Answer: Proteins.

Explanation:

Proteins are organic molecules made of amino acids which are arranged in a linear chain and joined together through a peptide bond.

Membrane proteins are classified depending on their location:

Integral membrane proteins are part of a cell membrane and can either penetrate the membrane or associate with one side of a membrane. Peripheral membrane proteins are transiently associated with the cell membrane.

They perform many important functions:

Membrane receptor proteins: relay signals between the internal and external environments. Transport proteins: move molecules and ions across the membrane. Membrane enzymes: transform a molecule into another form Cell adhesion molecules: allow cells to identify each other.
