प्रश्न
Proteins can be classified into two types on the basis of their molecular shape i.e., fibrous proteins and globular proteins. Examples of globular proteins are:
(i) Insulin
(ii) Keratin
(iii) Albumin
(iv) Myosin
उत्तर
(i) Insulin
(iii) Albumin
Explanation:
This structure results when the chain of polypeptides coil around to give a spherical shape. These are usually soluble in water. Insulin and albumin are the common examples of globular proteins.
