What type of interaction would you expect between phenylalanine and leucine in a tertiary structure?
hydrophobic
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 the difference between the amino acid content of gelatin and casein?
Gelatin is the product of the denaturation of collagen. Collagen is a triple helical molecule that is composed nearly by one third of its residues with Glycine and a 15 to 30% of its residues by Proline and 4-hydroxyproline. When the collagen loses it's triple helix configuration, occurs gelatinization.On the other hand, Casein, the most abundant protein in milk, contains a fairly high number of Proline residues, which do not interact each other, there are no disulfide bridges in it's structure, and therefore it has relatively little tertiary structure.According to above, the main difference between gelatin (denatured collagen) and casein are the 4-hydroxyproline residues, that allow to collagen to form its characteristic triple helix.
What are the structure levels of proteins?
1st level, 2nd level, Tertiary, and Quaternary. The first level is just the different protein groups forming peptide bonds to create a polypeptide The second level consists of hydrogen bonds between the H and the O molecules in the proteins forming pleated and helical shapes The Tertiary structure is the interactions of different R groups binding to each other (many different types of bonds happen between the R groups) The Quaternary structure is many polypeptides interacting with each other
How does high temperature affect tertiary structure of a protein?
High temperature denatures most proteins. This means that the 3D structure (tertiary and quaternary structure) changes in a way that the molecule loses its biological function. Denaturation by heat is irreversible.
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 the difference between tertiary and quatarnary?
The Tertiary Period and Quaternary Period are divisions of geologic time. The Tertiary Period occurred first, from 65.5 to 2.6 million years ago, and covers the time period from the extinction of the dinosaurs to the beginning of the Ice Ages. The Quaternary Period occurred from 2,588,000 years ago until today, beginning when glaciation started.
What is the function of beta mercaptoethanol?
It is used to reduce all disulfide bonds between cysteine residues in order to disrupt the tertiary and quaternary structures of proteins.
Differentiate between secondary and tertiary structure by describing the parts of the polypeptide chain that participates in the bonds that hold together each level of structure?
Secondary tertiary is the R groups interactions that are ionic. The polypeptide chain also has disulfide bond, and hydrophobic interactions.
What type of interaction would you expect between phenylalanine and leucine in a tertiary structure?
hydrophobic
Hydrogen bonds between different parts of the polypeptide chain result in which level of protein structure?
Tertiary structure
Why is secondary called secondary?
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 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.
How is tertiary protein structure dependent on primary protein structure?
The relationship between the primary and tertiary structure of a protein is the both have a sequence of amino acids in a polypeptide chain.orThe sequence of amino acids in a primary structure determines its three-dimensional shape ( secondary and tertiary structure)
