What is a carbohydrate simple definition?

ANSWER. Carbohydrates are one of the three main classes of foods and a source of energy. Carbohydrates are mainly sugars and starches that the body breaks down into glucose (a simple sugar that the body can use to feed its cells).

What are sources of simple carbohydrates?

Simple carbohydrates are found naturally in foods such as fruits, milk, and milk products. They are also found in processed and refined sugars such as candy, table sugar, syrups, and soft drinks.

Why do we need carbohydrates?

What is the basic structure and function of a carbohydrate?

Monosaccharides. Carbohydrates are the most abundant biomolecule on Earth. Living organisms use carbohydrates as accessible energy to fuel cellular reactions and for structural support inside cell walls. Cells attach carbohydrate molecules to proteins and lipids, modifying structures to enhance functionality.

How are the carbohydrates classified?

Carbohydrates are divided into four types: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides consist of a simple sugar; that is, they have the chemical formula C6H12O6. Disaccharides are two simple sugars.

What are main 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.

What is the main source of energy of the human body?

Carbohydrates are the main energy source of the human diet. The metabolic disposal of dietary carbohydrates is direct oxidation in various tissues, glycogen synthesis (in liver and muscles), and hepatic de novo lipogenesis.

What is carbohydrate and example?

A carbohydrate is an organic compound such as sugars, starches, celluloses and gums, that occurs in living tissues and food. It is important for nutrition since it can be broken down into energy by people or animals.

Why are they called carbohydrates?
