There are 3 groups of biochemical compounds that are very important for human life. Carbohydrates, lipids, and proteins are all essential organic compounds. Carbohydrates consist of monosaccharides, disaccharides, and polysaccharides, which all contain the same elements carbon, hydrogen, and oxygen. Carbohydrates give humans energy and nutrients that their body needs for daily life, and supports people's metabolism. Lipids are also consisted of carbon, hydrogen, and oxygen, but do not dissolve in water. Lipids also include steroids, waxes and fats. Lipids in some cases store more energy than carbohydrates. When it comes to fats, the consumption of unsaturated fats is preferred over saturated fats. Lipids keep us warm, wax creates a highly waterproof layer on surfaces, and steroids act as an alternative for quick gain of muscles. Vegetable oil and peanut oil are examples of lipids, and supply humans with needed fats for organs in the body. A third biochemical compound is protein.
Proteins are the most complex or at least one of the most complex organic compounds. They are composed of amino acids with the elements carbon, hydrogen, oxygen, and nitrogen. Proteins are very important because they make the skin, muscles, and essential chemicals for the human body. The most abundant protein is collagen, and there are more than 20 amino acids that exist in the human body.
