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.
Disaccharides are the most common form of sugar found in nature, rather than monossacharides. They are the carbohydrates that we actually eat, and are made of two monossacharides bonded together; in order to produce energy, we must first break dissacharides down into monossacharides.
