General structure of an amide (specifically, a carboxamide) Formamide, the simplest amide Asparagine (zwitterionic form), an amino acid with a side chain (highlighted) containing an amide group. In organic chemistry, an amide, [1] [2] [3] also known as an organic amide or a carboxamide, is a compound with the general formula R−C(=O)−NR′R ...
Pentafluorophenyl esters produce amide bonds as effectively as succinimidyl esters and various similar agents do, but PFP esters are particularly useful because they are less susceptible to spontaneous hydrolysis during conjugation reactions.

In organic chemistry, peptide synthesis is the production of peptides, compounds where multiple amino acids are linked via amide bonds, also known as peptide bonds. Peptides are chemically synthesized by the condensation reaction of the carboxyl group of one amino acid to the amino group of another.
Structures of three kinds of amides: an organic amide (carboxamide), a sulfonamide, and a phosphoramide. In chemistry, the term amide (/ ˈ æ m aɪ d / or / ˈ æ m ɪ d / or / ˈ eɪ m aɪ d /) [1] [2] [3] is a compound with the functional group R n E(=O) x NR 2, where x is not zero, E is some element, and each R represents an organic group or hydrogen.

Poly(amidoamine), or PAMAM, is a class of dendrimer which is made of repetitively branched subunits of amide and amine functionality.PAMAM dendrimers, sometimes referred to by the trade name Starburst, have been extensively studied since their synthesis in 1985, [1] and represent the most well-characterized dendrimer family as well as the first to be commercialized. [2]
It is generally used as a carboxyl activating agent for the coupling of primary amines to yield amide bonds. While other carbodiimides like dicyclohexylcarbodiimide (DCC) or diisopropylcarbodiimide (DIC) are also employed for this purpose, EDC has the advantage that the urea byproduct formed (often challenging to remove in the case of DCC or ...
Metal amides (systematic name metal azanides) are a class of coordination compounds composed of a metal center with amide ligands of the form NR 2 −. Amido complexes of the parent amido ligand NH 2 − are rare compared to complexes with diorganylamido ligand, such as dimethylamido. Amide ligands have two electron pairs available for bonding.
Peptide bond formation via dehydration reaction. When two amino acids form a dipeptide through a peptide bond, [1] it is a type of condensation reaction. [2] In this kind of condensation, two amino acids approach each other, with the non-side chain (C1) carboxylic acid moiety of one coming near the non-side chain (N2) amino moiety of the other.
