Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Aquaculture Nutrition called Dietary fishmeal levels affect anti-oxidative ability and metabolomics profile of juvenile Pacific white shrimp, Litopenaeus vannamei, Author is Xie, Shi-wei; Wei, Dan; Chen, Shi-jun; Zhuang, Zhenxiao; Yin, Peng; Liu, Yong-jian; Tian, Li-xia; Niu, Jin, which mentions a compound: 1824-94-8, SMILESS is O[C@H]([C@H]([C@H]([C@@H](CO)O1)O)O)[C@@H]1OC, Molecular C7H14O6, Safety of (2R,3R,4S,5R,6R)-2-(Hydroxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol.
In this manuscript, three iso-nitrogenous and iso-lipidic diets containing 50, 150 and 250 g/kg of fishmeal (FM) were fed white shrimp Litopenaeus vannamei for 8 wk. At the end of feeding, survival and percentage weight gain of shrimp were examined Hepatopancreas and haemolymph were sampled, activities of superoxide dismutase (SOD) and catalase (CAT), nitric oxide (NO), glutathione (GSH) and malondialdehyde (MDA) levels in hepatopancreas, activities of SOD, CAT, acid phosphatase (ACP) and alk. phosphatase (AKP), and NO, GSH, MDA in haemolymph were examined Haemolymph was further subjected to GC-MS anal. Results indicated that no significant differences in survival rate and percentage weight gain were observed among three treatments. SOD activity and GSH levels in hepatopancreas, and CAT activity, AKP activity, GSH and MDA levels in haemolymph were significantly lower in shrimp fed 50 g/kg FM diet. GC-MS anal. of haemolymph indicated that 81 metabolites were significantly altered in the three groups. Furthermore, 8 metabolism pathways were significantly influenced by dietary FM levels. In conclusion, dietary administration of 50 g/kg FM resulted in inhibition of antioxidant ability, and disordered the energy metabolism, one-carbon metabolism and unsaturated fatty acid metabolism in shrimp.
As far as I know, this compound(1824-94-8)Safety of (2R,3R,4S,5R,6R)-2-(Hydroxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
