Question

The chemical structure shown below is for sodium lauryl sulfate, a commonly used laboratory detergent. If you added this chemical to a culture of bacteria, they lyse. What would be a reasonable cause for this action on the cells? O-S-C Select all that apply: a. Many SDS molecules in solution will form a micelle due to the hydrophobic tails and the hydrophilic head. cross out b. The negatively charged oxygen atom would be exposed on the hydrophilic surface of the membrane cross out c. The amphipathic nature of this molecule can result in SDS inserting into the cell membrane. o d. The nonpolar portion of SDS can form van der Waals interactions with the hydrocarbonssou chains of the phospholipids. cross out

Explanation / Answer

SDS is an anionic detergent with sulphate hydrophilic head and carbon hydrophobic tail which helps to disintegrate into membrane of bacteria and lyse it. Small micelle are formed.

Here the correct answer is A.
