Primary structure of protein :
- the sequence of amino acids in a polypeptide chain.
- it read from the N-terminal end to the C-terminalend.
important structure cause it will determine the 3-d structure of protein.
Example of effects of changes in primary structure:
Sickle-cell anemia
amino acid substitution will cause mulfunctioning protein.

Is collagen a secondary or tertiary structure?
Collagen is a primary protein structure, composed of three polypeptide chains that form a unique triple helical structure. This triple helical structure is considered the primary structure of collagen.
Define primary structure and describe how it may be deduced in the laboratory?
The primary structure is the formation of the amino acid sequence within a protein. It can be deduced in a laboratory by hydrolyzing the protein into small peptide chains, dehydrolyzing the protein into small peptide chains, determining their amino acid sequences, and then overlapping the sequences of small fragments created with different agents to reconstruct the whole polypeptide.
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.
Do proteins have hydrogen bonds?
Yes, proteins can form hydrogen bonds between their amino acid residues. These hydrogen bonds contribute to the overall structure and stability of proteins, influencing their folding and interactions with other molecules.
What aspect of protein structure are stabilized or assisted by hydrogen bonds?
secondary, tertiary, and quaternary structures, but not primary structure
Is the structure of protein primary?
The primary structure of proteins is simply a peptide (chain of amino acids).
Which element is NOT characteristic of the primary structure of proteins?
The primary structure of proteins is characterized by the linear sequence of amino acids. Therefore, the presence or absence of specific chemical bonds (like disulfide bonds) is not a defining feature of the primary structure.
What structure of proteins are the sequence of amino acids known as?
That's the primary structure.
Can you sequence the proteins?
Yes; by their primary structure of amino acids.
What are primary proteins?
There is not something known called primary proteins. But proteins do have primary structure. Poly peptide chains after synthesized from ribosomes make up primary structure of a protein. this will afterward form 2D and 3D structure with additional structures and interactions.
What role do bonds play in the primary structure of proteins?
Bonds in the primary structure of proteins, like peptide bonds, hold amino acids together in a specific sequence, forming the backbone of the protein chain. These bonds are crucial for determining the overall structure and function of the protein.
How are proteins distugushed from each other?
They have different primary, secondary, tertiary, and quaternary structure.
What has the author Walter A Schroeder written?
Walter A. Schroeder has written: 'The primary structure of proteins'
What is the bond that exists within proteins?
The atoms of proteins are bond with covalent bonds. The type of bonds participated in making the primary structure of proteins are peptide bonds. Proteins are natural polymers.
Do you expect proteins in urine to be in primary secondary and tertiary structures?
Proteins in urine are typically in their primary structure, which is the linear sequence of amino acids. Secondary and tertiary structures may be disrupted due to the conditions in the urinary tract. Significant alterations in structure can indicate health issues such as kidney damage or proteinuria.
Is collagen a secondary or tertiary structure?
Collagen is a primary protein structure, composed of three polypeptide chains that form a unique triple helical structure. This triple helical structure is considered the primary structure of collagen.
Is it true that proteins at the inner surface of the plasma membrane attach the membrane to the cells support structure making the cell rigid?
The primary proteins of cellular structure (such as in microfilaments or intermediate tubules) is myosin and actin, and sometimes collagen, and all of these are proteins in the cell. Because proteins generally connect to similar structures (aka other proteins), and the cellular membrane must SOMEHOW be attached to the primary cell structure, and it is easier to connect to the inner membrane than outer, the answer is yes.
