no, they r globular proteins.
Examples of fibrous proteins include keratins, collagens and elastins. Fibrous proteins are only found in animals. 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 matrix and muscle fiber.
There are two class of protein based on their structure namely fibrous and globular. Globular proteins form a globe like spherical structure in contrary to rod like fibrous proteins (collagen). They are soluble in water and the structure is rendered by its three dimensional arrangement of amino acids in solution. Most of the enzymes, soluble hormones and factors fall into this class of proteins.
fibrous
Besides fibrous proteins, that have only one type of secondary structure, globular proteins, including enzymes, transport and structural proteins, some peptide hormones, and immunoglobulins, are folded structures much more compact than alpha (helices) or beta (sheets) conformations.Moreover, globular proteins, with random or repetitive conformations, have roughly spherical shapes. Globular proteins usually exhibit little or no change untill a point is reached at which there is a sudden drastic change and, invariably, a loss of biological function (e.g., structural proteins) or their enzymatic activity (for enzymes), a phenomenon known as denaturation.Finally, to understand the terciary structure of globular proteins there are two powerful techniques to do it: X-ray or neutron diffraction analysis of single crystals, and NMR analysis (Nuclear Magnetic Resonance) of small proteins in solution.
no, they r globular proteins.

Fibrous proteins are usually used to construct connective tissues, tendons, bone matrix and muscle fiber.
Fibrous proteins are proteins which are long, thin "rod" like in shape (fibres). These are insoluble. They are used for things like support and structure. E.g collagen Wheras globular proteins are relatively small and globe like, these are soluble. They have many roles e.g Enzymes, Messangers, Transporter- Haemoglobin transports oxygen to cells.

There are two main types of proteins namely; simple proteins and conjugated proteins. Simple proteins only contain amino acids while conjugated proteins contain organic and inorganic groupings in addition to amino acids.
Cytoskeleton are complex networks of fibrous protein structures have been shown to exist in the cytosol of eukaryotic cells.. These fibrous proteins helps in cellular movement that is amoeboid movement and cyclosis . They also helps the cells to maintain their shapes.
Proteins are made of chains of amino acids. All amino acids contain carbon, hydrogen, oxygen and nitrogen. They are joined by peptide links. The protein chains are then conformed either as fibrous or globular proteins.
Proteins
fibrous
In a very basic sense, Amino Acids. One or more Polypeptides are folded into a globular or fibrous form to facilitate a biological function.
Fibrous proteins are formed from the folding of beta pleated sheets and have a secondary, tertiary and quaternary structure. Globular proteins are formed from the coiling of alpha helices and have a tertiary and quaternary structure.I hope that helps!!!
