Cut watermelon, both pre-cut chunks and slices you make yourself, must be stored in the refrigerator. Bacteria multiply quickly when you leave cut watermelon in the âdanger zone,â between 41 and 135 degrees Fahrenheit. You can leave the watermelon out for two hours and still safely eat it.
Lactose: The sugar found in milk. Lactose is a large sugar molecule that is made up of two smaller sugar molecules, glucose and galactose. In order for lactose to be absorbed from the intestine and into the body, it must first be split into glucose and galactose. The glucose and galactose are then absorbed by the cells lining the small intestine.
Lactose intolerance is a condition that results from a deficit of lactase (lactase deficiency), an enzyme produced by the cells lining the small intestine. Lactase is necessary to digest lactose, the natural sugar found in milk. Lactase breaks down lactose (milk sugar) into two simpler forms of sugar called glucose and galactose, which are then absorbed into the bloodstream.
