Lipid metabolism involves the degradation of fatty acids, which are fundamental biological molecules and the building blocks of more structurally complex lipids. In order to be metabolized by the cell, lipids are hydrolyzed to yield free fatty acids that then converted to acetyl-CoA through the β- oxidation pathway. Because oxidation of carbohydrates also leads to an increase in acetyl-CoA levels, this regulatory event al-lows for cross talk between the catabolic pathways con-trolling lipid and glucose metabolism, and provides a mechanism for blocking lipid oxidation when cellular energy needs are low. The majority of fatty acids are incorporated into.

This happens because all of the catabolic pathways for carbohydrates, proteins, and lipids eventually connect into glycolysis and the citric acid cycle pathways (see Figure ). Metabolic pathways should be thought of as porous—that is, substances enter from other pathways, and intermediates leave for other pathways.
ω-oxidation: a minor, but clinically significant, pathway for fatty oxidation initiated by microsomal ω-hydroxylation reactions, also involves the oxidation of dicarboxylic acids generated Ketone body: any of the compounds, β-hydroxybutyrate, acetoacetate, and acetone, generated during hepatic ketogenesis from the substrate, acetyl-CoA. Lipid oxidation has detrimental effects on both food quality and human health, and efforts must be made to minimize oxidation and improve oxidative stability of lipid products. Antioxidant strategy has been successfully employed in the food industry for quality preservation of the food products and in the medicinal industry for risk reduction.

Book Description. This volume complements Lipid Oxidation Pathways, Volume 1 by focusing on the oxidation kinetics and mechanisms governing the behavior of different molecular species involved in lipid oxidation reactions. It provides a more detailed review of the reactions of other lipid molecules than conventional polyunsaturated fatty acids.
Lipid Oxidation. Lipid oxidation is a highly complex Lipid Oxidation Pathways book of free radical reactions between fatty acids and oxygen, which results in oxidative degradation of lipids, also known as rancidity.
Lipid oxidation intermediate products (free radicals) and end products (reactive aldehydes) may interact with other food constituents, such as proteins. The various chapters illustrate the special features associated with different lipids, antioxidants, reaction conditions, and lipids environments.
The material in this book provides a better understanding of lipid oxidation by: This volume complements Lipid Oxidation Pathways, Volume 1 by focusing on the oxidation kinetics and mechanisms governing the behavior of different molecular species involved in lipid oxidation reactions.
It provides a more detailed review of the reactions of other lipid molecules than conventional polyunsaturated fatty acids.
Lipid oxidation presents several distinctive challenges for analysis: (1) providing quantitative, reproducible analyses that accurately reflect oxidation chemistry; (2) tracking multiple pathways to avoid missing oxidation and to gain a more complete picture of the full extent and effects of oxidation; (3) obtaining maximum detailed information.

Covering the diverse topics that contribute to research in this important field, this book explores: The mechanisms of lipid oxidation, both enzymatic and non-enzymatic.
Lipid metabolism entails the oxidation of fatty acids to either generate energy or synthesize new lipids from smaller constituent molecules. Lipid metabolism is associated with carbohydrate metabolism, as products of glucose (such as acetyl CoA) can be converted into lipids.
Figure Triglyceride Broken Down into a Monoglyceride. Oxidation of Lipids in Foods. L ipids are triacylglycerol and formed when three fatty acids esterifies with a molecule of alcohol or glycerol (Ubhayasekera, ).Unsaturated fatty acids mainly consist of omega-9, omega-6 and omega-3 series are highly susceptible to oxidation (Galano et al., ).Rate of oxidation depends on degree of unsaturation and increases with increase in double bond of.
Overview of lipid catabolism pathway during fasting. Nutrient deprivation is one of the harshest conditions that an organism may face. To sustain cellular metabolism, lipids, proteins, and carbohydrates must be degraded to give rise to fatty acids (FA), amino acids (AA), and pyruvate, respectively (see Glossary).These substrates can in turn generate ATP to sustain energy.

Systematic studies of these alternate competing pathways will a) measure radicals, volatile and non-volatile products in oxidizing methyl linoleate as a model lipid to establish clearly which alternate pathways are active and how they change the dynamics of lipid oxidation, b) determine whether alternate pathways occur simultaneously with.
The long-chain acyl-CoA can then enter the fatty acid β-oxidation pathway, resulting in the production of one acetyl-CoA from each cycle of β-oxidation.
This acetyl-CoA then enters the TCA cycle. The NADH and FADH2 produced by both β-oxidation and the TCA cycle are. Author by: Edwin N.

The hypothetical alternative pathways outlined above illustrate the potential competition for various isomeric pentadienyl and peroxyeicosatetraenoyl radical intermediates that may be crucial for a thorough understanding of factors influencing the generation and evolution of the end products of free radical-induced lipid oxidation.
Microalgae were originally considered as sources of long-chain polyunsaturated fatty acids (PUFAs), mainly for aquaculture purposes.
However, based on the fact that their fatty acids (FA), stored as triacylglycerides (TAG), can be converted into biodiesel via a transesterification reaction, several microalgal species have emerged over the last decade as promising feedstocks for biofuel .Lipid metabolism begins in the intestine where ingested triglycerides are broken down into smaller chain fatty acids and subsequently into monoglyceride molecules (see Figure b) by pancreatic lipases, enzymes that break down fats after they are emulsified by bile food reaches the small intestine in the form of chyme, a digestive hormone called cholecystokinin (CCK) is released.However, lipid oxidation is a circular reaction because when non-radical species are created, it will easily combine with another free radical to go back to the oxidation cycle, which can result in a continuous degradation of lipid.
Measurement of lipid oxidation. Numerous analytical methods are conducted to measure the lipid oxidation in food.
