very low density lipoprotein (VLDL)

Function: - VLDL matures in the periphery, eventually forming LDL - some VLDL may be removed via VLDL receptors - Apo C2 present in VLDL stimulates activation of lipoprotein lipase - Apo C exchanges with HDL in the maturation process Expression: - VLDL is synthesized & released by the liver with synthesis closely related to energy availability, without regard to calorie source
