In the proteins
A molecule that is water-loving and part of the phospholipid bilayer is a phospholipid. Phospholipids have a hydrophilic (water-loving) head and hydrophobic (water-fearing) tail, making them ideal for forming the bilayer structure of cell membranes.
It depends on which lipid bilayer you're talking about. There is the phospholipid bilayer that surrounds eukaryotic cells, cholesterol phospholipid bilayers, protein lipid bilayers, phase transition lipid bilayer, lipid bilayer membrane...
The Phospholipid Bilayer is made up of phospholipids. These phospholipids have a hydrophillic head, and a hydrophobic tail. They are structured so that the hydrophillic head interacts with water, and the hydrophobic tails stays away from water, but mixes with fat. This makes the phospholipids form the phospholipid bilayer. The Phospholipid Bilayer has intrinsic proteins and extrinsic proteins attached, which may have glycoproteins attached to them. Glycolipids may also be attached to the hydrophillic heads of the phospholipid. Cholestrol is also part of the phospholipid bilayer, which adds strengh to the structure.
The cell membrane is a phospholipid bilayer, consisting of two layers of phospholipid molecules. Each phospholipid molecule has a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tails, creating a barrier that controls the movement of molecules in and out of the cell.

Osmosis moves water molecules across the phospholipid bilayer of a cell membrane. Protein channels help facilitate the movement of water and other molecules by providing a pathway through the membrane.
The head of a phospholipid molecule is hydrophilic, meaning it is attracted to water, and is found on the outside of the lipid bilayer. The two tails are hydrophobic, meaning they repel water, and are located on the inside of the lipid bilayer.
Phospholipids are the primary type of molecule that forms the cell membrane. They have hydrophilic (water-attracting) heads and hydrophobic (water-repelling) tails, allowing them to arrange in a bilayer to create the cell membrane.
The hydrophilic "head" region of the phospholipid is in contact with water in a lipid bilayer. This head region contains a phosphate group and glycerol and is attracted to water molecules due to its polar nature.
The framework of the cell membrane is formed by the lipid bilayer. The lipid bilayer is composed of two layers of fat cells organized in two sheets. This is what provides the barrier that makes the boundaries of the cell.
The phospholipid bilayer is located in eukaryotic cells as the main component of the cell membrane, which surrounds the cell and separates its internal environment from the external environment. It provides a semi-permeable barrier that controls the movement of substances into and out of the cell.
