In their molecular groundstate structures, determined by X-ray diffraction, the lone pair on the phosphano P atom prefers the syn position with respect to the ylidic PC bond. An unusual lengthening of the sp2-CC bond [1.553 (4) (10a), 1.543 (6) (10b), 1.551 (4) (10c)] to values...
The property of a substance/matter is lost when a molecule breaks. The breakdown of a molecule results in individual atoms that have different chemical and physical properties than the molecule. NOTE IT! Molecules can acquire distinct shapes ormolecular structureslike, linear, V-shaped, trigonal pl...
Learn what is a protein molecule and what is involved at each level of protein molecular structure. Also see protein molecule examples and their...
The problems of the mechanism of enzymatic activity can be studied on the basis of the course of affinity chromatography or the molecular structures of—for example, fibroblast or leucocyte interferons can be judged. The application of immunosorbents in solid-phase radioassay and in immunofluorescence...

hydrogen serves as a bridge between two atoms. Similar to a covalent bond, the hydrogen bond is a common chemical bond inorganic compounds, particularly nucleic acids and proteins. The hydrogen bond is responsible for the formation of secondary and tertiary structures of nucleic acids and proteins....
