PEPTIDE BOND Meaning and
Definition
-
A peptide bond refers to a chemical bond that connects amino acids together in a chain, forming a protein molecule. It is a type of covalent bond formed between the carboxyl group of one amino acid and the amino group of another amino acid in a condensation reaction known as dehydration synthesis. This process releases a water molecule and links the two amino acids together to form the peptide bond.
Peptide bonds are crucial in the formation of polypeptides and proteins, as they create a stable backbone for the linear chains. The repetitive bonds enable the formation of a variety of structures, functional groups, and ultimately, the three-dimensional shape of proteins. Due to their strength and stability, peptide bonds are resistant to hydrolysis, allowing the formed proteins to maintain their structure under physiological conditions.
Furthermore, peptide bonds contribute to the functionality of proteins in various biological processes. The sequence and arrangement of amino acids in a peptide chain determine its unique properties and functions. Peptide bonds play a central role in protein synthesis, storage, transportation, and catalysis.
Understanding the structure and characteristics of peptide bonds has significant implications in fields such as biochemistry, molecular biology, and pharmaceutical research. It aids in studying protein folding, enzyme-substrate interactions, and designing therapeutic drugs that target specific proteins or enzymes.

Etymology of PEPTIDE BOND
The term "peptide bond" was coined in the early 20th century from the combination of two words: "peptide" and "bond".
The word "peptide" comes from the Greek word "peptós", which means "digested" or "broken down". It was first used by the German physiologist Julius Robert von Mayer in 1847 to refer to small protein fragments that could be produced by hydrolyzing larger proteins.
The word "bond" has its origins in the Old English word "bannan" or "bindan", which means "to bind" or "to tie". It has been used in various contexts to describe a connection or linkage between different entities.
Therefore, the term "peptide bond" combines the concept of smaller protein fragments (peptides) with the notion of a connection or linkage (bond) between amino acids to form a peptide chain.
