BIOMOLECULES AND ENZYMES

Detailed explanation-1: -When connected together by a series of peptide bonds, amino acids form a polypeptide, another word for protein. The polypeptide will then fold into a specific conformation depending on the interactions (dashed lines) between its amino acid side chains.

Detailed explanation-2: -A protein molecule is made from a long chain of these amino acids, each linked to its neighbor through a covalent peptide bond (Figure 3-1). Proteins are therefore also known as polypeptides.

Detailed explanation-3: -Peptides (from Ancient Greek (peptós) ‘digested’, from (péssein) ‘to digest’) are short chains of amino acids linked by peptide bonds. A polypeptide is a longer, continuous, unbranched peptide chain. Polypeptides which have a molecular weight of 10000 or more are called proteins.

Detailed explanation-4: -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.

Detailed explanation-5: -Polypeptide chains are formed by dehydration between the amino group of a L-amino acid4 with the carboxyl group of another. One hundred or more amino acids are linked together with covalent peptide bonds in various specific sequences in the polypeptide chain with polypeptide chains combining to form a protein.
