They help to stabilize the membrane structure as they form hydrogen bonds with water molecules in the fluid surrounding the cell.
They also act as receptors and help in cell identification, hormonal responses and neuron-transmission.
Glycoproteins can act as carrier proteins.

A cell's ability to distinguish one type of neighboring cell from another
To increase the Strength and Impermeability of the 'outer bi-lipid layer'. There are many other functions, as well! (Note: the inner bi-lipid layers are the endoplasmic reticulum.)
They are used as "id" tags
a cell's ability to distinguish one type of neighboring cell from another
Glycoproteins and glycolipids act as antennae, receiving chemical messages from other cells. They are also markers & identifiers that identify the cell to other cells.
The function of glycolipids and glycoproteins allow the cell to recognize each other. These form receptors on the outside of the cell to act as antigens.
The glyco (sugar) part of constituent lipids and proteins accumulate charges and are important in cellular "communication" with things in its environment.
Glycoproteins are commonly found at the surface of cells. They can be found in gastrointestinal mucus secretions, connective tissues, and blood plasma. Glycoproteins are also used as lubricants and protective agents. They play a role in cell-cell interactions. There are three types of glycoproteins: N-linked glycoproteins, O-linked glycoproteins, and nonenzymatic glycosylated glycoproteins.
Flippase is an enzyme that helps in the movement of lipids (such as phospholipids) between the two leaflets of a biological membrane. This process is important for maintaining proper membrane asymmetry.
The chorion is a membrane that surrounds the embryo and provides a protective barrier. It helps regulate gas exchange between the developing embryo and the surrounding environment, allowing for the exchange of oxygen and carbon dioxide. It also plays a role in facilitating nutrient transfer during embryonic development.
The nuclear membrane surrounds the nucleus and controls the movement of materials in and out of the nucleus. It helps protect the genetic material (DNA) inside the nucleus and provides structural support to the nucleus.
The outer boundary of an animal cell is called the cell membrane or plasma membrane. It acts as a protective barrier, regulating the movement of molecules in and out of the cell.
