sugar any of several water-soluble simple carbohydrates. The principal categories of sugars are monosaccharides, disaccharides, and polysaccharides. A monosaccharide is a single sugar, such as glucose, fructose, or galactose. A disaccharide is a double sugar, such as sucrose (table sugar) or lactose. A polysaccharide is a sugar made up of repeating units of glucose, such as cellulose, starch, and glycogen.

- Definition: Carbohydrate. Carbohydrate. The foods we eat contain nutrients that provide energy and other things the body needs. Most of the nutrients in food fall into three major groups: proteins, fats, and carbohydrates. The two main forms of carbohydrates are sugars (such as fructose, glucose, and lactose) and starches, which are found in foods such as starchy vegetables, grains, rice, breads, and cereals. The body breaks down (or converts) most carbohydrates into the sugar glucose, which is absorbed into the bloodstream.

Carbohydrates The carbohydrates are the compounds which provide energy to living cells. They are compounds of carbon, hydrogen and oxygen with a ratio of two hydrogens for every oxygen atom. The carbohydrates we use as foods have their origin in the photosynthesis of plants. They take the form of sugars, starches, and cellulose.The name carbohydrate means watered carbon or carbon with attached water molecules.Many carbohydrates have empirical formuli which would imply about equal numbers of carbon and water molecules.hey take the form of sugars, starches, and cellulose.

Carbohydrates What are carbohydrates? Carbohydrates are found in a wide array of both healthy and unhealthy foods—bread, beans, milk, popcorn, potatoes, cookies, spaghetti, soft drinks, corn, and cherry pie. They also come in a variety of forms. The most common and abundant forms are sugars, fibers, and starches. Foods high in carbohydrates are an important part of a healthy diet. Carbohydrates provide the body with glucose, which is converted to energy used to support bodily functions and physical activity.

Biomolecules (Introduction, Structure and Functions)- Carbohydrates Deoxyribose. Definition. noun. (1) An aldopentose (i.e. a monosaccharide with five carbon atoms) derived from the pentose sugar ribose by the replacement of a hydroxyl group with a hydrogen atom at the 2 position, leading to the net loss of an oxygen atom (hence the name).

- A carbohydrate is a biological molecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water); in other words, with the empirical formula Cm(H2O)n (where m could be different from n). This formula holds true for monosaccharides.

What are simple carbohydrates? Simple carbohydrates are those foods that contain carbohydrate that is quickly absorbed into the blood stream. Examples of foods that are simple carbohydrates are: candy, fruit juice, popsicles, sugar, honey, syrup, and regular soda. We often refer to simple carbohydrates to use when a person with diabetes is having a low blood sugar (hypoglycemia) and they need to bring their blood sugar up so they will consume foods that are simple carbohydrates.

- Medical Definition of Carbohydrates. Carbohydrates: Mainly sugars and starches, together constituting one of the three principal types of nutrients used as energy sources (calories) by the body. Carbohydrates can also be defined chemically as neutral compounds of carbon, hydrogen and oxygen. Carbohydrates come in simple forms such as sugars and in complex forms such as starches and fiber. The body breaks down most sugars and starches into glucose, a simple sugar that the body can use to feed its cells.
