The Four Major Biological Molecules
Major Biological molecules
There are many Biological molecules but this discussion will be about the 4 Major biological molecules and how they are used in a living system. This discussion will also include major subtypes of molecules. The four Major biological molecules are Carbohydrates, Lipids, Proteins, nucleic acids.
Carb is an abbreviation for carbohydrates. The body breaks down carbohydrates into simple sugars. Carbohydrates are easily used for energy by the body. The nervous system and brain need the glucose formed from breakdown of carbohydrates. If carbohydrates are not available, the body burns lipids/fats for energy.
Lipids is the scientific name for fats. Lipids act as chemical messengers in the body. Lipids are the last to be digested and used by the body. Lipids make up about 6% of a human's weight. Lipids are the reason a human can live without eating for several day, with the least water it would take to be alive. A lipid has more than 2 times the amount of energy than Carbs. Lipids have 6 categories: Triglycerides, Steroids, Phospholipids, Glycolipids, Lipoproteins, and waxes.
