Here's how it works:
* Glycerol: A three-carbon molecule with three hydroxyl (-OH) groups.
* Fatty acids: Long chains of hydrocarbons with a carboxyl (-COOH) group at one end.
During dehydration synthesis, the hydroxyl group of glycerol reacts with the carboxyl group of a fatty acid, releasing a water molecule (H₂O). This forms an ester linkage. This process repeats three times, with three fatty acid molecules attaching to the glycerol molecule, resulting in a triglyceride.
Key takeaways:
* Triglycerides are the primary form of stored energy in animals.
* They are also important components of cell membranes.
* Dehydration synthesis is a crucial process in the formation of many biological molecules, including triglycerides.
