Carbohydrates are macronutrients that are composed of carbon, hydrogen, and oxygen atoms. They are one of the main sources of energy for the human body and are found in various forms in foods such as grains, fruits, vegetables, and legumes.
Monosaccharides are the simplest form of carbohydrates, consisting of a single sugar molecule. Some common examples of monosaccharides include glucose, fructose, and galactose. They are usually sweet in taste and are easily absorbed into the bloodstream.
Disaccharides are carbohydrates composed of two linked monosaccharide molecules. Examples of disaccharides include sucrose (table sugar), lactose (milk sugar), and maltose (found in grains). Disaccharides are broken down into monosaccharides during digestion so that they can be absorbed and used for energy.
Polysaccharides are complex carbohydrates consisting of many monosaccharide units joined together by glycosidic bonds. They can be categorized into two types: storage polysaccharides and structural polysaccharides. Storage polysaccharides, such as starch in plants and glycogen in animals, serve as a form of energy storage. Structural polysaccharides, like cellulose in plants and chitin in fungi and animal exoskeletons, provide structural support. Unlike monosaccharides and disaccharides, polysaccharides are not sweet-tasting and take longer to be broken down and absorbed by the body.
