Tay-Sach''s disease is due to the presence of an enzyme that is inverted in the catabolism of:
Correct answer: D. Lipids
- A. Proteins
- B. Ascorbic Acid
- C. Carbohydrates.
- D. Lipids
Explanation
Explanation:Tay Sach disease is a lipid storage disease. The enzyme absent is involved in catabolism of lipids. Proteins are broken down into their constituent amino acids by a different set of enzymes, and the presence of absence of these enzymes is not associated with Tay-Sachs disease. Ascorbic acid, also known as Vitamin C, is not catabolized by any known enzyme that is associated with Tay-Sachs disease. Carbohydrates are broken down into simpler sugars by different enzymes, and the presence or absence of these enzymes is not associated with Tay-Sachs disease.

About Lipids
Lipids include fats, oils, waxes, phospholipids and steroids, which are largely insoluble in water and soluble in organic solvents. Coverage includes glycerol and fatty acids, ester bond formation, saturated and unsaturated fats, triglyceride functions, and phospholipids in cell membranes.
