Preface
Fats and oils are a large group of chemical structures different in shape, size and
physicochemical characteristics, collectively identified as lipids. Ancestrally, lipids
were fundamental components in the early human diet, providing an important and
valuable amount of energy (9 kcal / g 37.7 kJ / g) and other components, such as
essential fatty acids, fat soluble vitamins and sterols (such as cholesterol and/or
phytosterols). The different structural characteristics of lipids give them multiple
biochemical, physiological and nutritional functions, being transcendental to our body
and allowing, among other functions, the development and growth of highly
specialized tissues, such as the brain.
Lipids have been important in the evolution of many species and especially for the
human being. At present a significant number of studies have demonstrated the role of
lipids in the development, prevention and / or treatment of various acute and chronic
diseases. The present book, "Lipid Metabolism", discuss in its various chapters the
importance of lipid metabolism in humans and other species.
The first section of the book is dedicated to the structure and general metabolism of
lipids, with emphasis on the structural and metabolic differences of each lipid.
Regarding lipid metabolism, the main features from their absorption and digestion are
also discussed, highlighting in particular the complexity of lipoprotein metabolism.
At molecular level lipid metabolism is even more complex. Some chapters revise and
discuss the close relationship between some lipids and i) the cell membrane structure
ii) the regulation of intracellular signaling pathways, iii) the direct interaction with
gene transcription factors iv) the regulation of gene expression, and v) the effect of
lipid peroxidation in cellular metabolism. All these interactions involving lipid
metabolic products show the relevance of these molecules in the maintenance of
normal structural, organic and systemic cellular activity.
Currently, a central element in the study of lipid metabolism is the participation of
these molecules in the development and the prevention of certain diseases, especially
those of chronic non communicable nature such as, obesity, insulin resistance, diabetes
mellitus, atherosclerosis, cardiovascular disease and cancer. It is well known the
association of some saturated fatty acids, such as palmitic acid (C16: 0) or of
X Preface
cholesterol, with the increased risk of cardiovascular diseases, or the effect of the
imbalance of omega-6 and omega-3 fatty acids in the course of inflammatory process
and its posterior resolution.
An interesting aspect of lipid metabolism refers to its importance in plants where, such
as in animals, lipids represent more than an energy reservoir, highlighting as
regulatory elements in the metabolism and in the functional properties of many
vegetables, and having a direct impact on the health and nutrition of the human and
animal population.
Collectively, the book intent to be a systematic and comprehensive review of lipid
structure and metabolism. Special emphasis is made to the functional characteristics of
some lipids, such as membrane phospholipids. Some chapters discuss the molecular
aspects of lipid metabolism, its interaction with oxidative stress, and particularly the
close relationship of some lipids with health and disease.
