Saccharides, or carbohydrates, are vital biomolecules that control energy in cells, provide structural integrity, and play a role in the immune system, development, and fertilization. They are the most abundant organic matter on the planet and form the backbone of energy storage and metabolic processes. Monosaccharides, such as glucose, galactose, and fructose, are the basic compounds that make up polysaccharides, which are carbohydrate structures made up of chemically bonded repeating units. Polysaccharides are macromolecules that exhibit various properties, such as repositioning of atoms and possible insolubility in water.
Saccharides are one of the most important biomolecules in the world. Also known as carbohydrates, they are responsible for various roles in all living things, most notably in controlling energy in cells and providing structural integrity. Additionally, saccharides play a role in the immune system, development, and fertilization.
These molecules are the most abundant organic matter on the planet. They provide the basic backbone of energy storage, fuel cellular function and stabilize metabolic processes. Furthermore, saccharides form the structural framework of ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) with the basic sugars ribose and deoxyribose. Bacterial and plant cell walls are made up of the biomolecule, resulting in its overwhelming abundance. Finally, these carbohydrates play the key role in controlling the interactions of the cells themselves and the collections of cells. This is caused by saccharide binding with proteins and lipids.
Saccharides are composed of two basic compounds: aldehydes and ketones, both of which contain a carbonyl group composed of double bonded carbon and oxygen atoms. Aldehydes have the addition of a hydrogen atom, while ketones bond with two more carbon atoms. However, there are additional forms of saccharides that exhibit covalent bonds where electrons are shared by oxygen and hydrogen. These are known as hydroxyl groups.
When a compound for this biomolecule is harvested, it is known as a monosaccharide. The main examples of these are glucose, galactose and fructose. Glucose is also known as blood sugar and is the main source of energy for a cell. Galactose and fructose are also the main sugars. Galactose is most readily found in milk and dairy products, while fructose is found in most vegetables and fruits.
Monosaccharides come together into related groups known as polysaccharides. Polysaccharides are essentially carbohydrate structures made up of chemically bonded repeating units. This form of linkage is known as cosidic linkage. Usually, polysaccharides form in linear compounds; however, various ramifications can occur, changing the shape. Polysaccharides are known as macromolecules and exhibit a number of different properties such as repositioning of atoms and possible insolubility in water. An example of repositioning is in the form of DNA. DNA is simply RNA with a modified version of ribose called deoxyribose.
