The disaccharide sucrose (also sucrose, disaccharide) is a carbohydrate. It is found in almost all plants and is used to transport energy and carbon in the phloem of the vascular tissue. Sucrose is found in high concentrations primarily in sugar cane and sugar beet, from which the chemically identical products cane sugar and beet sugar are obtained. These are also known as household or granulated sugar.
Chemically, sucrose consists of one molecule each of the monosaccharides glucose (grape sugar) and fructose (fruit sugar). It is produced during photosynthesis in the leaves and is transported to other parts of the plant, including the berries. There it is broken down (hydrolysed) into the two monosaccharides by the enzyme invertase. The resulting mixture is known as invert sugar.

If I were to rate websites, you would deserve the highest rating. It is rare to come across websites that provide such a large amount of data and are still so intuitive to use. Respect for the lovingly researched and informatively prepared encyclopedia. Keep it up!
