What are the key differences between fibrous and globular proteins? I know an example of each (haemoglobin and collagen) but don't know the differences in the structure and uses. The textbook is of course no help!! Haha :)
fibrous proteins - their function in cells and organelles is usually structural. Collagen is an example. its fibres are insoluble, inelastic, and have high tensile strength. this makes collagen an ideal material for tendons and ligaments which must withstand large pulling forces.
