Quick Bites. In a tourniquet test for dengue, the blood capillaries are examined for their ability to withstand increased pressure. This gives a good indication for assessing the blood vessels and whether it will lead to Dengue Shock Syndrome (DSS) or Dengue Hemorrhagic Fever (DHF).
sugÂ·ar. n. 1. A sweet crystalline or powdered substance, white when pure, consisting of sucrose obtained mainly from sugarcane and sugar beets and used in many foods, drinks, and medicines to improve their taste. Also called table sugar.
Also known as sucrose, sugar is made up of 22 hydrogen atoms, 11 oxygen atoms and 12 carbon atoms in each molecule. Sucrose is made up of two simple sugars, fructose and glucose. Sugar is a carbohydrate that has 45 atoms. Under a microscope, a molecule of sugar looks like a cube. When cooking, acid is added to the sugar to break the cube apart. The acid breaks the sucrose down into fructose and glucose. Sugar exists in most plants.
