Original abstract
The reported decline of plasmalogens over the aging process has been implicated as a contributing factor in some neurogenerative diseases and cognitive decline, e.g., Alzheimer's and Parkinson's diseases. Dietary marine plasmalogen supplementation has been shown to improve cognition (memory). This study showed that bovine milk (BM) is also a potential source of dietary plasmalogens, containing ethanolamine plasmalogen (EtPlas) levels ranging from 4.3 to 7.1 μg mL⁻¹. These plasmalogens are enriched in human milk (HM) and milk fat globule membrane (MFGM) isolates. The average EtPlas levels in HM samples were 16.8 ± 7.5 μg mL⁻¹ and the most abundant EtPlas molecular species was C16:1/C20:4 (11.5 %); in bovine raw milk and MFGM isolates it was C16:1/C18:1 (19.0–25.9 %). EtPlas contributed to 20.7 % of total phosphatidylethanolamine in HM compared with 4 %–5 % for BM and MFGM isolates.
