Describe how nonpolar R groups participate in the organization of protein secondary structures in a folded cytoplasmic protein.
Homework Answers
R group begin to cause an effect in the protein when R groups interact or R groups and the mainchain atoms interact to create the overall fold of a protein (ie. Secondary structure). At that secondary level, you can get ionic interactions between two oppositely charged amino acid R groups.
R groups with like charges repel one another, while those with opposite charges can form an ionic bond. Similarly, polar R groups can form hydrogen bonds and other dipole-dipole interactions.

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.

Differentiate between motifs and domains by matching each phrase to the appropriate term.

An αlpha- helix is formed by hydrogen bonds between: a. nonpolar and polar R groups. b. positively charged and negatively charged R groups. c. the carbonyl oxygen and the amide nitrogen of neighboring amino acids. d. the carbonyl oxygen and the amide nitrogen of every fourth amino acid.
Since the secondary structure of a protein results from hydrogen bonding between components shared by all amino acids
Distinguish between the different levels of protein structure, including primary, secondary, tertiary, and quaternary Question Is the following statement true? If not, explain why not: Since the secondary structure of a protein results from hydrogen bonding between components shared by all amino acids (a hydrogen on an amide N on one amino acid interacts with an oxygen on the carbonyl of another amino acid), the secondary structure does not depend on the specific amino acid groups (the R-groups) in the amino acid chain.

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...
