The molecules that are present in a cell membrane include:

1. Lipids (fats): The most abundant lipids in most membranes are phospholipids. These are important for the basic functionality and structure of the membrane.

2. Carbohydrates: These are present on the exterior surface of the cell membrane. They are bound either to proteins (forming glycoproteins) or to lipids (forming glycolipids) and are involved in cell recognition and interaction.

3. Proteins: These are embedded within the cell membrane and are responsible for most of the complex functions of the cell membrane. They can function as enzymes, transporters, signal transducers, support for the membrane, etc.

Hydrocarbons are not typically found in cell membranes. They are nonpolar and hydrophobic, and thus do not interact well with the polar molecules that make up the majority of the cell and its membrane.
