BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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. Each type of protein has a unique sequence of amino acids, exactly the same from one molecule to the next.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -Each polypeptide chain is made up of smaller subunits or amino acids bonded together. Polypeptides are the building blocks of proteins, and amino acids are the building units of polypeptides.

Detailed explanation-5: -A peptide is two or more amino acids joined together by peptide bonds, and a polypeptide is a chain of many amino acids. A protein contains one or more polypeptides. Therefore, proteins are long chains of amino acids held together by peptide bonds.
