Proteins are generally larger than phospholipids. A typical protein can consist of hundreds to thousands of amino acids, resulting in a molecular weight that can range from several thousand to over a million daltons. In contrast, phospholipids are smaller molecules composed of a glycerol backbone, two fatty acid tails, and a phosphate group, usually having a molecular weight of around 600 to 1,000 daltons. Thus, proteins are significantly larger and more complex than phospholipids.

What 2 molecules make up the cell membrane?

Phospholipids and proteins are the two main types of molecules that make up the cell membrane. Phospholipids form a lipid bilayer that serves as the basic structure of the membrane, while proteins are embedded within this lipid bilayer and help to carry out various functions such as transport, signaling, and support.
