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: -Proteins are formed from one or more polypeptides joined together. Hence, proteins essentially are very large peptides.

Detailed explanation-3: -Polypeptide vs Protein: at this point, the polypeptide structure is called a protein because it has formed a functional conformation. Hydrophobic bonds – side chains that are non-polar and the hydrophobic groups together.

Detailed explanation-4: -Polypeptides. Polypeptides help make up proteins by bonding numerous amino acids together. Proteins are created by the bonding of two or more polypeptides, which are then folded into a specific shape for a particular protein.

Detailed explanation-5: -Technically, a polypeptide is a string of covalently bonded amino acids which are not folded into any specific structure-whereas a protein is a string of covalently bonded amino acids that has folded into its correct shape.
