sugar is the generic name for sweet-tasting, soluble carbohydrates, many of which are used in food. simple sugars, also called monosaccharides, include glucose, fructose, and galactose. compound sugars, also called disaccharides or double sugars, are molecules composed of two monosaccharides joined by a glycosidic bond. common examples are sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two molecules of glucose). in the body, compound sugars are hydrolysed into simple sugars. table sugar, granulated sugar or regular sugar refers to sucrose, a disaccharide composed of glucose and fructose.
on the other hand, water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of earth's hydrosphere, and the fluids of most living organisms. it is vital for all known forms of life, even though it provides no calories or organic nutrients. its chemical formula is h2o, meaning that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. water is the name of the liquid state of h2o at standard ambient temperature and pressure. it forms precipitation in the form of rain and aerosols in the form of fog. clouds are formed from suspended droplets of water and ice, its solid state. when finely divided, crystalline ice may precipitate in the form of snow. the gaseous state of water is steam or water vapor. water moves continually through the water cycle of evaporation, transpiration (evapotranspiration), condensation, precipitation, and runoff, usually reaching the sea.
