D
Triglycerides
Verified step by step guidance
1
Understand the question: The problem asks about the class of lipids from which sex hormones and adrenal hormones are derived. This requires knowledge of lipid classification and their biological roles.
Recall the structure and function of steroids: Steroids are a class of lipids characterized by a four-ring structure (cyclopentanoperhydrophenanthrene). They serve as precursors for sex hormones (e.g., estrogen, testosterone) and adrenal hormones (e.g., cortisol, aldosterone).
Compare steroids with other lipid classes: Phospholipids are major components of cell membranes, glycolipids are involved in cell recognition, and triglycerides are storage forms of energy. None of these classes are directly involved in hormone synthesis like steroids.
Relate the biological role of steroids to the synthesis of hormones: Steroids are synthesized from cholesterol, which is a precursor for both sex hormones and adrenal hormones. This highlights their unique role in endocrine function.
Conclude that sex hormones and adrenal hormones are derived from steroids: Based on their structure and function, steroids are the correct class of lipids associated with these hormones.
