Lipoproteins

#14
Front (Question)

5 TYPES Lipoproteins

Back (Answer)

• Chylomicrons • Very Low Density Lipoprotein • Intermediate Density Lipoprotein • Low Density Lipoprotein • High Density Lipoprotein

#15
Front (Question)

ƒ Most dense to the least (based on density):

Back (Answer)

HDL > LDL > VLDL > Chylomicron

#16
Front (Question)

function: transport TAG absorbed from the intestine to adipose, cardiac & skeletal muscle

Back (Answer)

Chylomicron

#17

Back (Answer)

Very Low Density Lipoprotein (VLDL)

#22
