amide (ăm`īd), organic compound formed by reaction of an acid chloride, acid anhydride, or ester with an amine. Under strong acidic conditions an amide can be hydrolyzed to yield an amine and a carboxylic acid. The reverse of this process results in the loss of water and is used in nature to link amino acids to form proteins. See amino group amino group, in chemistry, functional group that consists of a nitrogen atom attached by single bonds to hydrogen atoms, alkyl groups, aryl groups, or a combination of these three. An organic compound that contains an amino group is called an
amine. .....

Click the link for more information. . amideAny member of either of two classes of nitrogen-containing organic compounds related to ammonia and amines and containing a carbonyl group (−C=O; see functional group). The first class, covalent amides are formed by replacing the hydroxyl group (−OH) of an acid with an amino group (−NR2, in which R may represent a hydrogen atom or an organic combining group, such as methyl). Amides formed from carboxylic acids, called carboxamides, are solids except for the simplest, formamide, a liquid. They do not conduct electricity, have high boiling points, and (when liquid) are good solvents. There are no practical natural sources of simple covalent amides, but the peptides and proteins in living systems are long chains (polymers) with peptide bonds (see covalent bond), which are amide linkages. Urea is an amide with two amino groups. Commercially important covalent amides include several used as solvents; others are the sulfa drugs and nylon. The second class, ionic (salt-like) amides (see ionic bond), are made by treating a covalent amide, an amine, or ammonia with a reactive metal (e.g., sodium) and are strongly alkaline. amide 1. any organic compound containing the functional group -CONH2 2. consisting of, containing, or concerned with the group -CONH2 3. an inorganic compound having the general formula M(NH2)x, where M is a metal atom amide [′am‚īd] (organic chemistry) One of a class of organic compounds containing the CONH2radical.

No references found | Some areas investigated include homochiral porous metal-organic frameworks, transition metal complexes in delignification catalysis, metallosupramolecular complexes derived from functionalized pyridyl ligands, and coordination diversity of N-phosphorylated amides and ureas towards VIIIB group cations. Elimination of unsaturated amides is a key feature, because these materials--widely used in the closure industry--are susceptible to degradation when exposed to heat, ultra-violet light or ozone. These primary amides migrate rapidly through polyolefin films after extrusion and appear on the surface of the film to lower the COF. |
