- HOME BIOLOGY DEFINITION. Peptide bond. A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H 2 O). This is a dehydration synthesis reaction, and usually occurs between amino acids.

- Peptides are polymers of amino acids. A tripeptide contains three amino acid residues. Peptide bonds are ester linkages. Peptide bonds form from nucleophilic attack by an alpha-carboxyl carbon atom on an electron pair of an alpha-amino nitrogen atom of another amino acid.

peptide A peptide is a short chain of amino acids. The amino acids in a peptide are connected to one another in a sequence by bonds called peptide bonds.Typically, peptides are distinguished from proteins by their shorter length, although the cut-off number of amino acids for defining a peptide and protein can be arbitrary.eptides are generally considered to be short chains of two or more amino acids. Meanwhile, proteins are long molecules made up of multiple peptide subunits, and are also known as polypeptides. Proteins can be digested by enzymes (other proteins) into short peptide fragments.

Types of Chemical Bonds in Proteins The primary structure of a protein consists of amino acids chained to each other. Amino acids are joined by peptide bonds. A peptide bond is a type of covalent bond between the carboxyl group of one amino acid and the amino group of another amino acid. Amino acids themselves are made of atoms joined together by covalent bonds.

An Introduction to Molecular Biology/Function and structure of Proteins Proteins are biopolymers of acids, so named because the amino group is bondedto the carbon atom, next to the carbonyl group. The physical and chemical propertiesof a protein are determined by its constituent amino acids. The individual amino acidsubunits are joined by amide linkages called peptide bonds.

- Peptide bond - Synthesis. 1  When two amino acids form a dipeptide through a peptide bond it is called condensation. In condensation, two amino acids approach each other, with the acid moiety of one coming near the amino moiety of the other. One loses a hydrogen and oxygen from its carboxyl group (COOH) and the other loses a hydrogen from its amino group (NH2).

How do peptide bonds form? A series of amino acids joined by peptide bonds form a polypeptide chain, and each amino acid unit in a polypeptide is called a residue. A polypeptide chain has polarity because its ends are different, with an a-amino group at one end and an a-carboxyl group at the other. peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O).

- The peptide bond has a number of characteristics that are critical in determining how polypeptides behave. Although drawn as a single bond, the peptide bond behaves more like a double bond. While there is free rotation around a single bond, rotation around a peptide bond is constrained.he peptide bond has a number of characteristics that are critical in determining how polypeptides behave.

Peptide Peptides (from Gr.: πεπτός, peptós digested; derived from πέσσειν, péssein to digest) are biologically occurring short chains of amino acid monomers linked by peptide (amide) bonds. The covalent chemical bonds are formed when the carboxyl group of one amino acid reacts with the amine group of another. The shortest peptides are dipeptides, consisting of 2 amino acids joined by a single peptide bond, followed by tripeptides, tetrapeptides, etc. A polypeptide is a long, continuous, and unbranched peptide chain.

An Introduction to Molecular Biology/Function and structure of Proteins The resulting group of atoms, which hold the amino acids together, is called a peptide bond. Any of the 20 different amino acids can occur in any position along a polypeptide chain. This means that there is a very large number of possible chains, even at lengths of only a few amino acids.
