I'm pretty sure it's quaternary

What is the difference between interchain and intrachain hydrogen bonds in the secondary structure of proteins?
IntrAchain H-bonds stabalize bonds between the same polypeptide chain (alpha-helices). IntErchain- H-bonds stablized between different polypeptide chain. (beta- structures)
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 r group in the tertiary structure OS protein ch2c000 and ch2ch2ch2ch2nh3?
Well, there's --CH2COO- and --CH2CH2CH2CH2NH3+ which would mean that there's an electrostatic (ionic) interaction between the two R-Groups.
How can you distinguish between primary secondary tertiary and quaternary structures of proteins and can you give an example of each?
Primary structure of proteins refers to the exact sequence of the amino acids in the polypeptide chain. Secondary structure refers to the shape acquired by the backbone of the polypeptide chain when hydrogen bonds form between the carboxylic group of one amino acid and the amide group of another amino acid. there are two shapes in secondary structured proteins: Alpha Helix and Beta-pleated sheet tertiary structure refers to the shape taken up by the polypeptide chain as a result of bonds formed between the R-groups of the amino acids. three types of bonding may exist: Hydrgen bond, ionic bond and /or disulphide bonds.
Is the bonding in phospholipids covalent or ionic?
interaction with water, dipole dipole interaction, within the phospholipid itself covalent
What maintains the primary polypeptide structure?
Peptide bonds between the individual amino acids.
Hydrogen bonds between different parts of the polypeptide chain result in which level of protein structure?
Tertiary structure
The structure of a protein that involves the interaction between two distinct polypeptide chains is?
Protein is made up of amino acids and these acids have peptide bonds between them. As there are different numbers of amino acids in each type of protein, they have different number peptide bonds. Mostly all proteins are polypeptides.
Is a quaternary structure a polypeptide sequence of amino acids?
No, the polypeptide sequence of amino acids is the primary structure of a protein. The quaternary structure of the protein is the non-covalent interactions (hydrophobic binding, van der wals forces etc..) between subunits/domains of a protein.
What is a difference in the structure of proteins and polysaccharides?
Polysaccharides are essentially many carbon sugar "rings" linked together. They are carbohydrates, and our bodies break them down into monosaccharides (single "rings") to gain energy. To provide energy is their main function. In contrast, a peptide bond is formed between two amino acids via dehydration synthesis. Amino acids are the monomers for proteins within the body, who function in part to catalyze reactions and carry out other directions of DNA. Many peptide bonded amino acids = a polypeptide. The most basic difference would be that polypeptides are proteins, where as polysaccharides are carbohydrates.
What type of interaction stabilizes the secondary structure of a protein causing it to form an alpha-helix?
In an α-helix, the polypeptide backbone forms a repeating helical structure that is stabilized by hydrogen bonds between a carbonyl oxygen and an amine hydrogen. These hydrogen bonds occur at regular intervals of one hydrogen bond every fourth amino acid and cause the polypeptide backbone to form a helix.
What is the difference between interchain and intrachain hydrogen bonds in the secondary structure of proteins?
IntrAchain H-bonds stabalize bonds between the same polypeptide chain (alpha-helices). IntErchain- H-bonds stablized between different polypeptide chain. (beta- structures)
What type of interaction would you expect between phenylalanine and leucine in a tertiary structure?
hydrophobic
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.
The personality theory based on the interaction between an individual's behaviors thoughts and social inputs is?
reciprocal determinism.
Performance is a function of motivation, ability, and?
Performance is a function of the interaction between an individual's motivation, ability, and environment.
Which of the following is the best definition of the term phenotype?
Genotype is the alleles (different forms of a gene) which an individual has with respect to a particular characteristic. The Phenotype is how these genes are expressed in an individual.
