Final answer:
Non-hydrolyzable lipids include cholesterol, bile salts, and sex hormones such as testosterone and estrogen. These lipids are unable to react with alkali to yield simpler components, making them an important component of cellular structures and functions.
Step-by-step explanation:
Non-Hydrolyzable Lipids
Examples of three non-hydrolyzable lipids include:
- Cholesterol: A type of steroid that is essential for maintaining the fluidity of cell membranes and is a precursor for steroid hormone synthesis.
- Bile salts: Steroids that aid in the digestion and absorption of dietary fats.
- Sex hormones: Such as testosterone and estrogen, which are steroids involved in regulating reproductive functions.
These lipids do not react with alkali to yield simpler components, thus they are classified as non-hydrolyzable. Lipids are hydrophobic or amphiphilic biochemical compounds that play various roles in cellular structure and function.
