An organic substance that contains an >NH group attached to two carbon-containing groups of varying complexity is called a secondary amine, and one in which three carbon-containing groups are attached to a nitrogen atom is called a tertiary amine. In all the cases, the lone pair of electrons...
The resulting covalent bonds between the epoxy resin's epoxy groups and the hardener's amine groups allow the polymer to cross-link, impacting the epoxy's rigidity and strength. By adjusting curing conditions like temperature and choosing specific resins and hardeners, it is possible to customize ...
An O-glycosidic bond is formed when the anomeric carbon of the sugar establishes a link with the oxygen atom in the hydroxyl group of the alcohol. If the anomeric carbon of the sugar makes the link with the nitrogen atom of an amine, the bond is referred to as an N-glycosidic bond. ...
Common alpha-blockers include non-selective options like phenoxybenzamine and selective A1 blockers like alfuzosin, doxazosin, prazosin, silodosin, tamsulosin, and terazosin. Who can take alpha-blockers? Alpha-blockers are suitable for individuals with hypertension, benign prostatic hyperplasia (BPH...
Each alpha-helix is stabilized by hydrogen bonding between the amine and carbonyl groups on the same polypeptide chain. The beta-pleated sheet is stabilized by hydrogen bonds between the amine groups of one polypeptide chain and carbonyl groups on a second adjacent chain. ...
They are formed by the reaction of epichlorohydrin with an amine. The aromatic amines are suitable for high-temperature applications. The most important resin in this class is tetraglycidyl methylene dianiline (TGMDA) that offers: excellent mechanical properties, high glass transition temperatures, an...
These complex topologies, formed mainly of spiro-5 rings and new cage types, also include some of the most structurally complex zeotypes discovered. A comprehen- sive investigation of beryllium–arsenate and beryllium–phosphate framework chemistry was undertaken using a variety of amine tem- plates ...
The carbonyl group is composed of two carbon atoms that are double bonded to an oxygen atom. The amine group, in which a nitrogen atom shares a single bond with R groups, is the second. R groups can be regarded of as substituents for other atoms or molecules in a structure. ...
