Ascorbic acid or vitamin C is a monosaccharide oxidation-reduction (redox) catalyst found in both animals and plants.[76] As one of the enzymes needed to make ascorbic acid has been lost by mutation during primate evolution, humans must obtain it from their diet; it is therefore a dietary vitamin.[76][77] Most other animals are able to produce this compound in their bodies and do not require it in their diets.[78] Ascorbic acid is required for the conversion of the procollagen to collagen by oxidizing proline residues to hydroxyproline.[76] In other cells, it is maintained in its reduced form by reaction with glutathione, which can be catalysed by protein disulfide isomerase and glutaredoxins.[79][80] Ascorbic acid is a redox catalyst which can reduce, and thereby neutralize, reactive oxygen species such as hydrogen peroxide.[76][81] In addition to its direct antioxidant effects, ascorbic acid is also a substrate for the redox enzyme ascorbate peroxidase, a function that is used in stress resistance in plants.[82] Ascorbic acid is present at high levels in all parts of plants and can reach concentrations of 20 millimolar in chloroplasts.
Explanation:the local and state governments use their taxes to pay taxes to the national government. each level of government equally provides revenue for every service in the united states. different levels of government provide different services that must be paid for by taxes.
By protecting intellectual property, we made a specific invention could only be produced by the inventors alone.
Which means that the companies in other countries do not possess the right to produce it. This will increase the GDP of the country where the inventors came from
Individuals migrate because they think that they can improve their own lives or those of their families by doing so. Economic migration is triggered by the knowledge (or belief) that better economic opportunities exist in some other place.
Conflicts are inevitable. They are part of all relationships between individuals who work together. ... Conflict is internal discord that occurs because of a difference in ideas, values or perceptions or in the interpretation of a situation
