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.
A disaccharide is two monosaccharides that are bonded together. The  water molecule is removed to form a disaccharide and this process  is called dehydration reaction.
