Invertin
IUPAC 名称
(4S,4aR,5S,5aR,6R,12aS)-4-(dimethylamino)-3,5,10,12,12a-pentahydroxy-6-methyl-1,11-dioxo-1,4,4a,5,5a,6,11,12a-octahydrotetracene-2-carboximidic acid hydrate
描述
Invertin, also known as doxycycline or monodox, is a member of the class of compounds known as tetracyclines. Tetracyclines are polyketides having an octahydrotetracene-2-carboxamide skeleton, substituted with many hydroxy and other groups. Invertin is practically insoluble (in water) and an extremely strong acidic compound (based on its pKa). Invertin can be found in common verbena, which makes invertin a potential biomarker for the consumption of this food product. Invertin is an enzyme that catalyzes the hydrolysis (breakdown) of sucrose (table sugar). Alternate names for invertase include EC 3.2.1.26, saccharase, glucosucrase, beta-h-fructosidase, beta-fructosidase, invertin, sucrase, maxinvert L 1000, fructosylinvertase, alkaline invertase, acid invertase, and the systematic name: beta-fructofuranosidase. The resulting mixture of fructose and glucose is called inverted sugar syrup. Related to invertases are sucrases. Invertins and sucrases hydrolyze sucrose to give the same mixture of glucose and fructose. Invertins cleave the O-C(fructose) bond, whereas the sucrases cleave the O-C(glucose) bond .
