A polyamide is a polymer containing monomers joined by peptide bonds. They can occur both naturally, examples being proteins, such as wool and silk, and can be made artificially, examples being Nylons, Aramids, and sodium poly(aspartate).
Production from monomers
The amino group and the carboxylic acid group can be on the same monomer, or the polymer can be constituted of two different bifunctional monomers, one with two amino groups, the other with two carboxylic acid or acid chloride groups.
Aramid (pictured below) is made from two different monomers which continuously alternate to form the polymer and is an aromatic polyamide:
