Protein-lipid complexes in industrial and biological systems

PhD defence, Friday 27 January 2023. Helena Østergaard Rasmussen.

Helena Østergaard Rasmussen

During her PhD studies, Helena Østergaard Rasmussen investigated how industrial enzymes and amyloid proteins interact and form complexes with lipids. Amyloid proteins form large robust structures called fibrils. They are involved in Alzheimer’s and Parkinson’s disease where the formation of fibrils damages the brain cells. The fibril structure can also be utilized in a functional manner for forming a protective layer for bacteria or storing hormones in humans. Understanding protein-lipid complex formation is important for product development for example for laundry detergent formulations and for understanding the mechanisms of amyloid fibril formation.


The PhD study was completed at Interdisciplinary Nanoscience Center (iNANO), Faculty of Natural Sciences, Aarhus University and at Department of Life Sciences, Faculty of Natural Sciences, Imperial College London.

This summary was prepared by the PhD student.
