Study Notes
Fats and Oils
- Fats and oils are lipids, which are organic compounds insoluble in water but soluble in organic solvents.
- Fats typically exist as solid at room temperature, while oils remain liquid.
Difference between Fat and Oil
- Fats are usually saturated or contain high levels of saturated fatty acids, leading to a solid state at room temperature.
- Oils are primarily unsaturated fats, which have one or more double bonds, keeping them liquid at room temperature.
Waxes
- Waxes are long-chain fatty acids esterified with long-chain alcohols, resulting in a solid form.
- They serve as protective coatings in various organisms.
Waxes in Nature
- Found on plant surfaces, providing a waterproof barrier that reduces water loss.
- Present in animal secretions, such as beeswax produced by honeybees for constructing honeycombs.
Sebum
- Sebum is an oily substance produced by sebaceous glands in the skin.
- Functions to lubricate and waterproof the skin and hair, offering protection against environmental damage and preventing moisture loss.
