The Structure and Function of the Cell Membrane

            The mosaic fluids that are in the cell membrane include lipids, proteins and carbohydrates. First I'll describe lipids which are sparingly to insoluble tin water. Lipids are also hydrophobic. Lipids are very important and they serve many functions in organisms. Fats, steroids, and phospholipids are also very important to the functioning of membranes in cells.
             Fatty acids are attached to the alcohol glycerol and this is how fats are synthesized. Fatty acids can be one of the two: saturated and unsaturated. These "double bonds" introduce kinks in the carbon chain which has important consequences on the fluid nature of lipid membranes. Unsaturated fat has at least one unsaturated fatty acid while saturated fat has none. Usually any kinds of fat contains a storage for energy. Layers of fat also protect animals by cushioning them,  and adding layers of fat under the skin of animals to provide insulation.
              Phospholipids contain only two fatty acid tails attached to a glycerol head. When phospholipids are in an aqueous solution they will self assemble into micelles or bilayers. These two structures exclude water molecules for the hydrophobic tails while keeping the hydrophilic head in contact with the aqueous solution.
             Steroids are many lipids bunched together to make a molecule with four fused carbon rings. Steroids include many hormones and cholesterol.

Self evaluation-

             When I was reading the article "The Structure and Function of the Cell Membrane" I learned a lot of valuable useful information I can use to study more about the structure. I learned that I learn better when I'm reading an article in-front of me. I thought it was interesting that there are two types of fatty acids: unsaturated and saturated. Fatty acids usually store energy in the body. Learning about the cell membranes is interesting and very good to learn about.
