What does globular proteins mean?

Globular proteins or spheroproteins are spherical ("globe-like") proteins and are one of the common protein types (the others being fibrous, disordered and membrane proteins). Globular proteins are somewhat water-soluble (forming colloids in water), unlike the fibrous or membrane proteins.

What is the function of fibrous proteins?

Fibrous proteins form 'rod' or 'wire' -like shapes and are usually inert structural or storage proteins. They are generally water-insoluble. Fibrous proteins are usually used to construct connective tissues, tendons, bone and muscle fiber. Examples of fibrous proteins include keratins, collagens and elastins.

Are Microfilaments fibrous or globular proteins?

Notice that the basic building blocks of microtubules and microfilaments are globular proteins, whilst intermediate filaments are composed of fibrous units. The extracellular matrix (connective tissue), which can be thought of as the glue that holds cells together in a tissue, contains many fibrous proteins.

Are fibrous proteins tertiary structure?

Fibrous proteins, such as the keratin of your hair, contain almost exclusively primary and secondary structure, but no tertiary or quaternary structure. Examples include keratin (hair, nails) and collagen. Proteins that 'fold' into glob-like structures are known as globular proteins.
