Phospholipids are the main molecules in membranes that allow lipids and water to mix. They contain both hydrophobic (lipid-loving) and hydrophilic (water-loving) regions in their structure, enabling them to form the basic structure of cell membranes. The hydrophilic head interacts with water, while the hydrophobic tail interacts with lipid molecules.
fatty acids (APEX)
A cell membrane is basically a double layer of lipids (fat molecules) with a bunch of proteins in it. Each fat molecule has two molecular "tails" that don't mix with water (just like oil doesn't) and one extremity that does. Because of this characteristic the part that does mix with water is facing outward (cells are immersed in water environments) or inward (cells are mostly water on the inside) and the double "tails" are sandwiched on the inside, there they don't come into contact with water, only with eachother and other molecules that don't mix well with water. There are basically two types of protein that are found in the membrane: - some that cross all the way through, called 'transmembrane'. These are able to do this because they, like the double layer of positionally opposite fat molecules, have one part that doesn't mix with water and two parts that do. Membrane pores for instance would be of this type. - Some that are on the periphery of the double layer, either on the outer part or inner part, called 'peripheral proteins'. These mix with water and consequently they also mix well enough with molecules that mix with water.

Lipids are hydrophobic molecules, meaning they do not mix well with water. This is because lipids have nonpolar regions that repel water molecules. This relationship is important in biological systems, as it allows lipids to form cell membranes and other structures that help regulate the flow of substances in and out of cells.

A false statement about lipids would be that they are water-soluble molecules. In reality, lipids are hydrophobic, meaning they do not mix well with water. They include fats, oils, waxes, and sterols, and are essential components of cell membranes and energy storage in living organisms.
16/23 parts mix.
frozen mix is the solute The water/ice is the solvent.
Lipids are a diverse group of molecules that include fats, oils, waxes, phospholipids, and steroids. They serve as energy storage, provide structural support to cell membranes, and act as signaling molecules in the body. Lipids are hydrophobic, meaning they do not mix well with water.
