Uses Cocarboxylase can be used in decarboxylation mechanisms in biological systems,and to investigate radical reactions of thiamin pyrophosphate in 2-oxoacid oxidoreductases. Definition The active coenzyme form of vitamin B1 which functions in aldehyde transfer reactions. Manufacturing Process 4.5 kg of aqueous 89% orthophosphoric acid are heated to 135°C, and kept at this temperature for about 3 h while being actively stirred. Then, the heating is discontinued and 3.5 kg of phosphorouspentoxide are added during a period of 2.5 to 3 h, while being actively stirred. During this period, the interior temperature rises to 165°-175°C. After completion of the addition of phosphorouspentoxide, the stirring is continued until all phosphorouspentoxide is dissolved. The phosphoric acid mixture thus produced is subsequently cooled down to 130°C. At this temperature 2.0 kg of thiamine chloride hydrochloride (vitamin B1) were added during 2 to 3 h while being well stirred. The stirring is continued at 130°C until the phosphorylated mixture no longer contains chlorine ions. A phosphorylated melt is thus obtained. The thus obtained phosphorylation melt is dissolved in 6-8 L of water (with ice) at a temperature below 10°C, while being vigorously stirred. The aqueous solution is stirred into 100 L of 96% alcohol and left standing overnight. The supernatant solvent is decanted from the separated syrup; the latter is taken up in 4 L of water. The solution thus obtained is fed, depending upon the volume of phosphoric acid contained therein, to an exchanger column filled with anion exchanger (weak basic, for instance Amberlite IRA 45, 20-30 L) (a polystyrene resin with primary, secondary and quaternary amino groups). The solution is caused to seep into the column from the top thereof and is then washed with water until the runoff at the bottom no longer shows any thiamine reaction. About 25 L of the solution are obtained, which are concentrated to 6 L at 30°C and 12 Torr. The concentrated residue is added to 20 to 30 L of a cationic exchanger (Amberlite IRC 50) in order to separate the thiamine-orthophosphoric acid ester from the thiamine-pyrophosphoric acid ester, and subsequently washed with water until the eluate is free of thiamine. 70-80 L of a solution are obtained which are concentrated to 1.5 L in a circulation evaporator at 30°C and 12 Torr. 7.5 L of 96% ethanol are slowly added to a concentrate while being stirred. The cocarboxylase-tetrahydrate separates in the form of fine needles. The yield is 530.0 g with a melting point of 220°-225°C (dec.). 10.0 g of cocarboxylase-tetrahydrate are dissolved in 25 ml of 5% aqueous hydrochloric acid, and 75 ml acetone are added dropwise while being stirred. The precipitated hydrochloride of the cocarboxylase, melting point 240°C is sucked off. The yield is 9.5 g. Therapeutic Function Coenzyme, Metabolic General Description Certified pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Thiamine pyrophosphate is a coenzyme of transketolase that catalyzes the cleavage of ribulose-5-phosphate; thereby forming D-glyceraldehyde-3-phosphate. This reaction requires the addition of an acceptor aldehyde such as ribose-5-phosphate, glyceraldehye or glycolaldehyde. Biochem/physiol Actions Thiamine pyrophosphate (TPP) is a coenzyme of transketolase, that catalyzes the cleavage of ribulose-5-phosphate. This reaction leads to the formation of D-glyceraldehyde-3-phosphate. It requires the addition of an acceptor aldehyde such as ribose-5-phosphate, glyceraldehye or glycolaldehyde. TPP is capable of decarboxylating hydroxypyruvate in the presence of an ′acceptor aldehyde′.   Cocarboxylase Preparation Products And Raw materials
