karbohydráty

Karbohydráty, commonly known as carbohydrates, are one of the three macronutrients found in food, alongside proteins and fats. They are essential organic compounds composed of carbon, hydrogen, and oxygen atoms, often with a hydrogen-to-oxygen atom ratio of 2:1, similar to water. Carbohydrates serve as the primary source of energy for the body's cells, particularly the brain and muscles.

Carbohydrates are broadly classified into simple and complex forms. Simple carbohydrates include monosaccharides like glucose and fructose, and disaccharides such as sucrose (table sugar) and lactose (milk sugar). These are quickly digested and absorbed, providing a rapid energy boost. Complex carbohydrates, also known as polysaccharides, are made up of long chains of sugar molecules. They include starches, found in grains, potatoes, and legumes, and fiber, which is indigestible by humans but crucial for digestive health. Complex carbohydrates are digested more slowly, offering a sustained release of energy.

The body breaks down digestible carbohydrates into glucose, which is then used for energy or stored as glycogen in the liver and muscles for later use. When carbohydrate intake exceeds the body's energy needs and storage capacity, it can be converted into fat. Adequate carbohydrate intake is vital for maintaining bodily functions, supporting physical activity, and preventing the breakdown of muscle tissue for energy. Dietary recommendations for carbohydrate intake vary, but they generally form a significant portion of a balanced diet.
