Creating a 3D chiral microenvironment using gelators enhanced lipase biocatalysis. Right-handed helical nanostructures boosted lipase activity up to 10-fold, showing promise for enzyme immobilization.
Area of Science:
- Biocatalysis and Enzyme Engineering
- Materials Science
- Chiral Chemistry
Background:
- The influence of three-dimensional (3D) chiral environments on biocatalysis is crucial for developing effective enzyme immobilization strategies.
- Mimicking natural enzyme microenvironments is key to enhancing biocatalytic efficiency.
Purpose of the Study:
- To design and construct a 3D chiral catalytic microenvironment using gelators with d/l-phenylalanine chiral centers.
- To investigate the impact of this chiral microenvironment on lipase biocatalysis.
Main Methods:
- Development of two gelators incorporating d/l-phenylalanine as chiral centers.
- Programming a 3D chiral microenvironment through chiral transmission from molecular chirality to achiral polymers.
- Immobilization of lipase within the constructed microenvironments.
Main Results:
- The chirality of the microenvironment significantly influenced immobilized lipase catalytic efficiency.
- A 3D microenvironment with right-handed helical nanostructures enhanced lipase activity by up to 10-fold for 4-nitrophenyl palmitate (NPP) hydrolysis.
- A 1.4-fold increase in catalyzing lipids to triglycerides (TGs) was observed in 3T3-L1 cells.
- The chiral microenvironment demonstrated good catalytic efficiency, high storage stability, and recyclability.
Conclusions:
- The designed 3D chiral microenvironment effectively enhances lipase biocatalysis.
- This strategy overcomes limitations of traditional enzymatic immobilization materials.
- The findings deepen the understanding of biocatalysis in chiral environments.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
