Summary Introduction

To examine: Whether the statement “Each strand in a β sheet is a helix with two amino acids per turn” is true or false.

Introduction:

Proteins consist of a chain of amino acids called polypeptide. There are 20 different amino acids in proteins which are coded by organisms’ DNA. Protein structure is considered to contain four structural level: primary, secondary, tertiary structure, and quaternary structures.

Expert Solution & Answer

Answer to Problem 1P

Correct answer: The statement is true.

Explanation of Solution

The β-sheet is a secondary structure of the protein. This is formed by hydrogen bonding between the N-H and C=O groups in the polypeptide backbone. It can be arranged in a helical pattern to form helix. The axial distance between two amino acids in beta sheet is 3.5 Å. There are two amino acids repeat unit which give β strand a 7 Å pitch.

Hence, the statement is true.

a. What percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent. b. What will happen to elimination of the drug in the previous question if the system is saturated? explain and show any math involved

If you wanted to reduce the difference between peak and trough levels that occur with repeated administration of a drug, how would you adjust the dose and dose interval without changing the plateau concentration (plateau is the average of peak and trough levels)? Select your answers for both dose and interval. Hint: It may be helpful to think about this problem using an example such as food. How would you eat if you wanted to maintain very steady hunger/satiety levels without changing your total caloric intake? Options: A. Dose; Increase dose B. Dose; Decrease dose C. Dose; Do not change dose D. Interval; Increase the interval between doses (give the drug less frequently) E. Interval; Decrease the interval between doses (give the drug more frequently) F. Interval; Do not change the interval
