Definition of Globular Proteins
The proteins are classified into two classes based on their structure i.e. fibrous and globular. Globular proteins are defined as proteins that have a more compact structure as compared to fibrous. They are usually round or spherical. They play a lot many functions in a cell. There is an irregular sequence of amino acids in their structure. They are extremely sensitive to physical changes such as pH, temperature, etc. They are generally soluble in water and exhibit a tertiary level of structure. They are non-elastic.
Example of Globular Proteins:
Examples of globular proteins include enzymes, haemoglobin, immunoglobulins, etc.
