WebFunctional groups are chemical motifs, or patterns of atoms, that display consistent “function” (properties and reactivity) regardless of the exact molecule they are found in. Biological molecules can contain many different types and combinations of functional groups, and a biomolecule’s particular set of groups will affect many of its ... WebChirality belongs to the discipline of stereochemistry, which is the study of the 3-dimensional structure of molecules. Chiral compounds are optically active, that means they rotate polarized light to the left or to the right depending on their configuration. The word comes from the Greek stem “chir-” meaning hand, for handedness.

Dextrorotatory … WebHowever, the only criterion for chirality is the nonsuperimposable nature of the object. A test for achirality is the presence of a mirror plane within the molecule. If a molecule has a plane within it that will cut it into two symmetrical halves, then it is achiral. Therefore, lack of such a plane indicates a molecule is chiral.

"WebA molecule which has no plane of symmetry is described as chiral. The carbon atom with the four different groups attached which causes this lack of symmetry is described as a chiral centre or as an asymmetric carbon atom . The molecule on the left above (with a plane of symmetry) is described as achiral. Only chiral molecules have optical isomers. " - How does chirality affect chemical properties

WebApr 6, 2024 · isomerism, the existence of molecules that have the same numbers of the same kinds of atoms (and hence the same formula) but differ in chemical and physical properties. The roots of the word isomer are Greek—isos plus meros, or “equal parts.” Stated colloquially, isomers are chemical compounds that have the same parts but are … WebChirality is ubiquitous in the biological world, but handedness comes unbalanced. That is, molecules of life, like sugars, proteins, and their building blocks the amino acids, appear basically in only one handedness.
