Protein oxidation results in structural modification which affects its digestion. The objective of this work was to investigate the influence of lipoxygenases (LOX) catalyzed linoleic acid (LA) oxidation on the structure and in vitro gastric digests of soybean protein isolate (SPI). Fluorescence recovery after photobleaching (FRAP) was used to evaluate the relationship between pepsin diffusion and gastric digestion. Results indicated that oxidation induced carbonyl formation and loss of free sulfhydryl. Increased surface hydrophobicity and zeta-potential verified the protein unfolding and thus resulted in a small particle size and low fluorescence intensity. Fourier transform infrared spectroscopy (FTIR) showed that oxidation caused the increases in beta-sheets mostly at the expense of alpha-helix and random coils. Fluorescein isothiocyanate (FITC)-pepsin in SPI solution modified with 3 mL LA showed a faster diffusion rate with 80.51 mu m(2)/s as well as a higher DH value of 9.11%, showing that pepsin diffusivity might play an important role in protein gastric digestion.

Protective Effects of Natural Polysaccharides on Intestinal Barrier Injury: A Review

Jiaying Huo, Ziyan Wu, Weizheng Sun, Zhenhua Wang, Jihong Wu, Mingquan Huang, Bowen Wang, Baoguo Sun

Summary: This review examines the protective effects of natural polysaccharides (NPs) as adjuvant therapy for diseases caused by intestinal barrier injury (IBI). NPs are found to minimize oxidative stress, inflammation, and malignant growth, making them a potential treatment option for IBI-related diseases. The review discusses the potential mechanisms of NPs in directly maintaining intestinal barrier integrity and indirectly regulating intestinal immunity and microbiota. It also highlights the structure-activity relationships of polysaccharides and the potential challenges associated with using NPs in the treatment of IBI-induced intestinal diseases.

Environmental performance of an urban passenger transport system and influencing factors: A case study of Tianjin, China

Yin Cui, Zhiyong Li, Yu Sun, Weizheng Sun

Summary: This paper analyzes the interaction between the environmental performance of an urban passenger transport system (EPUPTS) and its influencing factors using Tianjin, China as an example. The EPUPTS in Tianjin is evaluated and a vector auto-regression model is used to analyze the dynamic relationship between the environmental performance, inputs, and inputs of transportation facility manufacturers. The results show that the EPUPTS in Tianjin is stable but still has room for improvement, and the input of passenger transport vehicles has a significant impact on the environmental performance.

Heteroprotein complex between soy protein isolate and lysozyme: Protein conformation, lysozyme activity, and structural characterization

Jiabao Zheng, Chuan-he Tang, Jihong Wu, Ge Ge, Mouming Zhao, Weizheng Sun

Summary: Heteroprotein complexes are formed through electrostatic interactions in a purely aqueous environment. This study investigated the structural and functional properties of soy protein isolate/lysozyme (SPI/LYS) complexes. Electrostatic complexation increased the surface hydrophobicity of the complexes, but it did not decrease the enzyme activity of lysozyme. The complexes exhibited flocculated structures and high dilution and NaCl reduced their size.

The influence of protein oxidation on structure, pepsin diffusion, and in vitro gastric digestion of SPI emulsion

Jie Zhao, Shuaiqian Wang, Diandian Jiang, Chong Chen, Jie Tang, Igor Tomasevic, Weizheng Sun

Summary: The effects of oxidized SPI emulsions on in vitro gastric stability and pepsin diffusion were investigated. The results showed that protein oxidation increased droplet size and decreased interfacial viscoelasticity. Pepsin diffusivity decreased due to the hindrance of oil droplets. After gastric digestion, protein hydrolysates formed a thick layer on the oil-water interface, reducing droplet size and free amino acid content. Protein oxidation affects interfacial protein adsorption and droplet distribution, impairing emulsion gastric digestion, which should be considered in the design of controllable delivery systems.
