What are the four structure levels of a protein?
The four levels of protein are: 1) Primary Structure 2) Secondary Structure 3) Tertiary Structure 4) Quaternary Structure The primary structure is just the amino acids bonded to each other in a linear fashion. Secondary structure is where the alpha-helices, beta-sheets, and b-turns come into play. The tertiary structure is when a single amino acid chain forms a 3D structure. And lastly, the quaternary stuture is when 2 or more tertiary structures complex.
What are the four levels of protein structure?
primary, secondary, tertiary, and quaternary
What are the four basic levels of organization of a protein?
Levels of Protein structure: 1. Primary: refers to the unique sequence of amino acids in the protein. All proteins have a special sequence of amino acids, this sequence is derived from the cell's DNA. 2. Secondary : the coiling or bending of the polypeptide into sheets is referred to the proteins secondary structure. alpha helix or a beta pleated sheet are the basic forms of this level. They can exist separately or jointly in a protein. 3. Tertiary: The folding back of a molecule upon itself and held together by disulfide bridges and hydrogen bonds. This adds to the proteins stability. 4. Quaternary: Complex structure formed by the interaction of 2 or more polypeptide chains.
A mutation that alters a single amino acid within a protein can alter?
the primary, secondary, and tertiary level of a protein structure because once an amino acid is effected by a mutation in a single amino acid it ruins the entire protein on all levels
Why the structure of a protein so complex?
There are so many proteins because the amino acids have different R groups - which decide the Amino Acid = there are 20 amino acids. Then these amino acids are connected with peptide bonds and made into polypeptide chains. Fromt he 20 amino acids, many different combinations can be made (you still need a start amino acid at the beginning of the peptide chain and an end amino acid at the end). The combinations create the different proteins.
Which level of protein structure may be stabilized by covalent bonds?
Primary, tertiary and quaternary levels of protein structure.
Which two levels of protein structure principally determine the active site of an enzyme?
Quaternary and Tertiary levels of protein structure principally determine the active site of an enzyme.
What are the subgroups of protein?
There are four distinct levels of protein structure. The main two are primary, amino acid, secondary structure, and quaternary structure.

Which levels of structural organization are lost when a protein is denatured?
The secondary and tertiary structures.
What are the four stages of protein structures?
The four levels of protein structure are differentiated from each other by the complexity of their polypeptide chain. Proteins are constructed from 20 amino acids. The levels are the hydrogen atom, a Carboxyl group, an amino group and a variable or "R" group. They have a primary structure, the order in which the amino acids are linked to form a protein. Secondary structure , coiling and folding of the polypeptide chain. Tertiary structure, is a 3-D structure of a protein chain. Quaternary is the structure of a protein macro molecule formed by interactions between several polypeptide chains..

What is the four levels of proteins?
Proteins have primary structure, which is their amino acid sequence, secondary structure, which is either the alpha helix or the beta pleated sheet, tertiary structure, the protein's geometric shape, and quaternary structure, the arrangement of multiple protein subunits.
How many levels of protein are there?
Four levels
What levels of protein structure would be affected if all hydrogen bonding interactions were prevented?
I don't get the question, but it won't work if its hydrogen bonds are broken.
A mutation that alters a single amino acid within a protein can alter?
the primary, secondary, and tertiary level of a protein structure because once an amino acid is effected by a mutation in a single amino acid it ruins the entire protein on all levels
