What is the main function of gangliosides?
Signaling and cellular recognition accurately defines or describes the concept asked in this question. Within Lipids without annotations, precise definitions and terminology are essential for clear scientific communication. The other options (Energy storage, Membrane fluidity, and Fat digestion) either describe related but distinct concepts, use incorrect terminology, or confuse similar-sounding terms that have different scientific meanings. A thorough understanding of exact definitions helps distinguish between closely related biological concepts and is crucial for competitive examinations.

Which of the following is not a major function of cholesterol?
Direct energy source is the correct choice because it does not accurately describe or belong to the category addressed in this question. In the context of Lipids without annotations, the other options (Precursor of steroid hormones, Component of plasma membranes, and Precursor for bile acids) are all valid and well-established concepts. Direct energy source is either unrelated to the topic, describes a different biological process, or represents a common misconception. Questions framed as 'which is NOT' require students to identify the exception among otherwise correct statements, demanding comprehensive knowledge of the topic rather than recognition of a single fact.
