Triacylglycerol is transported in the blood by very low- Break it

by chylomicron that was absorbed and created in the small
intestine. enzyme

Endothelial cells, which line blood vessels, have an enzyme called
lipoprotein lipase on their surfaces. When triacylglycerol is trans-
ported through the capillaries in adipose tissue, muscles, and
other tissues, it encounters lipoprotein lipase and is hydrolyzed
into fatty acids and glycerol.

Those fatty acids and glycerol are captured in adipose tissue.

The captured fatty acids and glycerol are recombined and stored
in triacylglycerol.

Ooh And when this happens,
fat steadily increases!
