Stygivenator molnari. (Paul, 1988a emend Paul, 1990) Olshevsky, 1995. Tyrannosaurus ( / tɪˌrænəˈsɔːrəs, taɪ -/) [a] is a genus of large theropod dinosaur. The type species Tyrannosaurus rex ( rex meaning "king" in Latin ), often shortened to T. rex or colloquially T-Rex, is one of the best represented theropods.
Amino acids can be classified according to the locations of the core structural functional groups ( alpha- (α-), beta- (β-), gamma- (γ-) amino acids, etc.), other categories relate to polarity, ionization, and side chain group type ( aliphatic, acyclic, aromatic, polar, etc.). In the form of proteins, amino acid residues form the second ...

Pure MSG is reported not to have a highly pleasant taste until it is combined with a savory aroma. The basic sensory function of MSG is attributed to its ability to enhance savory taste-active compounds when added in the proper concentration. The optimal concentration varies by food; in clear soup, the "pleasure score" rapidly falls with the additi...
MSG is generally recognized as safe to eat. A popular belief is that MSG can cause headaches and other feelings of discomfort, but blinded tests have not provided strong evidence of this. International bodies governing food additives currently consider MSG safe for human consumption as a flavor enhancer. Under normal conditions, humans can metaboli...
MSG has been produced by three methods: hydrolysis of vegetable proteins with hydrochloric acid to disrupt peptide bonds (1909–1962); direct chemical synthesis with acrylonitrile (1962–1973), and bacterial fermentation (the current method). Wheat gluten was originally used for hydrolysis because it contains more than 30 g of glutamate and glutamine...
The compound is usually available as the monohydrate, a white, odorless, crystalline powder. The solid contains separate sodium cations Na+ and glutamate anions in zwitterionic form, −OOC-CH(NH+ 3)-(CH2)2-COO−. In solution it dissociatesinto glutamate and sodium ions. MSG is freely soluble in water, but it is not hygroscopic and is insoluble in com...
Glutamic acid was discovered and identified in 1866 by the German chemist Karl Heinrich Ritthausen, who treated wheat gluten (for which it was named) with sulfuric acid. Kikunae Ikeda of Tokyo Imperial University isolated glutamic acid as a taste substance in 1908 from the seaweed Laminaria japonica (kombu) by aqueous extraction and crystallization...

Agent Orange is a chemical herbicide and defoliant, one of the tactical use Rainbow Herbicides . It was used by the U.S. military as part of its herbicidal warfare program, Operation Ranch Hand, [1] during the Vietnam War from 1961 to 1971. [2] It is a mixture of equal parts of two herbicides, 2,4,5-T and 2,4-D.
