of chemistry, involves the study of the relative spatial arrangement of atoms that form the structure of molecules and their manipulation. The study of stereochemistry focuses on the relationships between stereoisomers, which by definition have the same molecular … 查看更多內容 It was not until after the observations of certain molecular phenomena that stereochemical principles were developed.
