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 .
Phytochemistry is the study of phytochemicals, which are chemicals derived from plants.Phytochemists strive to describe the structures of the large number of secondary metabolites found in plants, the functions of these compounds in human and plant biology, and the biosynthesis of these compounds.
Naturally occurring phenethylamines are organic compounds which may be thought of as being derived from phenethylamine itself that are found in living organisms. Tyramine is a phenethylamine that occurs widely in plants [ 1 ] and animals , and is metabolized by various enzymes , including monoamine oxidases .
Phytogeography (from Greek φυτόν, phytón = "plant" and γεωγραφία, geographía = "geography" meaning also distribution) or botanical geography is the branch of biogeography that is concerned with the geographic distribution of plant species and their influence on the earth's surface. [1]
The phenolic unit can be found dimerized or further polymerized, creating a new class of polyphenol. For example, ellagic acid is a dimer of gallic acid and forms the class of ellagitannins, or a catechin and a gallocatechin can combine to form the red compound theaflavin, a process that also results in the large class of brown thearubigins in tea.
Phytochemicals are chemicals of plant origin. [1] Phytochemicals (from Greek phyto, meaning "plant") are chemicals produced by plants through primary or secondary metabolism. [2] [3] They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators. [2]
4-Hydroxyphenylglycine (HPG) is a non-proteogenic amino acid found in vancomycin and related glycopeptides. HPG is synthesized from the shikimic acid pathway and requires four enzymes to synthesize: [1] Both L- and D-HPG are used in the vancomycin class of antibiotics.
