Concept explainers
To determine: Whether the red α-helix is right handed or left handed.
Introduction: A long chain of amino acids is known as protein. The ordered arrangement of the amino acids in localized regions of a polypeptide chain form secondary structure. α-helix and β-sheet are the two main secondary structures of proteins.
To determine: Whether the β-sheets are parallel or anti-parallel.
Introduction: The secondary structure of protein contains α-Helices and β-Sheets. Beta sheets are the secondary structure of proteins. There are two types of beta sheets; the parallel and anti-parallel.
To determine: Whether there is any knot in the polypeptide chain.
Introduction: Proteins are biological macromolecules consisting of polypeptide chains. Amino acids serve as the building blocks of the polypeptides.
To determine: The reason why there is no any knot in the polypeptide chain.
Introduction: The protein consists of one or more polypeptide chains. Each polypeptide chain consists of smaller sub-units or amino acids that are linked together.
