The complex relationships between the components in a system mean that a system is more than simply the sum of its parts. It has properties that are properties of the system a â¦ s a whole and cannot be attributed to any specific part of the system, known as 'emergent properties'.
A disaccharide (also called a double sugar or biose) is the sugar formed when two monosaccharides (simple sugars) are joined. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose, and maltose.
Sucrose, a common disaccharide, composed of one glucose molecule (left) and one fructose molecule (right). A disaccharide is a type of carbohydrate consisting of two monosaccharides (simple sugars) linked together by covalent bonds. Common nutritionally important disaccharides are sucrose, lactose, and maltose.
