Isoelectronicity is a phenomenon observed when two or more molecules have the same structure (positions and connectivities among atoms) and the same electronic configurations, but differ by what specific elements are at certain locations in the structure. For example, CO, NO +, and N 2 are isoelectronic, while CH 3 COCH 3 and CH 3 N = NCH 3 are ...
Some chemicals found in trace amounts in food, as well as some dietary supplements, have been shown to inhibit 5-LOX; these include baicalein, caffeic acid, curcumin, [3] hyperforin and St John's wort. [8] [9] [10]
In drug discovery, either a large series of structural analogs of an initial lead compound are created and tested as part of a structure–activity relationship study [5] or a database is screened for structural analogs of a lead compound. [6] Chemical analogues of illegal drugs are developed and sold in
Although food engineering is a relatively recent and evolving field of study, it is based on long-established concepts and activities. [1] The traditional focus of food engineering was preservation, which involved stabilizing and sterilizing foods, preventing spoilage, and preserving nutrients in food for prolonged periods of time. [5]
Food storage and preservation is a key component of food engineering processes and relies heavily on biological engineering to understand and manipulate the organisms involved. Note that the above food safety processes such as pasteurization and sterilization destroy the microorganisms that also contribute to deterioration of food products ...
In chemistry, azide (/ ˈ eɪ z aɪ d /, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure − N=N + =N −.It is the conjugate base of hydrazoic acid HN 3. Organic azides are organic compounds with the formula RN 3, containing the azide functional group. [1]
As indicated above, some mammals typically used for food production (such as goats, sheep, pigs, and cows) have been modified to produce non-food products, a practice sometimes called pharming. Use of genetically modified goats has been approved by the FDA and EMA to produce ATryn, i.e. recombinant antithrombin, an anticoagulant protein drug. [20]
Metabolic engineering specifically seeks to mathematically model these networks, calculate a yield of useful products, and pin point parts of the network that constrain the production of these products. [1] Genetic engineering techniques can then be used to modify the network in order to relieve these constraints. Once again this modified ...
