Lipids form through dehydration reaction releasing water
Question asked:
“Lipids, like the triglyceride above, are formed when glycerol and fatty acids go through a dehydration reaction. During the dehydration reaction, water is released. The bond formed during the reaction is a covalent bond. The formation of a covalent bond instead of a non-covalent bond is important because of the stability a covalent bond provides.”
Summary
Triglycerides are created by esterifying glycerol with three fatty acids through a dehydration (esterification) reaction that releases three water molecules. The resulting ester linkages are covalent bonds, and their covalent nature gives the molecule greater chemical stability compared to non‑covalent interactions.

- Triacylglycerol - an overview | ScienceDirect Topics
Triacylglycerols are formed by linking fatty acids with an ester linkage to three alcohol groups in glycerol. Triacylglycerols are the form in which fat energy is stored in adipose tissue. Triacylglycerols are sometimes referred to as triglycerides.
- Triglyceride - an overview | ScienceDirect Topics
Triglycerides are simple lipid which constituted one molecule of glycerol and three molecules of fatty acids. Triglyceride is the storage form of lipid , which is used for energy production. Triglycerides are found circulating in the blood where they are transported by very-low-density lipoprotein (VLDL).

A triglyceride is formed by attaching a fatty acid to the hydroxyl group (-OH) of each of these 3 carbons of glycerol through a process called esterification. This reaction is a dehydration synthesis reaction (water is removed) and the resulting bond is called an ester linkage (see figure below).

- Triglyceride - Wikipedia
A triglyceride (from tri- and glyceride; also TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids. Triglycerides are the main constituents of body fat in humans and other vertebrates as well as vegetable fat.

Fats and oils are called triglycerides (or triacylcylgerols) because they are esters composed of three fatty acid units joined to glycerol, a trihydroxy alcohol: Figure \(\PageIndex{1}\): Chemical reaction for the formation of a triglyceride.
