Primary structure of a protein represents the sequence of the amino acids of that particular protein. The amino acids are bonded together by a bond called 'peptide bond'. The peptide bond is formed by carbonyl group of an amino acid with nitrogen group of the adjacent amino acid. Only this peptide bond is responsible for the formation of primary structure of protein. Hence the ionic bonds are not involved in the primary structures of protein.
No, ionic bonds are not responsible for the primary structure of a protein. The primary structure of a protein is determined by the sequence of amino acids linked by peptide bonds. Ionic bonds may play a role in stabilizing the secondary or tertiary structures of proteins.

Which level of protein structure may be stabilized by covalent bonds?
The primary level of protein structure can be stabilized by covalent bonds. For example, disulfide bonds form between cysteine amino acids to help stabilize the primary structure of a protein.
What type of bond joins monomers in a primary structure?
A peptide bond joins amino acids in a primary structure of a protein. It forms between the carboxyl group of one amino acid and the amino group of another amino acid, resulting in a covalent bond.
What type of bonds are there for the four different type of protein structure?
The four different types of protein structures are determined by the interactions between amino acid residues in the polypeptide chain. These structures are held together by different types of bonds: primary structure by peptide bonds, secondary structure by hydrogen bonds, tertiary structure by disulfide bonds, hydrogen bonds, ionic bonds, and hydrophobic interactions, and quaternary structure by the same bonds as tertiary structure.
Does the secondary structure of a protein involve only the sequence of amino acids found in that protein?
No, the secondary structure of a protein is determined by the hydrogen bonds between amino acids in the polypeptide chain. These interactions lead to the formation of regular structures like alpha helices and beta sheets. The primary structure, which is the sequence of amino acids, plays a role in determining the secondary structure.
What bonds are disrupted when a protein is denatured?
Non-covalent bonds such as hydrogen bonds, van der Waals interactions, ionic bonds, and hydrophobic interactions are disrupted when a protein is denatured. These bonds are responsible for maintaining the protein's specific three-dimensional structure and functionality.

How does protein denatured?
It breaks the hydrogen bonds and hydrophobic interactions between different parts of the protein molecule. Proteins are composed of amino acid subunits linked together by peptide bonds—this is called a polypeptide and is also known as the primary structure of a protein. The primary structure interacts with itself (also known as folding) forming hydrogen bonds and hydrophobic interactions with different parts of the same molecule. Heat disrupts the hydrogen bonds and hydrophobic interactions leaving the protein to unfold when it is heated. Since heat is not strong enough to break the peptide bonds between the amino acid subunits, the primary structure remains intact. Once the protein is cooled again, the hydrogen bonds and hydrophobic interactions can reform since they are based on the makeup of the primary structure and it hasn't changed. :) Hope this helps.
What level of protein structure is stablized by covalent bonds?
The primary structure of a protein is stabilized by covalent bonds, specifically peptide bonds that link amino acids together in a linear chain. This primary structure sets the foundation for higher levels of protein structure such as secondary, tertiary, and quaternary structures.
Which level of protein structure consist of a simple strand of amino acids?
The primary structure of a protein consists of a simple linear sequence of amino acids linked by peptide bonds. This level of structure is determined by the specific order of amino acids in the polypeptide chain.
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.
The primary structure of a folded protein is?
The primary structure of a folded protein is the linear sequence of amino acids linked together by peptide bonds. This sequence is derived from the protein's genetic information and serves as the foundation for its three-dimensional shape and function.
What is a primary protein structure formed by?
A primary protein structure is formed by a linear sequence of amino acids linked together by peptide bonds. This sequence is determined by the genetic information encoded in DNA.
What is the teritary structure of a protein?
The tertiary structure of a protein is just how a polypeptide folds up into a "glob" or a "pretzel-like" shape. Primary structure determines secondary and tertiary structure of a protein. Usually a tertiary protein is held together Disulfide bonds like those found in a Cysteine residue.
Does the secondary structure of a protein involve only the sequence of amino acids found in that protein?
No, the secondary structure of a protein is determined by the hydrogen bonds between amino acids in the polypeptide chain. These interactions lead to the formation of regular structures like alpha helices and beta sheets. The primary structure, which is the sequence of amino acids, plays a role in determining the secondary structure.
