ATP 8.1.1 State that oxidation involves the loss of electrons from an element‚ whereas reduction involves a gain of electrons; and that oxidation frequently involves gaining oxygen or losing hydrogen‚ whereas reduction frequently involves losing oxygen or gaining hydrogen. Oxidation: gain oxygen / lose hydrogen / lose electrons Reduction: lose oxygen / gain hydrogen / gain electrons 8.1.2 Outline the process of glycolysis‚ including phosphorylation‚ lysis‚ oxidation and ATP formation.

antioxidant are used widely in the production of food which fats and oils are used as raw materials and in the marketing of foods containing fats under modern conditions. The major factor in quality degradation of fats and fatty portions of foods is oxidation. In the oxidative deterioration of fats and fat-like substances‚ off-flavors and off-odors are usually reported. Rather than the breakdown of the unsaturated fat molecules‚ there are four types of fat deterioration. Hydrolysis is the formation of

Main factors affect the refined oil yield: 1‚ the alkali refining loss (1) for removal of colloid in hair oil‚ free fatty acid‚ moisture‚ impurities and other form of loss; (2) in the process caused by the loss of neutral oil saponification‚ emulsification; (3) theoretical calculation formula: alkali refining losses = 0.2 + 1.25 x (FFA % % + water + phosphatide content % % + 0.3% + impurities) 2‚ decoloring loss mainly for adsorption bleaching waste clay in oil absorption caused by the loss

Chemical composition of the essential oil of Majorana hortensis grown in Uttaranchal Shishir Kumar Singh Abstract GLC and GC-MS Analysis was done to analyse the hydrodistilled essential oil of Majorana hortensis grown in Uttranchal state of India. The 36 compounds could be identified out of 50 by their mass spectra accounting for 93% of the oil. The major ones are trans-sabinene hydrate (41.2%)‚ terpinen-4-ol (18.5%)‚ cis-sabinene hydrate (9.3%)‚ a-terpineol (3.8%)

the balanced chemical equation for the decomposition of water to its elements. 2H2O(l) 2H2(g) + O2(g) 2. (a) Assign oxidation states to the hydrogen and oxygen atoms in each substance in the above chemical equation. The oxidation state of H2(g) and O2(g) is zero‚ because they are in their normal state. (b) Based on the changes in oxidation states for each atom‚ identify the atom that is oxidized and the atom that is reduced in the decomposition of water. Hydrogen atom is reduced

reactions. They are also known as oxidation-reduction reactions. This reaction passes one or more electrons from one species to another. The species that loses electrons are being oxidized while the species that gains electrons are reduced. The reaction occurs simultaneously. Numbers are given to each element in a chemical reaction to help us find out which element is oxidized and which is reduced. According to the Error: Reference source not foundduring a reaction‚ the oxidation number of an element increases
