- 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 (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.

Peptides The peptide bond is the single most important covalent bond linking amino acids in peptides and proteins. The only other type of covalent bond that occurs frequently enough to deserve special mention here is the disulfide bond sometimes formed between two cysteine residues.

- Peptides and polypeptides are amino acid chains of various lengths. A peptide contains two or more amino acids, and a polypeptide, on the other hand, contains ten or more amino acids.Peptide bonds hold together both peptides and polypeptides.eptides and polypeptides are both proteins, but biochemists do not generally describe peptides and polypeptides using the generic term protein. Further, biochemists normally only use the word protein when referring to large peptide molecules.

Peptide Peptides (from Gr. πεπτός, digested, derived from πέσσειν, 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 amino group of another. The shortest peptides are dipeptides, consisting of 2 amino acids joined by a single peptide bond, followed by tripeptides, tetrapeptides, etc.

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.

The Role of Ribosomes and Peptide Bonds in Genetic Translation For this reason, we often use the word polypeptide to describe an amino acid chain. A polypeptide is a chain of amino acids linked together by peptide bonds. 'Poly' means 'many,' just like in the word 'polymer,' and 'peptide' refers to a peptide bond, so a molecule with many peptide bonds is called a polypeptide.If a polypeptide is the final product that we get from translation, then the peptide bonds are like the mixing of the ingredients in our skillet.t's made of ribosomal RNA, or rRNA, and protein. Ribosomes are located on the rough endoplasmic reticulum, or RER, that surrounds a cell's nucleus. In fact, ribosomes are the reason that the RER is called rough; they give the endoplasmic reticulum a rough appearance when viewed under a microscope.

Enzyme Catalysis: The Serine Proteases Although the hydrolysis of a peptide bond is energetically downhill, this process is very slow at normal temperature and pH. A group of chemists measured this rate, and found that a simple peptide bond between two amino acids in water and room temperature has a half-life of several years. (Kahne & Still 1988) For example, hair and wool, which are composed almost entirely of protein, can remain in water for weeks and not break down.
