Phenylglycine is the organic compound with the formula C 6 H 5 CH(NH 2)CO 2 H. It is a non-proteinogenic alpha amino acid related to alanine, but with a phenyl group in place of the methyl group. It is a white solid. The compound exhibits some biological activity. [1]
N-Phenylglycine is an organic compound with the formula C 6 H 5 NHCH 2 CO 2 H. This white solid achieved fame as the industrial precursor to indigo dye . [ 1 ] It is a non-proteinogenic alpha amino acid related to sarcosine , but with an N - phenyl group in place of N - methyl .
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
Biosynthesis of HPG. HPG is synthesized from prephenate, an intermediate in the shikimic acid pathway and also a precursor to tyrosine.Prephenate is aromatized by prephenate dehydrogenase (Pdh) using NAD + as a cofactor to produce 4-hydroxyphenylpyruvate. 4-Hydroxyphenylpyruvate is then oxidized by 4-hydroxymandelate synthase (4HmaS) using oxygen to form 4-hydroxymandelate and hydrogen ...
N-phenylsydnone was first prepared in 1935 by John Campbell Earl and Alan W. Mackney [Wikidata] by cyclodehydration of N-Nitroso-N-phenylglycine with acetic anhydride. [4] Later work showed that this could be applied fairly generally to the nitrosamines of N-substituted amino acids .
[1] [2] Azlactone chemistry: step 2 is a Perkin variation. Hippuric acid, the benzamide derivative of glycine, cyclizes in the presence of acetic anhydride, condensing to give 2-phenyl-oxazolone. [3] This intermediate also has two acidic protons and reacts with benzaldehyde, acetic anhydride and sodium acetate to a so-called azlactone.
In organic chemistry, functionality is often used as a synonym for functional group. For example, a hydroxyl group can also be called a HO-function. [1] [2] Functionalisation means the introduction of functional groups, for example the functionalisation of a surface [3] (e.g. silanization for the specific modification of the adhesion of a surface)
[1] (S)-DHPG has been investigated for therapeutic effects in the treatment of neuronal injury (such as those associated with ischemia or hypoxia), cognitive enhancement, and Alzheimer's disease. [1] 3,5-Dihydroxyphenylglycine can be isolated from the latex of Euphorbia helioscopia. [2] DHGP is also found in vancomycin and related glycopeptides.
