A chemical approach divides carbohydrates into three main groups, sugars (DP1–2), oligosaccharides (short-chain carbohydrates) (DP3–9) and polysaccharides (DP⩾10) . Sugars comprise (i) monosaccharides, (ii) disaccharides and (iii) polyols (sugar alcohols).
What are the classifications of carbohydrates?
Carbohydrates are divided into four types: monosaccharides, disaccharides, oligosaccharides, and polysaccharides .
What are the 3 classes of carbohydrates and an example of each?
| Aldoses Ketoses | (C6H12O6) Hexoses Glucose Fructose |

What are 3 carbohydrates examples?
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.
What are the 3 major classifications of carbohydrates?
- Sugars. They are also called simple carbohydrates because they are in the most basic form. ...
- Starches. They are complex carbohydrates, which are made of lots of simple sugars strung together. ...
- Fiber. It is also a complex carbohydrate.
What is carbohydrates and examples?
Beans and legumes , such as black beans, chickpeas, lentils and kidney beans. Fruits, such as apples, berries and melons. Whole-grain products, such as brown rice, oatmeal and whole-wheat bread and pasta. Vegetables, such as corn, lima beans, peas and potatoes.
What are the simplest carbohydrates?
Monosaccharides are the simplest carbohydrates. They typically contain three to six carbon atoms and cannot be hydrolyzed into smaller molecules. Examples include glucose and fructose.
What best describes the structure of carbohydrates?
Which of the following best describes the structures of carbohydrates? They occur as monomers, chains of monomers, and branched structures . The carbohydrates have different properties because they have different arrangements of carbon, hydrogen, and oxygen atoms.
What are characteristics of carbohydrates?
Carbs are composed of the elements carbon, hydrogen and oxygen , with generally twice the hydrogen as carbon and oxygen (this is the main characteristic of carbohydrates), according to Oregon State University. In its simplest form, a carbohydrate is a chain of sugar molecules called monosaccharides.
What are the basic structures of carbohydrates?
Carbohydrates are “hydrates of carbon” and have the generic structure of C(n)H(2n)O(n) . A single sugar unit is a monosaccharide. These can consist of 3-carbon moieties (triose), 4-carbon units (tetrose), 5-carbon moieties (pentose), and 6-carbon moieties (hexose).
What is the main difference between simple and complex carbohydrates?
Simple carbohydrates are in foods such as table sugar and syrups. Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates . The body converts these sugar molecules into glucose, which it uses for energy.
Which are the two main classes of complex carbohydrates?
What are the two major types of complex carbohydrates? Glycoproteins and proteoglycans .
What are the 6 simple sugars?
| Monosaccharides Disaccharides | Glucose Sucrose (glucose + fructose) | Fructose Lactose (glucose + galactose) | Galactose Maltose (glucose + glucose) |

What are Class 4 carbohydrates?
Carbohydrate is the sugar, starch and fibre found in regular food items like fruits, grains and dairy products. It is one of the three micronutrients via which a human body obtains energy. The properties of carbohydrates biology include carbon, hydrogen and oxygen atoms at its chemical level.
What are 10 examples of carbohydrates?
- Breads, grains, and pasta.
- Nuts and Legumes.
- Starchy Vegetables.
- Milk and yogurts.
- Fruits.
- Snack Foods.
- Sauces and condiments.
