glycerol
Pancreatic
lipase
Glycerol(transported
to liver)
TG (carried by a
type of Apo protein
to form
chylomicrons)
The

ADIPOSE
CELL
Bile salt and colipase is used to
facilitate fatty acid and
glycerol’s absorption

and also in VLDL)
THE BLOOD STREAM
Fatty acid

TG ( most of lipid
stored in adipose
tissues as TG)
ADIPOSE CELL
NOTES
# TG=triacylglycerol
# to release lipid
from the adipose
cells to the blood
stream , TG must be
converted again to
fatty acid and
glycerol
#fatty acids that
carried by albumin
are released from
adipose tissueBY:HUSSEIN ALI HUSSEIN
