Differentiate between globular and fibrous proteins with suitable examples
Answers
Fibrous vs Globular Proteins. There are two main classes of protein tertiary structure: Fibrous proteins are generally composed of long and narrow strands and have a structural role (they are something) Globular proteins generally have a more compact and rounded shape and have functional roles (they do something)
Globular proteins are spherical in shape and consist of long chains with numerous branches and offshoots which make them great as transport proteins. Examples of fibrous proteins are collagen, elastin, keratin, silk, etc. Examples of globular protein are myoglobin, hemoglobin, casein, insulin, etc.
Explanation:
Fibrous proteins are structural proteins which are involved in the formation of bones, muscles, connective tissues, etc. Keratin and collagen are some examples of fibrous protein. Globular proteins are an important part of the biological processes in living organisms. They act as transport proteins, enzymes, hormones, etc. Some examples of globular proteins are haemoglobin, alpha immunoglobulin, beta immunoglobulin, etc.
