A lipid profile or lipid panel is a panel of blood tests used to find abnormalities in blood lipid ( such as cholesterol and triglycerides) concentrations. [not verified in body] The results of this test can identify certain genetic diseases and can determine approximate risks for cardiovascular disease, certain forms of pancreatitis, and other diseases.
Very-low-density lipoprotein size is variable, with diameters ranging from approximately 35 to 70 nm. [4] Some researchers further classify VLDL particles into VLDL1 and VLDL2 based on size (as measured by Svedberg flotation units), where VLDL1 particles are larger and contain more triglycerides, while other researchers create a tripartite system by subdividing VLDL1 into larger VLDL1 and ...
Example of an unsaturated fat triglyceride (C 55 H 98 O 6).Left part: glycerol; right part, from top to bottom: palmitic acid, oleic acid, alpha-linolenic acid. A triglyceride (from tri-and glyceride; also TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids. [1]
Lipolysis / l ɪ ˈ p ɒ l ɪ s ɪ s / is the metabolic pathway through which lipid triglycerides are hydrolyzed into a glycerol and free fatty acids. It is used to mobilize stored energy during fasting or exercise , and usually occurs in fat adipocytes .
Triglycerides, as major components of very-low-density lipoprotein (VLDL) and chylomicrons, play an important role in metabolism as energy sources and transporters of dietary fat. They contain more than twice as much energy (approximately 9 kcal/g or 38 kJ /g) as carbohydrates (approximately 4 kcal/g or 17 kJ/g).
Triglycerides are synthesized by esterification of fatty acids to glycerol. [1] Fatty acid esterification takes place in the endoplasmic reticulum of cells by metabolic pathways in which acyl groups in fatty acyl-CoAs are transferred to the hydroxyl groups of glycerol-3-phosphate and diacylglycerol.

Chylomicron structure ApoA, ApoB, ApoC, ApoE (apolipoproteins); T (triacylglycerol); C (cholesterol); green (phospholipids). Chylomicrons transport lipids absorbed from the intestine to adipose, cardiac, and skeletal muscle tissue, where their triglyceride components are hydrolyzed by the activity of the lipoprotein lipase, allowing the released free fatty acids to be absorbed by the tissues.
