What is the level of protein structure that describes all aspects of the three-dimensional folding of a polypeptide?
Primary: Simple string of amino acids called a polypeptide. Secondary: The varied hydrogen bonding of the side chains resulting in alpha helixes and beta sheets. Tertirary: The R group bondingd; hydophobic, hydrophilic, hydrogen bonding and disulfide bonding, which results in the globular, actual protein. Quarternary: The construction of multi protein subunits from tertiary structure. Such as hemeglobin.
How does the shape of a protein change as it goes from primary to quaternary?
The primary structure of a protein is the unique sequence of amino acids. There are 20 possible amino acids, and the primary structure consists of a string of amino acids held together by peptide bonds. The secondary structure occurs when the amino acid chain becomes coiled or folded in alpha helix or beta pleated sheets. The protein develops its three-dimensional shape in the tertiary structure. Van der Waals interactions, disulfide bonds, hydrophobic interactions, and ionic bonding all impact the tertiary structure. Finally, the quaternary structure is made up of more than one polypeptide chain (a polypeptide chain is the string of amino acids described in the primary structure). Hope this helps!
Properties of fibrous and globular proteins?
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!!!
Is a quaternary structure a polypeptide sequence of amino acids?
No, the polypeptide sequence of amino acids is the primary structure of a protein. The quaternary structure of the protein is the non-covalent interactions (hydrophobic binding, van der wals forces etc..) between subunits/domains of a protein.
The fibrous protein responsible for the structure of hair and wool is?
Keratin
A protein folded into a globular shape in having only one polypeptide chain has what structure?
tertiary
What type of protein is often used to carry other molecouls?
fibrous
Are enzyme typically fibrous protein?
no, they r globular proteins.
Is collagen an example of globular protein?
No, collagen is a Fibrous protein. An example would be insulin.
What are two kinds of protein?
The 2 major kinds are Globular and Fibrous
Is gravy a protein?
protein is a complex natural substance that has a globular or fibrous structure composed of linked amino acids while the gravy is a sauce made with meat juices. iv
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.

What chain is sequences of amino acids that is the foundation for the basic structure of a protein?
polypeptide chain
The primary structure of a folded protein is?
The simple polypeptide chain.
What chain is a sequence of amino acids that is the foundation for the basic structure of a protein?
polypeptide chain
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.
