Fig. 6: Esterification reaction performances.

a The principle of the esterification reaction. b The time-dependent 1H NMR (CDCl3) spectra of the esterification reaction between oleic acid and n-decanol by LA-n-prop@Zn-HHTP biocatalyst. The Lipase TL was normalized to 1 mg/mL in the reaction system. c Time-dependent yield of decyl oleate and conversion of oleic acid based on 1H NMR using LA-n-prop@Zn-HHTP and native Lipase TL as the catalysts, respectively. Error bars = standard deviation (SD); Data were presented as mean values ± SD (n = 3; n presents the sample size used to derive statistics). d Recyclability of LA-n-prop@Zn-HHTP catalyst for esterification reaction. Error bars = standard deviation (SD); Data were presented as mean values ± SD (n = 3; n presents the sample size used to derive statistics). e The esterification yield of Lipase TL and LA-n-prop@Zn-HHTP for pentanol and oleanol. Error bars = standard deviation (SD); Data were presented as mean values ± SD (n = 3; n presents the sample size used to derive statistics). Source data are provided as a Source Data file.
