Covalent Bonds In a covalent bond, the atoms are bound by shared electrons. In a true covalent bond, the electronegativity values are the same (e.g., H2, O3), although in practice the electronegativity values just need to be close. If the electron is shared equally between the atoms formi...
Covalent Solutes Covalent solutesare molecules or compounds that have covalent bonds, where electrons are shared between atoms. The main-group elements form the majority of existing covalent molecules or compounds. Such chemicals are found everywhere: in the air we breathe, the water we drink, and...

In the event, incubation of 14C-labeled (13) and (14) with purified biotin synthase, S-adenosylmethionine, and photoreduced deazaflavin led to some covalent labeling of the protein. The extent of labeling was small (1% for the E isomer, 0.6% for the Z isomer), but it will be recalled...

From the perspective of reaction mechanism, dynamic covalent bonds can be divided into two categories: 1) traditionally reversible covalent reactions: new chemical bonds are formed in the reaction process, such as Diels-Alde reaction; 2) dynamic covalent exchange reaction: the same type of chemical...
protein with polymers containing non-ionic maleic anhydride to form covalent bonds. The patent does not teach the use of a combination of soy protein and soy carbohydrate to achieve synergistic reinforcement effects in a polymer matrix. The reaction of maleic anhydride with active hydrogen functional...
The positively charged cycloaliphatic cations (or monomers) form the 3D polymer network via covalent bonds. On the other hand, anions, do not contribute to the 3D polymer network, and are able to move freely in the polymer network. To quantify the mobility of anions in both polymer systems,...
