peptide bonds

A peptide bond is a connection that links amino acids, the building blocks of proteins. When one amino acid joins another, a peptide bond forms through a chemical reaction that removes a small molecule called water. This bond creates a stable link, allowing amino acids to form long chains that fold into specific shapes to carry out various functions in the body. In essence, peptide bonds are the glue that holds amino acids together to build proteins, essential molecules for life processes.
