Concept explainers
(a)
Interpretation:
Primary structure has to be explained based on structure, type of bond and molecular interaction.
Concept introduction:
Primary structure is the sequence of amino acid connected by peptide bond in a polypeptide chain.
(b)
Interpretation:
Secondary structure has to be explained based on structure, type of bond and molecular interaction.
Concept introduction:
Secondary structure is the arrangement of polypeptide chain, in a regular pattern of
(c)
Interpretation:
Tertiary structure has to be explained based on structure, type of bond and molecular interaction.
Concept introduction:
Tertiary structure is the folding of a single protein into a specific three dimensional shape, held by noncovalent interaction between the side chains.
(d)
Interpretation:
Quaternary structure has to be explained based on structure, type of bond and molecular interaction.
Concept introduction:
Quaternary structure is forms when two or more proteins chains assembles n a larger three-dimensional structure held together by noncovalent interaction.

- The following figure is a diagram (cartoon or caricature) of the structure of a protein. What types of secondary structure are observed in the molecule? Is it a globular protein or a fibrous one?arrow_forwardIn the illustration below, the blue squiggly line represents a protein. Notice that the amino acid that is colored red and the amino acid that is colored black are very close to each other in space, but they are far from each other in the primary structure of this protein. How can you explain why two amino acids that are so far from each other in the primary structure of a protein can be so close together in the tertiary structure of the same protein?arrow_forwardWhat level of protein structure is determined by the following:(a) Peptide bonds between amino acids?(b) Hydrogen bonds between backbone carbonyl oxygen atoms and hydrogen atoms attached to backbone nitrogen atoms?(c) R group interactions that may involve Van der Waalsforces, ionic interactions, or hydrogen bonds?arrow_forward
- Why is the ionic bond between, say, the side chain of lysine and the side chain of glutamic acid stronger in the hydrophobic interior of a protein than in aqueous solvent (water)?arrow_forwardIdentify the following statements as descriptive of the secondary, tertiary, or quaternary structure of a protein. What types of interactions stabilize each type of structure?(a) The polypeptide chain has a number of bends and twists, resulting in a compact structure.(b) The polypeptide backbone forms a right-handed coil.(c) The four polypeptide chains are arranged in a spherical shape.arrow_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_forward
- While abnormal physiological conditions such as high urea concentration and very high/low pH can affect proteins, can they affect the primary structure (peptide bonds and such)?arrow_forwardIn regards to the protein structure, explain what is meant by “tertiary structure.” Whatare the main forces that stabilize tertiary structures in proteins? Provide examples.arrow_forwardDiscuss and identify the four levels of protein structure (primary, secondary, tertiary,and quaternary). Explain how the structure of a protein affects its properties and howdenaturation changes the structure.arrow_forward
- is Tertiary protein structure come from secondary structure?How are they related?(do we need to build up a secondary structure before make it become tertiary?)arrow_forwardHow do the following interactions help to stabilize the tertiary and quaternary structure of a protein? Give an example of a pair of amino acids that could give rise to each interaction.(a) Side-chain hydrogen bonding(b) Disulfide bondsarrow_forwardMost proteins can easily dissolve in water. Knowing that, where within the overall three-dimensional shape of a protein would you most likely find hydrophobic amino acids?arrow_forward
