What are Disaccharides? Disaccharides are carbohydrates which contain two covalently linked monosaccharide units. Sucrose, Maltose, Lactose, Trehalose and Cellobiose are naturally occurring disaccharides. The individual monosaccharide units in a disaccharide are called ‘residues’. All disaccharides are soluble in water Glycosidic bonds links monosaccharide units The monosaccharide units in disaccharides (and […]
Monosaccharides are Simplest Sugars Monosaccharides are the simplest carbohydrates. They are polyhydroxy aldehydes or ketones with a carbon backbone. The carbon backbone in monosaccharides usually consists of 3 – 6 carbon atoms. The simplest monosaccharides are glyceraldehyde and dihydroxyacetone (with 3 carbons). The most abundant monosaccharide in nature is a […]
Carbohydrates are polyhydroxy aldehydes or ketones Carbohydrates are the most abundant bio-macro-molecules on the earth. They are commonly known as sugars because most of them have a sweet taste. Chemically all carbohydrates are polyhydroxy (contain many hydroxyl, – OH, groups) aldehydes or ketones. All carbohydrates are hydrates of carbon and […]
Collagen vs Keratin Collagen and Keratin are the main structural proteins. They are two main families of fibrous proteins and are abundantly present in the extracellular matrix and various connective tissues in animals. Collagen: A linear structural fibrous protein abundantly found in the connective tissue and extracellular space of the […]
