标题:Method for synthesis of anhydrothrombin
发明人：SUZUKI TOYOAKI; HOSOKAWA KAZUYA; NAGATA MASANORI
权利人:FUJIMORI KOGYO CO
摘要:A method for a synthesis of anhydrothrombin is provided which features a short process, an easy procedure, and high yields. n The method comprises n (A) a step of causing an active serine residue site of thrombin to react with an inhibitor, n (B) a step of performing an alkali treatment at a pH of not less than 11, and n (C) a step of performing an operation of recovery, and carries out these steps sequentially in the order mentioned, and is characterized by causing at least the step of performing the operation of recovery to proceed in the presence of at least one compound selected from the group consisting of polyhydric alcohols and saccharides, and a salt or an amphoteric electrolyte.

标题 :Enzymatic synthesis of acetoacetate esters and derivatives
发明人：HENDERSON SAMUEL T
权利人:HENDERSON SAMUEL T; ACCERA INC
摘要:In one embodiment, the present invention includes a method for the synthesis of an ester derivative of acetoacetate. The method includes providing a first ester of acetoacetate and providing an alcohol. The method further includes combining the first ester of acetoacetate and the alcohol in the presence of an enzyme capable of transesterification in a non-aqueous solvent to form the ester derivative of acetoacetate. The method results in the formation of the ester derivative of acetoacetate, which, in one embodiment, is monoacetoacetin.

权利人:HART CHERYLE RAM; GROSSMAN RONALD S; RAM HERBERT
摘要:Dietary supplements for treating a neurotransmitter deficiency include one or more precursors of the deficient neurotransmitter and a cofactor for activating in vivo enzymatic synthesis of the deficient neurotransmitter. The dietary supplements can also include an appropriate neurotransmitter, such as an amino acid. When administered through the oral mucosa, increases in levels of the deficient neurotransmitters and relief from deficiency symptoms are obtained.

标题 :Enzymatic synthesis of soluble glucan fiber
发明人：DICOSIMO ROBERT; CHENG QIONG; ELIOT ANDREW C; OUWEHAND ARTHUR; PAYNE MARK S; YOU ZHENG
权利人:DU PONT
摘要:An enzymatically produced soluble α-glucan fiber composition is provided suitable for use as a digestion resistant fiber in food and feed applications. The soluble α-glucan fiber composition can be blended with one or more additional food ingredients to produce fiber-containing compositions. Methods for the production and use of compositions comprising the soluble α-glucan fiber are also provided.
