What type of bond connects amino acids in a protein?

Amino acids in a protein are connected by peptide bonds. A peptide bond is a specific type of covalent bond formed between the carboxyl group of one amino acid and the amino group of another, resulting in the release of a water molecule through a condensation reaction. This bond is crucial as it links amino acids together in a linear chain, creating a polypeptide, which ultimately folds into a functional protein.

Peptide bonds play a fundamental role in the structure and function of proteins. The sequence and number of amino acids linked by these bonds determine the protein's unique properties, influencing its shape and biological function. Understanding the nature of peptide bonds is essential for grasping how proteins are synthesized and how they function within living organisms.
