How does heat denatured protein?
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.
Can a protein fold with all hydrophilic amino acids?
It depends on the protein; some are hydrophobic, some are hydrophilic, some are amphipathic.Different areas of proteins are different; their primary and secondary structure determine this.
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 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 is the tertiary structure for a protein?
'The Quaternary structure of a protein is the 4th level of folding for a protein. An example of this would be a red blood cell, which is a quaternary structure, it is made up of alpha helicies and also beta pleated in the tertiary structure. The Quaternary structure of a protein contains 4 tertiary structures in it.

What is a three dimensional protein that is formed by the interaction of R groups in the primary structure?
This is not in the primary structure, or even from the primary structure. This folding of proteins into the globular final shape by the bonding interaction of R groups is called the tertiary phase of protein synthesis. ( tertiary means three )

Is the structure of protein primary?
The primary structure of proteins is simply a peptide (chain of amino acids).
Do all proteins have quandary structure?
No. Proteins start out as a Primary structure, which is just the linear form and sequence of amino acids. The proteins then start forming alpha helices and/or Beta sheets depending on the properties of the amino acids. This is their Secondary structure The proteins then fold completely into tertiary structure. Here, we have a lot of hydrogen bonding and hydrophobic interactions within the protein between the helices and beta sheets. Many proteins are fully functional in their tertiary structure and don't have any reason for forming into a quaternary structure. In the quaternary structure, we usually see an interaction between 2 or more polypeptides or proteins. An example would be 2 proteins in their tertiary structure binding together to become a functional dimer. If 3 proteins were interacting it would form a trimer. Several proteins are functional only in a quaternary structure while several more proteins are just fine in their tertiary structure and therefore do not have a quaternary structure.
At which level of protein structure are interactions between the side chains of R groups and other groups the most important?
Interactions between the side chains of R groups and other groups are most important in determining tertiary structure of a protein. This level of protein structure involves the folding of the polypeptide chain into a specific three-dimensional shape, driven by interactions such as hydrogen bonding, hydrophobic interactions, ionic interactions, and disulfide bonds.
What does the shape of a protein resembles?
Proteins are "folded" molecules there is not one shape, each protein is different. ---------------------------------------------------------------------------------------------- A protein has a primary structure which folds into a secondary structure (alpha helix or B-sheet) and then has a tertiary structure (its 3D fold). Many proteins can complex together to create a quaternary structure. ---------------------------------------------------------------------------------- Depending on the type of protein and the environment that the protein is in determines its "shape". The hydrophobic effect plays a huge role in this. Membrane proteins are in a hydrophobic environment, and cytosolic proteins are in a hydrophilic environment. ------------------------------------------------------------------------------------------------ If you are referring to an amino acid which is a polypeptide monomer, then amino acids have a tetrahedral shape around the alpha carbon. ---------------------------------------------------------------------------------- also known as a messy group of coat hangers
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.
