Organic chemistry is based on the classical concept of the molecule, which postulates that molecules have distinct physical shapes, sizes, structures, and are composed of atoms and chemical bonds. Although this concept is not consistent in some respects with what is suggested by quantum mechanics, it reveals a novel property of molecules: molecules are designable. Thanks to this property we can synthesize chemical compounds as we desire with precise control of molecular transformations. Organic synthesis, especially the highly selective synthesis of chiral substances, demonstrates that this concept is empirically adequate. It is also shown that organic chemistry is rational and autonomous as a science with regard to the Method of Analysis and Synthesis.© 2013 by HYLE and OCHIAI Hirofumi. Source

The hydration structure of starch molecule in Domyoji-ko, which is made from gluey rice, was investigated by hetero 2D correlation analysis of IR and NIR spectroscopy. The feature near 1020 cm-1 in the IR spectra of Domyoji-ko is changed by rehydration process, indicating that the molecular structure of amylopectin in the starch has been varied by the hydration without heating. The intensity of a band at 4770 cm-1 in NIR spectra is decreasing with the increasing of either the heating time with water or rehydration time without heating. These results suggest that the hydration of Domyoji-ko has proceeded in similar mechanisms on these processes. The generalized hetero 2D IR-NIR correlation analysis for rehydration of Domyoji-ko has supported the assignments for NIR bands concerning the gelatinization of starch. © 2010 Elsevier B.V.

Background/Objectives: We examined the association between 24-h urinary excretion of water-soluble vitamin levels and their intakes in free-living Japanese university students. The design used was cross-sectional study. Subjects/Methods: A total of 216 healthy, free-living male and female Japanese university students aged 18-27 years voluntarily participated in this study, of which 156 students were eligible for this assessment. All foods consumed for 4 consecutive days were recorded accurately by a weighed food record method. A 24-h urine sample was collected on the fourth day, and the urinary levels of water-soluble vitamins were measured. Results: Each urinary water-soluble vitamin level, except for vitamin B 12, was correlated positively with its mean intake in the recent 2-4 days (vitamin B 1: r0.42, P0.001; vitamin B 2: r0.43, P0.001; vitamin B 6: r0.40, P0.001; vitamin B 12: r0.06, P0.493; niacin: r0.35, P0.001; niacin equivalents: r0.33, P0.001; pantothenic acid: r0.47, P0.001; folate: r0.27, P0.001; vitamin C: r0.44, P0.001). Mean estimated water-soluble vitamin intakes calculated from urinary levels and recovery rates showed 91-101% of their 3-day mean intakes, except for vitamin B 12 (61%). Conclusions: These results showed that urinary water-soluble vitamin levels, except for vitamin B 12, reflect their recent intakes in free-living Japanese university students, and could be used as a potential biomarker to estimate mean vitamin intake. © 2010 Macmillan Publishers Limited All rights reserved.

Stereochemistry studies molecules and molecular transformations by way of the classical model of the molecule, which envisages molecules as composed of atoms that are linked together by chemical bonds. The underlying hypothesis of this model is that molecules are entities with definite shape and structure, and behave like mechanical objects in the world of possible experience. Such a view of molecules raises questions about the legitimacy of this science because neither shape nor structure is taken any longer as a solid scaffold on which to construct philosophical or scientific arguments. Thus, questions to be addressed in this paper are whether or not it is allowed to treat molecular events, which are dynamic in nature and subject to quantum mechanical principles, by way of the classical model; whether or not the classical model is proved true by the physical measurements of molecules; and whether or not the nature of enantiomers is explicable by the classical model. An analytical tool kit for the philosophy of chemistry recently introduced by Harré (the concept of the affordance in particular) will help to prove the empirical adequacy of the classical model. Inquiries into these questions from a philosophical as well as from a chemical point of view will reveal the foundations of stereochemistry. © 2015 by HYLE and Hirofumi OCHIAI. Source

Copper chaperone for superoxide dismutase (CCS) is essential for transporting copper ion to Cu,Zn-superoxide dismutase (Cu,Zn-SOD). We cloned cDNAs for six primate species' CCSs. The total number of amino acid residues of primate CCSs is 274. Similarities between primates were over 96%. Important residues for the CCS function were well conserved. A phylogenetic tree of CCSs and Cu,Zn-SODs from various organisms showed that these two proteins were derived from a common ancestor, diverging very early on during eukaryote evolution. The high frequency of nonsynonymous substitutions was found in the lineage to Old World monkeys and apes. Expression of the CCS gene in various tissues of Japanese monkey was found to be high in the liver and adrenal gland, followed by the kidney and small intestine. Such expressional pattern was similar with that of Cu,Zn-SOD gene (Fukuhara et al., 2002). © 2012 Elsevier B.V. Source
