Sweet, Sweet Carbs
Pure cane sugar is only one example of the sugars around youCarbohydrate is a fancy way of saying "sugar." Scientists came up with the name because the molecule have many carbon (C) atoms bonded to hydroxide (OH-) groups. Carbohydrates can be very small or very large molecules, but they are still considered sugars. Plants can create long chains of these molecules for food storage or structural reasons.
What's It Used For?
A carbohydrate is called an organic compound, because it is made up of a long chain of carbon atoms. Sugars provide living things with energy and act as substances used for structure. When sugars are broken down in the mitochondria, they can power cell machinery to create the energy-rich compound called ATP (adenosine triphosphate). Some examples of structural uses might be the shell of a crab (chitin) or the stem of a plant (cellulose). We'll talk about them in a little bit.
(answer from the internet but in my opinoin it would be because glucose is made up from hydrocarbons which contain Hydrogen , Oxygen and carbon see what makes more sense and write the answer )
