Question

Which amino acid will mostly likely be present in the outer side of trans membrane domain of an Integral protein facing the hydrocarbon tail of phospholipids :
a. a charged amino acid like lysine
b. a polar amino acid like serine
c. a special amino acid like proline
d. a hydrophobic amino acid like valine

Accepted Answer

***D*** ∻Key Concept∻ ⚹Hydrophobic amino acids and membrane integration⚹ ∻Explanation∻ ⚹Hydrophobic amino acids like valine are likely to be found in the transmembrane domains of integral proteins facing the hydrocarbon tails of phospholipids due to their nonpolar nature, which allows them to interact favorably with the lipid bilayer's hydrophobic environment.⚹◊What role does the presence of hydrophobic amino acids like valine play in the structure and function of integral membrane proteins?⍭ Generate me a similar question◊
