Inverted sugar syrup simple sugars is formed by a process of hydrolysis of sucrose. This mixture has the opposite direction of optical rotation as the original sugar, which is why it is called an "invert" sugar. Table sugar (sucrose) is converted to invert sugar by a chemical reaction called "hydrolysis". Heating a mixture or solution of table sugar and water breaks the chemical bond that links together the two simple-sugar components. The balanced chemical equation for the hydrolysis of sucrose into glucose and fructose is: Once a sucrose solution has had some of its sucrose turned into glucose and fructose the solution is
City proper offices. These questionnaires ask for the country-specific definition of urban areas, rural areas and city proper. In its glossary, the Yearbook defines "city proper" as "a locality defined according to legal/political boundaries and an administratively recognized urban status that is usually characterized by some form of local government".
