This handbook offers a detailed and application-oriented exploration of fish oil and lipid sources, examining their significance across nutritional, biochemical, and industrial domains. It presents a structured understanding of lipid substances, their origin, classification, and functional behaviour within biological and technological systems. The handbook places particular emphasis on extraction techniques, processing methods, and analytical approaches used to evaluate lipid quality and composition. It further engages with the role of lipids in human health, food production, and industrial utilisation, highlighting their importance in contemporary scientific and commercial contexts. In addition, the discussion considers the biochemical transformations and interactions of lipid compounds, enabling a clearer understanding of their behaviour within complex systems. The content is framed to encourage critical thinking and practical awareness of evolving developments in lipid science.

This handbook is designed for learners, researchers, and professionals seeking a balanced perspective on lipid resources and their applications. It promotes conceptual understanding, technical awareness, and informed utilisation of lipid-based materials in academic and applied settings.
