Proteins are informally classified into three primary groups – Fibrous proteins, globular proteins and membrane proteins. All these groups correlate with the associated tertiary structures. In this article, we shall explore the differences between globular proteins and fibrous proteins.

Structural – which means these proteins helps to maintain cell shape by providing a scaffolding |
Functional – this means globular proteins carry out a specific biological function in the body |

Frequently Asked Questions on Fibrous Protein and Globular Protein
What is the difference between fibrous proteins and globular protein?
Fibrous proteins are structural in nature, which means they help maintain cell shape by providing a scaffolding or a framework. On the other hand, globular proteins are functional, which means they carry out a specific biological function in the body.
