Triacylglycerols are also called as:
Correct answer: C. Triglycerides or neutral lipids
- A. Phospholipids or sphingolipids
- B. Glycerolipids or fatty acids
- C. Triglycerides or neutral lipids
- D. Steroids or cholesterol
Explanation
The correct answer is Option C: Triacylglycerols are also called triglycerides or neutral lipids. These molecules consist of three fatty acid chains esterified to a glycerol backbone, making them a primary form of energy storage in animals. They are termed 'neutral' due to their nonpolar nature, which makes them hydrophobic and efficient at storing energy.Option A is incorrect because phospholipids and sphingolipids are different classes of lipids with distinct functions, primarily in cellular membranes.Option B is partially correct because it mentions glycerolipids, which include triacylglycerols, but also includes fatty acids, which are components of various lipids rather than a synonym for triacylglycerols. Option D is incorrect as it mentions steroids and cholesterol, which are structurally and functionally different from triacylglycerols.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
