5 Questions
Explain the structure and importance of Phosphatidyl glycerol (Phosphatidic acid).
Structure: Glycerol, Saturated F.A at C1 (α), Unsaturated F.A at C2 (β), Phosphoric acid at C3. Importance: It is the simplest, parent, precursor of all glycerophospholipids.
What is the structure of Di-pamityl lecithin (lung surfactant) and its significance?
Structure: lecithin + 2 molecules of palmitic acid. Significance: It is produced by epithelial cells and decreases surface tension of the aqueous layer of lung preventing the.
List the types of phospholipids and provide a brief explanation of Glycero-phospholipids.
Types of phospholipids: a) Glycerophospholipids, b) Sphingophospholipids. Glycero-phospholipids contain glycerol as a back bone and include various components such as Phosphatidyl glycerol, Phosphatidyl choline, Phosphatidyl ethanolamine, Phosphatidyl serine, Phosphatidyl inositol, Cardiolipin, and PAF (plateltes activating factor) which is involved in blood clotting.
What is the structure of Phosphatidyl choline (Lecithin) and its importance?
Structure: Phosphatidic acid + choline. Importance: It serves as a lung surfactant.
What is the significance of PAF (plateltes activating factor) and its role in physiological processes?
Significance: PAF is involved in blood clotting and is important for physiological processes.
