What else can I help you with?
Chitinase is an enzyme that breaks down the chitin molecules in an insect's exoskeleton The sequence of amino acids in the chitinase is an example of which level of protein structure?
The sequence of amino acids in chitinase represents the primary structure of the protein. This refers to the linear order of amino acids in the polypeptide chain.
The structural level of a protein least affected by a disruption in hydrogen bonding is the?
The primary structure of a protein is least affected by a disruption in hydrogen bonding. This is because hydrogen bonding primarily stabilizes secondary and tertiary structures like alpha helices and beta sheets, while the primary structure is dependent on the sequence of amino acids.
What would happen to a protein if the gene was changed DNA?
If a gene encoding a protein is altered at the DNA level, it can result in a change in the protein's amino acid sequence. This alteration can lead to changes in the protein's structure and function, potentially affecting its ability to interact with other molecules and carry out its normal physiological roles.
What makes two proteins different from each other?
proteins are made out of 20 different amino acids, (like tiny balls make up a collar) depending on the cuantity of each, different types of protein are made. you can have a look at what are proteins on : www.kidshealth.com and type proteins.
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.
What is the Primary level of a protein structure?
The primary level of protein structure refers to the linear sequence of amino acids in a protein chain. It is the simplest level of protein structure and is determined by the specific order of amino acids encoded by the DNA sequence.
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.
Chitinase is an enzyme that breaks down the chitin molecules in an insect's exoskeleton The sequence of amino acids in the chitinase is an example of which level of protein structure?
The sequence of amino acids in chitinase represents the primary structure of the protein. This refers to the linear order of amino acids in the polypeptide chain.
What The first level of organization of a protein is created by a linear sequence?
The first level of organization of a protein is known as its primary structure, which is determined by the linear sequence of amino acids linked together by peptide bonds. This sequence dictates the protein's unique characteristics and ultimately influences its folding and function. The primary structure is critical, as even a single change in the sequence can significantly impact the protein's stability and activity.
Define primary structure of proteins?
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 anemiaamino acid substitution will cause mulfunctioning protein.
What occurs in the tertiary but not primary structure of protein?
In protein structure, tertiary structure refers to the overall three-dimensional folding of a polypeptide chain, which is stabilized by various interactions such as hydrogen bonds, ionic bonds, hydrophobic interactions, and disulfide bridges. This level of structure is crucial for the protein's functionality and is not present in primary structure, which is merely the linear sequence of amino acids. While primary structure defines the sequence, tertiary structure determines how that sequence folds into a functional shape.
What is the primary level of the protein structure?
Just the polypeptide chain of amino acids.
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.
What are four levels of protein structer and the basis of each?
Primary structure: This is the linear sequence of amino acids in a protein, determined by the genetic code. Secondary structure: This refers to the local folded structures within a protein, such as alpha helices and beta sheets, stabilized by hydrogen bonding between amino acids. Tertiary structure: This is the three-dimensional arrangement of the entire protein molecule, driven by interactions between side chains of amino acids, including disulfide bonds, hydrogen bonds, and hydrophobic interactions. Quaternary structure: This level of protein structure refers to the arrangement of multiple protein subunits (if present) and their interactions to form a functional protein complex.
Which level of protein structure may be stabilized by covalent bonds?
Primary, tertiary and quaternary levels of protein structure.
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.
Which level of protein structure is most related to specificity?
The tertiary structure of a protein is most related to specificity. This level of structure is where the unique three-dimensional arrangement of amino acids within a protein allows it to interact specifically with other molecules, such as enzymes with their substrates.
