Structure of the protein has 4 parts
A) primary structure :The first part of protein structure is primary structure is simply the sequence of amino acids in a polypeptide chain.
B) secondary structure Is the folded structures that form within a polypeptide due to interactions between atoms of the backbone.
C)tertiary structure Is the overall three-dimensional structure of a polypeptide The tertiary structure is primarily due to interactions between the R groups of the amino acids that make up the protein.
D) quaternary structure some proteins are made up of multiple polypeptide chains, also known as subunits. When these subunits come together, they give the protein its quaternary structure
Option b is correct

Which of the following is true about proteins? a. Peptides linkages are made between the side chain and the carboxyl group. b. Hydrogen bonding between the NH and CEO of the backbone results in only alpha helices! c. Electrostatic interactions between the NH and C=O of the backbone results in only beta sheets. d. Quaternary structures of proteins involve multiple peptide chains interacting together.

Review| Constants| Periodic Table Protein structure is conceptually divided into four levels, from most basic to higher order Primary structure describes the order of amino acids in the peptide chain. Secondary structure describes the basic three-dimensional structures, a-helices and B sheets. Tertiary structure describes how the secondary structures come together to form an individual globular protein.

QUESTION 2 Select the CORRECT statements (chose all that are correct). Secondary protein structures are held together by disulphide bridges/bonds. Alpha helices and beta sheets are common secondary protein structures. Tertiary protein structures are held together by covalent bonds only. Secondary protein structures are held together by hydrogen bonds only. All proteins have a quaternary protein structure. Amino acids linked with a peptide bond make up the primary protein structure.

1. Amino acids are considered to be either hydrophobic or hydrophilic as described by the relative polarity of their side chain. Consider a folded protein in an aqueous environment; where would the hydrophobic amino acids likely be found? -Tucked away in the middle of the folded protein -Randomly distributed throughout the protein -Exposed on the exterior surface of the folded protein 2. All proteins exhibit a primary, secondary, and tertiary structure, but not all proteins exhibit a quaternary structure. Describe...

QUESTION 1 To study how proteins fold, scientists must be able to purify the protein of interest, use solvents like urea to denature the folded protein, and observe the process of refolding at successive time points. What is the effect of the solvents used in the denaturation process? a. The solvents break all noncovalent interactions. b. The solvents break all covalent interactions. c. The solvents create a new folded conformation. d. The solvents break some of the noncovalent interactions, resulting...

Question 10 (4 points) Although all protein structures are unique, there are common structural building blocks that are referred to as regular secondary structures, Some proteins have alpha-helices, some have beta-sheets, and still others have a combination of both. What makes it possible for proteins to have these common structural elements? 12 15 a) the hydrophobic-core interactions. b) hydrogen bonds that form along (alpha helices) or between (beta sheets) polypeptide backbones. c) side-chain interactions d) specific amino acid sequences. 7...

True or false? True False Phenylalanine's side chain is more polar than tryptophan's or tyrosine's side chains. True False Almost all peptide bonds in proteins are in the trans configuration. True False In folded globular proteins, the side chains of hydrophobic amino acids are mostly buried in the interior of the protein. True False The peptides I-A-G-Y-L-S and S-L-Y-G-A-I are different molecules with different properties. True False Poly lysine will tend to form an alpha helix in solution at pH 6.8. True False Amyloidoses such as...
