1. Glycerol: A three-carbon alcohol molecule with three hydroxyl groups (-OH).
2. Fatty acids: Long chains of hydrocarbons with a carboxyl group (-COOH) at one end.
Dehydration Synthesis:
In this process, a water molecule is removed from the glycerol and fatty acids, allowing them to bond together. This bond is called an ester linkage.
Neutral Fats:
The resulting molecule is called a triglyceride (or neutral fat). It consists of one glycerol molecule linked to three fatty acid molecules.
Key Points:
* Different fatty acids: There are many different types of fatty acids, varying in length, saturation, and presence of double bonds. This diversity impacts the properties of the neutral fat.
* Storage of Energy: Neutral fats are the body's primary energy storage molecule, providing more energy per gram than carbohydrates.
* Insulation and Protection: They also serve as insulation and protection for organs and tissues.
