Sugar. Polarised light micrograph of crystals of sucrose, also known as cane or beet sugar. It is a sweet, soluble, crystalline carbohydrate composed of linked glucopyranose and fructofuranose units. With dilute acids or invertase it is rapidly hydrolysed to give glucose and fructose. Sucrose sugar is easily digested and forms a major source of energy in humans. It is both a sweetener and a preservative, and is used in cooking and the food industry. A high consumption is associated with obesity and tooth decay.
