Select the true statements about protein secondary structure.
In an a-helix, the side chains are located on the outside of the helix.
The secondary level of protein structure refers to the spatial arrangements of short segments of the protein.
In a B-pleated sheet, the side chains are located between adjacent segments.
Peptide bonds stabilize secondary structure.
The x-helix is held together by hydrogen bonds between the amide N-H and C=O groups.
Incorrect
Oligosaccharides are usually attached to proteins on loops or turns that project from the protein surface. Explain why this is the case.
Proteins can be separated into 9 general classifications based on the role they play in a cell. List or briefly describe two of these functional classifications and provide an example of a protein that falls into each of those two categories.

- At what level of protein structure (primary, secondary, tertiary, or quaternary) will protein structure be initially altered? Heating a protein (due to fever), causing hydrogen bonds to break. Drastic changes in pH (like the above patients), causing some polar amino acids to turn into non-polar amino acidsarrow_forwardWhich of the following is the first step in folding a linear polypeptide into an ordered functional protein? O Secondary Primary Quaternary Tertiaryarrow_forwardThe protein will lose its conformation when denatured by some factors such as a big change in pH and this will lead to the loss of protein function even when the denaturing agent is removed. Select one: O True O Falsearrow_forward
- List two types of DNA mutations and state which one is more likely to have a severe effect on the resulting protein structure and function. Please explain in 5 sentences or less, thank you!arrow_forwardWhich statement best describes the protein structure shown below? This is an alpha helix. This is a tertiary structure that consists almost entirely of beta strands. This is a tertiary structure consisting of a roughly equal mixture of alpha helices and beta sheets. This is a beta sheet. This is a tertiary structure that consists almost entirely of alpha helices.arrow_forwardClassify each peptide chain as part of a parallel β sheet, part of an antiparallel β sheet, either type of β sheet, or not part of a β sheet. Parallel β sheet // Antiparallel β sheet // Either // Neitherarrow_forward
- There is a "primary driving force" behind protein folding (to form tertiary structure). This driving force can be used to explain below phenomenon except: water has a high density and a high boiling temperature non-polar amino acids go inside a protein long chain fatty acids form micelles oil spills go to the surface of water phospholipids form lipid bilayerarrow_forwardProtein structure is determined solely by a protein’s amino acid sequence. Should a genetically engineered protein in which the original order of all amino acids is reversed have the same structure as the original protein?arrow_forwardWhich level of protein folding is formed by interactions between amino acid side chains/R groups? primary secondary tertiary quaternaryarrow_forward
- Give an example of a protein containing primarily betapleated sheets. Is this a fibrous or globular protein?arrow_forwardMass spectrometry and X-ray diffraction are common biochemical techniques for characterizing proteins. Classify each statement based on whether it applies to mass spectrometry, X-ray diffraction, or both techniques. Mass spectrometry protein must be conformationally stable X-ray diffraction small amounts of protein are sufficient analysis requires information about the protein-coding gene or genes Answer Bank protein may be denatured requires a large amount of protein protein sample must be pure can detect a covalent modification to a protein Both techniquesarrow_forwardWhich of the following statements concerning complete protein hydrolysis is incorrect?
