Because of the acid-catalyzed mechanism of both hydrolysis of inulin and dehydration of fructose, these two processes can be integrated in one pot. Hu et al. [47] conducted the efficient one-pot reaction for the conversion of inulin into 5- HMF with ChCl:oxalic acid and ChCl:citric acid...
tunable electrical and thermal conductivities, and low density. Graphene’s sulfonation creates Brønsted acid sites turning it into a promising solid acid catalyst for the hydrolysis of cellulose or carbohydrates toward industrially essential chemicals. Sulfonic acid-...
Explain using isotopic oxygen (O18) the basic hydrolysis mechanism of ester and the position of the oxygen labeled during the reaction. (Hint: Rely on the relative basicity of the nucleophile and the leaving group in this response.) a. Write the reaction between formic acid and water....
Although it was assumed that the formation of two distinct liquid phases would disrupt the reaction equilibrium, the jump in yield upon reaching 373 K suggests that at lower temperatures the hydrolysis of the ester product is only discouraged and the reversible reaction not fully eliminated. It is...
Acetylated cellulose having reduced DS values can be prepared by controlled partial hydrolysis of cellulose triacetate. Typically, acetylated cellulose is prepared by reacting cellulose with an acetylating agent in the presence of a suitable acidic catalyst. In most cases, the cellulose is exhaustively ...

Of these isoforms, SNAT1 and SNAT2 share extensive similarities in substrate profiles and transport mechanism, although SNAT2 is more widely expressed than SNAT1. SNAT4 also transports cationic amino acids, independent of Na+, and is predominantly expressed in the liver. However, all SNAT ...
Focusing on a digestion mechanism in the case of oral intake, they evaluated the functions of the complex by an artificial gastric fluid treatment including pepsin (pepsin treatment), which is a model of the stomach as the digestive organ. Furthermore, it is considered that since protamine is ...
