#nylon

• Adipic — Relating to fat, of the nature of fat, or derived from it; in organic chemistry, the structural term specifically defines adipic acid (hexanedioic acid), a saturated dicarboxylic acid widely used at an industrial level as a fundamental raw material in the synthesis of nylon, polyurethanes, and plasticizers.
• Amide — An organic compound functionally derived from a carboxylic acid where the hydroxyl group (-OH) has been replaced by an amino group (-NH2, -NHR, or -NR2), having the general structural formula R-CO-NR2. Amides are fundamental in nature and industry, forming the peptide bonds that link amino acids into proteins and synthetic polymers like nylon, characterized by high chemical stability due to the conjugation of electrons from the nitrogen atom with the carbonyl group.
