| GENERAL DESCRIPTION OF AMIDE | ||
| Amide is a group of organic chemicals with the general formula RCO-NH2 such as acetamide, where 'R' groups range from hydrogen to various linear and ring structures or a compound with a metal replacing hydrogen in ammonia such as sodium amide, NaNH2. Amide is formed from of ammonia (NH3) and a carboxylic acid in which a carbon atom is solid bonded to oxygen and also to an hydroxyl group or by reaction of an acid chloride, acid anhydride, or ester with an amine. An amide is 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, the secondary structure of which is due in part to the hydrogen bonding abilities of amides. Sulfonamides are analogs of amides in which the atom solid bonded to oxygen is sulfur rather than carbon. Polyamide is a polymer containing repeated amide groups, as in various kinds of nylon and polyacrylamides. | ||
