Lipids are one of the four major macromolecules but they are NOT true polymers because their individual lipid molecules are NOT connected by covalent bonds. Instead one lipid molecule is connected to another lipid molecule by hydrophobic interactions.

Lipids are held together by nonpolar covalent bonds, which are formed between the carbon and hydrogen atoms in their structure. These bonds are strong and stable, providing the structural integrity to lipids. Additionally, lipid molecules can also interact through weak intermolecular forces like van der Waals forces and hydrophobic interactions.
protein molecules that are embedded in the lipid bilayer. These proteins help stabilize the structure of the membrane and regulate the movement of molecules in and out of the cell. Additionally, interactions between the lipids themselves, such as hydrophobic interactions and van der Waals forces, also contribute to holding the lipids in place within the membrane.

Lipids are insoluble, so they will form a layer on top of the water, much like when oil from a spillage will float above the water's surface, as it is less dense than the water. They will not dissolve.
Unsaturation in the hydrocarbon tails of membrane lipids introduces kinks in the structure, which prevents the lipids from packing tightly together. This increases the fluidity of the membrane, allowing it to remain flexible and dynamic at different temperatures.
That are the lipids. They have fatty acids and glucerols
