Question

Myoglobin, an oxygen carrier in muscles, consists of 153 amino acids and 70% of the polypeptide chain is in eight α helices. The protein dimensions are(45X35X25)angstrom.
Calculate (a) the volume of the protein (b) number of amino acids in the α helices (c) number of turns in α helices and (d) the overall length of α helices​

Answer 1

Answer:

The three-dimensional structures of proteins have evolved to carry out these ... The α carbon atom (Cα) of amino acids, which is adjacent to the carboxyl group, ... The size of a protein or a polypeptide is reported as its mass in daltons (a dalton ... In many α helices hydrophilic side chains extend from one side of the heli
