In this study, waste shrimp shells from industry were used as a heterogeneous bio-based catalyst for trans-esterification reaction of fresh palm oil. CaO was prepared calcination. Surface area, phase composition, and basicity the calcined shell catalysts studied using N2 adsorption (BET), X-ray diffraction (XRD), CO2 temperature-programmed-desorption (CO2-TPD), respectively. The influence calci...
Biotransformation of nerol by larvae of the common cutworm (Spodoptera litura) was investigated. The resulting major metabolites were (2Z,6E)-1-hydroxy-3,7-dimethyl-2,6-octadien-8-oic acid and 8-hydroxynerol, and the minor metabolites were 9-hydroxynerol and (2Z,6E)-1-hydroxy-3,7-dimethyl-2,6-octadien-8-al. (2Z,6E)-1-Hydroxy-3,7-dimethyl-2,6-octadien-8-oic acid is a novel compound. The results ...
9-Hydroxy-4,8-dimethyl-12-(pyrrolidin-1-ylmethyl)-3,14-dioxatricyclo[9.3.0.02,4]tetradec-7-en-13-one
Two new polyketides: 2Z-(heptadec-12-enyl)-4-hydroxy-3,4,7,8-tetrahydro-2H-chromen-5(6H)-one (1) and 2-(heptadec-12-enyl)-5-hydroxy-5,6,7,8-tetrahydrochromen- 4-one (2), together with eleven known compounds: 4-hydroxy-2-[(3,4-methylenedioxy- phenyl)tridecanoyl] cyclohexane-1,3-dione (3), oleiferinone (4), 4-hydroxy-2-[(3,4- methylenedioxyphenyl)undecanoyl]cyclohexane-1,3-dione (5), 4-hydroxy-2-...
Abstract Microalgal lipids and fatty acids are important components for achieving biofuel because of their potential high productivity. Although that have a hydroxy group adjacent to the end acyl chain might be an chemical feedstock, most algae do not accumulate it. To produce (ω−1)-hydroxy from 3-hydroxybutylyl-CoA, intermediate polyhydroxybutylate biosynthesis in cyanobacterium Synechocystis ...
