1. Lipids (non-polar) They prevent the cell from dissolving in its environment Ex: (fatty acid tails) maintains the structure of the cell and hence, us! a. Phospholipids: A fatty acid tail (non-polar) attached to one phosphate group (polar) - Heads: Phosphates (polar) - Tails: Lipids (non-polar) 2. Cholesterol Function- Prevents fatty acid tails from sticking together Location- between fatty acid tails 3. Proteins Aid in the transport of molecules in and out of cell; function as receptors allow intercellular communication and recognition of cell type; facilitate chemical reactions (enzymes) Location- traverse the entire membrane or one half. Ex: transport protein a. Enzymes: type of protein that facilitates chemical activity in the cell b. Speed up chemical reactions; breaks down molecules; synthesis of new molecules. 4. Carbohydrate Act as receptors to other glucose molecules and helps guide hormones to the proper cells. Ex: glycoprotein (attached to a protein) 5. Cell Membrane Made up of- primarily proteins and phospholipids Selective Permeabilityallows only some substances to pass through.
