Carbohydrase is the name of a set of enzymes that catalyze five types of reactions, turning carbohydrates into simple sugars, from the large family of glycosidases. [1] Carbohydrases are produced in the pancreas, salivary glands and small intestine, breaking down polysaccharides.
The site was updated in 2014 to replace the Standard Grade section with National 4 and National 5 sections. Gaelic versions of these were also made available. Until 2014, in the Higher section, Biology, English, Geography, Maths, Chemistry, History, Modern Studies, Physics and the Scotland-only subject Scottish Gaelic were available.
In 1904, two Germans, A. Kossel and H. D. Dakin, had shown that arginine could be hydrolysed by the enzyme arginase to form ornithine and urea in inorganic reaction. [28] Based on this reaction, Krebs and Henseleit postulated that in living cells, similar reaction could occur, and that ornithine and citrulline could be the intermediate reactions.
Organisation of enzyme structure and lysozyme example. Binding sites in blue, catalytic site in red and peptidoglycan substrate in black. (In biology and biochemistry, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.
Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...
In 1888, the Scottish Leaving Certificate was established in response to the terms of the Education Act of 1872. It was designed to have higher and lower levels assessed as individual subjects including Mathematics, Ancient or Modern Foreign Language, Science, etc.

The history of ethanol as a fuel spans several centuries and is marked by a series of significant milestones. Samuel Morey, an American inventor, was the first to produce ethanol by fermenting corn in 1826. However, it was not until the California Gold Rush in the 1850s that ethanol was first used as a fuel in the United States.
