ABSTRACT
BACKGROUND: Lipids and carbohydrates perform essential functions in foods. In recent decades, food scientists have studied the effects of carbohydrate-lipid interactions on the functional properties of food. However, the ways in which carbohydrate-lipid complex-derived materials affect the biological system are unknown. In this study, a myristic acid-potato starch complex was created using a simple cooking approach. The complex was employed as a precursor for the fabrication of myristic acid-potato starch complex-based nanostructured materials (MPS-NMs) through a liquid-liquid extraction approach. A study was conducted on the structural and cytotoxic features of the fabricated MPS-NMs. RESULTS: Transmission electron microscopy images confirmed the formation of spherical nanostructures, 3-60 nm in size. After 24 h exposure, the chloroform fraction-based and n-hexane fraction-based MPS-NMs increased cell death by ~90% and ~ 82%, respectively. Chloroform fraction-based MPS-NMs (CMPS-NMs) triggers apoptotic cell death in human mesenchymal stem cells (hMSCs). n-Hexane fraction-based MPS-NMs (HMPS-NMs) treated cells have red color-intact nuclei, attributed to necrotic cell death. The CMPS-NMs and HMPS-NMs significantly decreased the mitochondria membrane potential and increased the intracellular reactive oxygen species (ROS) levels. We observed significant downregulation in flavin-containing monooxygenase (FMO), Ataxia Telangiectasia Mutated (ATM), and uridine diphosphate glucuronosyltransferases (UGT) gene expression levels in the exposed cells of CMPS-NMs and HMPS- NMs. In addition, we found upregulation of glutathione-disulfide reductase (GSR) and glutathione S-transferase A4 (GSTA4) genes in CMPS-NMs, and HMPS-NMs exposure. CONCLUSION: The cooking process may lead to the formation of nanostructured material in food systems. Chloroform fraction-based MPS-NMs and HMPS-NMs may contribute to cell metabolic disorders. © 2023 Society of Chemical Industry.
