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!!!

∙ 11y agoFibrous proteins have an elongated structure, are insoluble and secondary structure forms the dominant structure.
Globular proteins are spheroidal, soluble and have a tertiary (sometimes Quaternary) structure.

∙ 6y agoFibrous proteins are highly elongated molecules whose secondary structures are their dominant structural motifs. We can recognize four major types of fibrous proteins:
- A Helix of helices, the most typical is the keratin, that is a mechanically durable and chemical unreactive protein that occurs in all higher vertebrates. The most common keratin is the alpha-keratin.
- A Beta pleated sheet. This fibrous protein conformation is common in instects and arachnids that produce silk to fabricate structures such as cocoons, webs, nests, and egg stalks. Most silks are made of the fibrous protein fibroin and a gummy amorphous protein called sericin that cements the fibroin fibers together.
- A Triple helical cable. Collagen, the most representative of this kind of fibrous proteins, occurs in al multicellular organisms and is the most abundant protein in vertebrates. Its an extracellular protein that is organized into insoluble fibers of great tensile strenght. For this reason is the major component of connective tissues (e.g., bones, cartilague, teeth, tendon, ligament, skin and blood vessels).
- A Nonrepetitive coil. A fibrous protein with this conformation is the elastin that has rubberlike elastic properties whose fibers can stretch to several times their normal length.
Globular proteins comprise a highly diverse group of substances that, in their native state, exist as compact spheroidal molecules. One major group of globular proteins is conformed by the enzymes. In globular proteins there are a diversity of structural elements, called supersecondary structures or motifs, e.g., beta-alpha-beta motif, beta hairpin motif, alpha-alpha motif, and beta barrels.

Is elastin globular or fibrous?
Fibrous
Globular or fibrous polypeptide chains are what type of protein structure?
Tertiary structure.
What part of the membrane would help a large protein molecule enter the cell?
Globular Proteins
What does a globular protein do in a cell membrane?
Globular proteins act as enzymes and catalyze organic reactions. They also transmit messages to regulate biological processes. Globular Proteins transport molecules through the membrane, and act as regulators within the membrane.
What is the special protein that transport oxygen?
hemoglobin
Are enzyme typically fibrous protein?
no, they r globular proteins.
Is elastin globular or fibrous?
Fibrous
What are some examples of fibrous protein?
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.
What is the difference fibrous protein and globular proteins?
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.
What proteins are in globular proteins?
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.
Which part of the membrane would help a large protein molecule enter the cell?
globular proteins .
Could a protein have what is called a globular shape?
Tritiory proteins are globular proteins. Every enzyme is a globular proteins.
What type of protein is often used to carry other molecouls?
fibrous
What are the parts of the membrane help large molecules pass through it?
Globular proteins.
What can be linked together to make proteins?
In a very basic sense, Amino Acids. One or more Polypeptides are folded into a globular or fibrous form to facilitate a biological function.
How enzymes are globular?
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.
The arrangement of a polypeptide into a fibrous or globular shape is called its?
quaternary structure
