不同离子对核桃蛋白结构及功能特性的影响Effects of different ions on the structure and functionality of walnut protein
Zhongguo youzhi为了有效提高核桃蛋白的利用率，拓展核桃蛋白在食品领域的应用范围，采用阴离子（Cl-、PO3-4、S2O2-3、HCO-3）和阳离子（Na+、K+、Mg2+、Ca2+）对核桃蛋白进行改性，并对改性后核桃蛋白的结构与功能特性进行研究。结果显示：阴离子PO3-4、HCO-3 和阳离子Na+、Mg2+增加了核桃蛋白的巯基含量；除了Cl-和K+，其他6种离子改性核桃蛋白的二硫键含量均下降，其中HCO-3改性核桃蛋白下降最多；8种离子对核桃蛋白的亚基组成无影响；Cl-、PO3-4、Na+和Ca2 ...

Disc‐Toroid Hybrid Lipid Nanoparticles for Efficient Drug Encapsulation and Subcutaneous Delivery
Small, EarlyView.This study demonstrates sub‐50 nm solid‐lipid nanoparticles with long‐term stability, high drug loading, and strong tissue compatibility. Disc‐toroid morphology is confirmed and may play a role in cellular interactions, while low cytotoxicity and minimal systemic permeation confirm depot‐like behavior. These nanoparticles represent a versatile platform
