removed for you to read Have a little read: ... The cell membrane structure-Fluid mosaic model The cell membrane separates a watery cytoplasm from a watery external environment also known as ECF. The phospholipids are arranged in a double layer (lipid layer) with the hydrophilic heads facing outward (cytoplasm or ECF) and the hydrophilic tails turned in towards each other. The unsaturated fatty acids are not bonded to each other and form a fluid. Fluid Mosaic model. The term "fluid" is used because

Carbohydrates are: -quick source of energy -best for the brain and nerve tissues -there are simple and complex carbohydrate c. Fats- type of lipid and usually come from animals. Sources can be lard and butter. Fats are: -needed for vitamin absorption -creating cell lipids and steroids. -excess energy is stored as fat in the human body 2.

They are also required for normal eye‚ liver‚ kidney‚ and bone functions. Zellweger spectrum disorders result from dysfunctional lipid metabolism‚ including the over-accumulation of very long-chain fatty acids and phytanic acid‚ and defects of bile acids and plasmalogens which are specialized lipids found in cell

cells. The fats travel through the blood circulation to reach the liver where they are processed into ketone units. The ketone units then circulate back into the blood stream and are picked up by the muscle and other tissues to fuel your body’s metabolism. In a person without diabetes‚ ketone production is the body’s normal adaptation to starvation. Blood sugar levels never get too high‚ because the production is regulated by just the right balance of insulin‚ glucagon and other hormones.However

Macromolecules Biologically‚ there are four general types of macromolecules or biomolecules. They are carbohydrates‚ proteins‚ lipids and nucleic acids. Each of these plays an important role in maintaining life among living creatures and each is a piece of the elaborate puzzle of metabolism. Each has a different chemical composition and interacts with other molecules differently. Most of these biomolecules come from food sources and we are therefore already familiar with them. Without a
