Peptide bond. In organic chemistry, a peptide bond is an amide type of covalent chemical bond linking two consecutive alpha-amino acids from C1 (carbon number one) of one alpha-amino acid and N2 (nitrogen number two) of another, along a peptide or protein chain.
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.
In organic chemistry, an amide, [1] [2] [3] ... The amide group is called a peptide bond when it is part of the main chain of a protein, ...
A neuropeptide is a peptide that is active in association with neural tissue. A lipopeptide is a peptide that has a lipid connected to it, and pepducins are lipopeptides that interact with GPCRs. A peptide hormone is a peptide that acts as a hormone. A proteose is a mixture of peptides produced by the hydrolysis of proteins. The term is ...
The Bailey peptide synthesis is a name reaction in organic chemistry developed 1949 by J. L. Bailey. [1] [2] It is a method for the synthesis of a peptide from α-amino acid-N-carboxylic acid anhydrides (NCAs) and amino acids or peptide esters. [2] [3] The reaction is characterized by short reaction times and a high yield of the target peptide. [2]
Chemical ligation of unprotected peptides is enabled by formation of an unnatural moiety, i.e. non-peptide bond, linking the two peptide segments in the ligation product. It was envisioned as a general method that would greatly simplify the chemical synthesis of protein molecules and enable the application of the entire repertoire of chemistry ...

When proline is bound as an amide in a peptide bond, its nitrogen is not bound to any hydrogen, meaning it cannot act as a hydrogen bond donor, but can be a hydrogen bond acceptor. Peptide bond formation with incoming Pro-tRNA Pro in the ribosome is considerably slower than with any other tRNAs, which is a general feature of N-alkylamino acids ...
