Animals and plants each require their own unique form of carbohydrates, fats and proteins to function. Humans have many chemical compounds present in the body, each classified as different macromolecules. Macromolecules include fats, carbohydrates, lipids, and nucleotides. Each of them performs its own unique function in the human body. Carbohydrates, or carbohydrates, are used to save the use of proteins in the body and use them as energy. Carbohydrates can be found in many foods, such as grains, fruits, and dairy products. “After carbohydrates are eaten, they are broken down into smaller units of sugar (including glucose, fructose, and galactose) in the stomach and small intestine (Iowa State University Extension and Outreach, n.d.).” In animals the role is to provide energy to muscles, fuel for the nervous system and enable fat metabolism. Carbohydrates are made up of many carbons and hydrogen bonded together by glycosidic bonds. Plants produce all types of carbohydrates, each of which performs different tasks. Cellulose is used to maintain the structure of plants, while pectins are used to aid the digestive system. Carbohydrates in their raw form are also used as amino acids, which are the building blocks of DNA. Carbohydrates are found in most fruits and grains. There are many types of carbohydrates; monosaccharides, disaccharides and polysaccharides each containing a certain number of sugars. Monosaccharides are classified based on the number of carbon atoms in its carbon skeleton. Some examples of monosaccharides are glucose, which is the basic sugar, fructose, and hydroxyl. Disaccharides (which are made up of monosaccharides) include sucrose, lactose, and maltose, which are all forms of sugars. Finally, polysaccharides are made up of both monosaccharides and disaccharides, these include...... middle of paper...... runaway muscles and body support. So, in conclusion, all forms of chemical compounds and macromolecules are essential in plants and animals. They all work together to maintain and support organisms. The lack of a single macromolecule leads to a decline in nutrients and prevents the body from functioning anymore. Works Cited Iowa State University Extension and Outreach. (n.d.).
