Abstract: The present invention addresses the problem of providing a method for producing nicotinamide mononucleotide, that produces nicotinamide mononucleotide using a single enzyme and using nucleoside monophosphate, pyrophosphate, and nicotinamide as starting materials. This problem is solved by a nicotinamide mononucleotide production method that includes at least the following steps 1) and 2): 1) a first step of producing phosphoribosyl diphosphate by the action of substantially one enzyme on nucleoside monophosphate and pyrophosphate; and 2) a second step of producing nicotinamide mononucleotide by the action of only substantially the aforementioned one enzyme on nicotinamide and the phosphoribosyl diphosphate that is the product of the first step.

Abstract: It is intended to provide a noninvasive method of conveniently detecting mild impaired glucose tolerance and/or insulin hyposecretion at the early stage with the use of an enzyme. Namely, mild impaired glucose tolerance and/or insulin hyposecretion at the early stage are detected by quantifying myoinositol secreted into the urine before loading glucose and after loading glucose for a definite period of time with the use of a reagent and comparing the increase (or the increase ratio) in the myoinositol content thus measured with a characteristic level which has been preliminarily determined in normal subjects.

Abstract: A lignosellulose-phenolic compound composite product having a weight ratio of the lignocellulose material to the phenolic compound of 0.4/1.0 to 5.0/1.0 is prepared by heat-dissolving the lignocellulose material in a solvent comprising, as a main component, at least one phenolic compound, optionally in the presence of a dissolving acid catalyst, and then adjusting the amount of the phenolic compound to a level of 1/0.4 to 1/5.0 of the weight of the lignocellulose material, in which heat-dissolving step water generated, as a by-product, from the reaction of the lignocellulose material with the phenolic compound is preferably eliminated, to allow the temperature of the reaction system to rise and thus promote the heat-dissolving reaction.
