What lipids are stored in adipose tissue
Triglycerides-esters of fatty acids and glycerol
Triglycerides are typically
Esters of fatty acids and glycerol
In what form are triglycerides brought to the cells
form of chylomicron triglycerides
How is fatty acids brought to the cells?
In the form of chylomicron triglycerides. triglycerides synthesizes in the liver and brought to tissue in form of very low densely lipoprotein. (VLDL) and by synthesis of free fatty acids and glycerol from glucose to form triglyceride in adipose cells
What are chylomicron
Particles found in intestinal epithelial cells. they are transported in blood and plasma in mesenteric lymph
What are chylomicron made of
Central core, triglycerides, cholesterol esters surrounded by stabilizing monolayer consisting of apoliproteins, cholesterol phospherous
What 2 organelles participates in the process of lipid uptake and storage
Mitochondria and smooth ER
When does the accumulation of insulin occur?
When adipose cells synthesize fatty acids from glucose
What stimulates uptake of glucose into adipose cells and increases synthesis of lipoprotein lipase
Insulin
What factors have roles in metabolism of adipose tissue
Growth hormones glucocorticoids, prolactin,corticotropin, insulinand thyroids
What tissue also functions as a secretory organ?
Adipose tissue
Triglyceride lipase ia an enzyme known as what?
Hormone sensitive lipase
What are the functions of adipose tissue?
Secretory organ synthesize molecules carried by blood or remain attached to endothelium of capillaries areound adipose tissue
What is the most extensively studied substance produced by adipose cells
Leptin
What is leptin?
Protein made by 164 amino acids
