What is distinctive about primary vs secondary protein structure?
Wiki User
∙ 7y ago
The primary structure of a protein is just an amino acid string; a polypeptide.
The secondary structure of a protein is the hydrogen bonding of the side chains that form the polypeptide chain into alpha helices and beta sheets.

∙ 14y agoThe primary structure is simply the sequence of amino acids in a straight chain. For example, Lys-Val-Phe-Gly-Arg-Cys-Glu…. Would describe the beginnings of the primary structure of a protein. The secondary structure is how a straight chain of amino acids contort to become either and alpha helix, which is a "coil", or a beta-pleated sheet, which is an "Accordion" shape. Both secondary structures are held in place with hydrogen bonds.

∙ 6y agoThe primary structure is related to amino acid sequence, is the basic structure to identify a peptide or protein. On the other hand, the secondary structure refers to the interaction of electronic charges of the amino acid side chains and that are involved in protein folding mechanism.

The alpha helix and beta pleated sheet represent which level of protein structure?
The alpha helix and beta sheets are found at the Secondary level of protein folding. It's when the protein is taking its shape. Secondary structure
Is the secondary structure more polar than the linear amino acid sequence?
Protein tertiary structure is 3-D. Secondary structure is 2-D or linear. I. e. the linear a-a sequence is the secondary structure. Amino-acid monomers comprise the primary structure.
What is it called when a protein folds back onto itself?
a. tertiary structure b. primary structure c. secondary structure d. tertiary structure pick your best answer
How do you observe protein in a tissue?
PROTEINS ARE THE MACROMOLECULES COMPOSED OF AMINO ACIDS. EVERY PROTEIN HAS A PARTICULAR SEQUENCE OF THE AMINOACIDS CALLED THE PRIMARY STRUCTURE WHICH FOLDS TO PROVIDE THE PROTEIN A PARTICULAR 3D STRUCTURE. ON THIS 3D STRUCTURE LIES THE EPITOPES OR REGIONS THAT CAN BE IDENTIFIED BY THE ANTIBODIES OR IMMUNOGLOBLINS. TO VISUALIZE A PROTEIN IN A TISSUE ONE NEEDS TO HAVE PRIMARY ANTIBODY PARTICULAR TO THE PROTEIN IN QUESTION AND THE LABELED SECONDARY ANTIBODY SPECIFIC FOR THE PRIMARY ANTIBODY. ONE CAN USE FLUROSCENT MICROSCOPES TO VISUALIZE THE PROTEINS BY TAGGING THEM WITH A FLUROCHROME ON SECONDARY ANTIBODY. GAGANJOT
What is the biological effect of denaturation of proteins?
denaturation causes loss in biological activity of the protein. It does not change the primary structure of the protein but results from rearrangement of secondary and tertiary structures
Which levels of structural organization are lost when a protein is denatured?
The secondary and tertiary structures.
Differentiate the four types of protein structure?
There are four types of protein structure. These include primary structure, secondary structure, tertiary structure, and quaternary structure. Primary structure is the amino acid sequence. Secondary structure is the shape of the molecule. Tertiary structure is the interaction between groups. Quaternary structure is the interactions between protein subunits.
What are the four levels of protein structure?
primary, secondary, tertiary, and quaternary
What causes the secondary structure of protein to differ in length from the primary?
The primary structure is a one or two dimensional structure, whereas the secondary structure is a three dimensional structure in which different parts of the protein molecule bend and twist due to the formation of hydrogen bonds between atoms. This makes the secondary structure shorter than the primary structure.
What is the level of protein structure is the amino acid sequence of the protein?
Quaternary tertiary secondary primary is the sequence.
The alpha helix and beta pleated sheet represent which level of protein structure?
The alpha helix and beta sheets are found at the Secondary level of protein folding. It's when the protein is taking its shape. Secondary structure
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.
Does the secondary structure of a protein involve only the sequence of amino acids found in that protein?
While it is possible to predict likely secondary structures of a protein from its primary structure, only knowing the secondary structure, the general 3-D shape of local areas of the protein, cannot yield the primary structure.
Why protein is called primary structure?
Proteins *have* primary, secondary, tertiary, and quarternary structures. The primary structure is simply the chain of amino acids without any other structure. Secondary structure results from folding of the chain to form rudimentary structures such as alpha helices, beta sheets and turns. Tertiary structure results from the further folding of the protein with secondary structures into different 3D shapes by interactions between different parts of the secondary structure. Quarternary structure results from different proteins with tertiary structures coming together to form a protein complex.
Primary protein structure is dependent on?
Primary protein structure is the order of amino acids that compose the protein and their arrangement into 2 dimensional structures like sheets or helixes is secondary. Tertiary structure is the mixed composition of secondary forms to make a three dimension protein and quaternary structure is how the protein becomes part of a functional unit like hemoglobin inside of a blood molecule.
What aspect of protein structure are stabilized or assisted by hydrogen bonds?
secondary, tertiary, and quaternary structures, but not primary structure
Is the secondary structure more polar than the linear amino acid sequence?
Protein tertiary structure is 3-D. Secondary structure is 2-D or linear. I. e. the linear a-a sequence is the secondary structure. Amino-acid monomers comprise the primary structure.
