AIIMS 2018 Zoology Biology MCQ Question
Which one of the following biomolecules is correctly characterized?
Lecithin-A phosphorylated glyceride found in cell membrane.
Palmiticacid-Anunsaturatedfattyacid with 18 carbon atoms.
Adenylic acid - Adenosine with a glucose phosphate molecule.
Alanine amino acid - Contains an amino group and an acidic group anywhere in the molecule.
Correct Answer
Detailed Explanation
The correct answer is A) Lecithin, which is indeed a phosphorylated glyceride commonly found in cell membranes. Lecithin is a phospholipid, consisting of glycerol, fatty acids, and a phosphate group, which allows it to play a crucial role in forming lipid bilayers that make up cell membranes. The other options incorrectly describe the structures or characteristics of the listed biomolecules.
