摘要： Provided is a novel cellulose derivative having excellent water resistance. This is a cellulose acylate oxoalkanoate which is a cellulose derivative corresponding to cellulose, except with substituents replacing part or all of hydrogen atoms in the hydroxy groups of the cellulose. The substituents includes a group represented by General Formula (1) and a group represented by General Formula (2). The cellulose acylate oxoalkanoate has a degree x of substitution with the group represented by General Formula (1), a degree y of substitution with the group represented by General Formula (2), and a degree z of unsubstitution, where x, y, and z meet conditions specified by Expressions (A), (B), and (C): 0.1≦x≦2.99 (A) 0.01≦y≦2.90 (B) z=3−x−y (C)

摘要： A nutrient composition, a lipid metabolism-improving agent, and prophylactic and/or therapeutic agents typically for inflammatory bowel diseases, immune disorders, cancers, non-alcoholic steatohepatitis, obesity, diabetes, and hypercholesterolemia each contain a cellulose acetate having a total degree of acetyl substitution of 0.4 to 1.1. The cellulose acetate may be one having a compositional distribution index (CDI) of 2.0 or less, where the CDI is defined by the formula: CDI=(Measured value of half height width of chemical composition)/(Theoretical value of half height width of chemical composition) where the measured value of half height width of chemical composition represents a half height width of chemical composition determined by HPLC analysis of a cellulose acetate propionate prepared by propionylating all residual hydroxy groups of the cellulose acetate (sample), and the theoretical value of half height width of chemical composition=2.35482√{square root over (3*DPw*(DS/3)*(1−DS/3))}/DPw [Math. 1] where DS is the total degree of acetyl substitution; and DPw is a weight-average degree of polymerization determined by a GPC-light scattering method using a cellulose acetate propionate prepared by propionylating all residual hydroxy groups of the cellulose acetate (sample).
