What is the Meaning of Lipid Metabolism?

Lipid Metabolism describes the complex biochemical pathways responsible for the synthesis, storage, transport, and catabolism of fats (triglycerides, cholesterol, phospholipids) within the human organism. Proper regulation is essential for energy homeostasis, cellular membrane integrity, and the production of steroid hormones. Dyslipidemia, a common manifestation of impaired lipid metabolism, significantly increases cardiovascular risk, often co-occurring with insulin resistance. We assess this process through detailed lipid profiling.

What is the Origin of Lipid Metabolism?

The term combines "lipos" (Greek for fat) with "metabole" (Greek for change), denoting the transformation of fatty substances. Its clinical significance grew with the understanding of atherosclerosis, linking elevated circulating lipoproteins to vascular pathology. The endocrine connection became clear when recognizing that thyroid hormones centrally regulate lipolysis and synthesis rates.

What is the Mechanism of Lipid Metabolism?

The mechanism involves lipolysis, the breakdown of stored triglycerides into free fatty acids and glycerol, often stimulated by catecholamines and growth hormone. These fatty acids are then transported to tissues like muscle for beta-oxidation to generate ATP, a process regulated by PPAR nuclear receptors. Insulin generally promotes lipogenesis (fat storage) and inhibits lipolysis when substrates are abundant. Therefore, a failure in metabolic flexibility often results in chronic, inappropriate mobilization of lipids.
