22-5 What are the functions of (a) ovalbumin and (b) myosin?
(a)
Interpretation:
The functions of ovalbumin should be explained.
Concept Introduction:
An organic compound derived from two amino acids is known as dipeptide. The amino acids can be same or different. There are different ways by which amino acids can join to form a protein. The order of amino acid decides the type of protein. The bond between two amino acids to form a dipeptide is a peptide bond.
Answer to Problem 22.5P
Ovalbumin is known to be a storage protein.
Explanation of Solution
Ovalbumin is found in egg white, it makes 55% of the total protein. Its function is not known but it is assumed to be a storage protein.
(b)
Interpretation:
The functions of myosin should be explained.

Answer to Problem 22.5P
Myosin plays an important role in the contraction of muscles and processes involved in movement of one substance to other in eukaryotes.
Explanation of Solution
Myosin is ATP- dependent and plays an important role in the contraction of muscle and mobile processes in the cells of eukaryotes.
They are restricted to muscle cells but important for binding of actin, hydrolysis of ATP and force transduction.
There are myosin isoforms present in all the eukaryotic cells and they have specialized functions depending on the type of muscles they are present in.
