13) _______________ are triesters
formed from glycerol and three
molecules of fatty acids
14) Triacylglycerols- ______ and
_____
15) Solid fats have a relatively high
percentage of __________
_________ _______ and are
general animal origin
16) Liquid oils have a higher
percentage of _____________
fatty acids
17) In ___________ lipid, a cis
double bond places a kink in the
side chain, making it more
difficult to pack efficiently in the
solid state, leading to a lower or
higher melting point?
18) _____ are used to build cell
membranes, insulate the body
and store energy
19) High intake of saturated
traicylglycerols is linked to:
20) __________ fats stimulate
cholesterol synthesis, which can
lead to cholesterol plaques
building up inside arteries
21) Build up of cholesterol can lead
to:
22) ____________ triacyclglycerols
lower the risk of heart disease by
decreasing the level of
cholesterol in the body
13) Triacylglycerols
14) Fats and oils
15) Saturated fatty acids
16) Unsaturated fatty acids
17) Unsaturated lipids, lower melting
point *think oils
18) Fats
19) Heart disease
20) Saturated fats
21) High blood pressure, heart attck and
even stroke
22) Unsaturated

23) __________ form from omega-3
fatty acids are very helpful in
lowering the risk of a heart attack
24) If the double bond of the
unsaturated triacylglycerol is trans,
is it still beneficial?
25) _____ fat, which are primarily
synthesized instead of naturally
occurring, act like saturated fats and
increase the cholesterol levels in the
blood
26) Triacylglycerols are hydrolyzed with
water in the presence of:
27) Triacylglycerol hydrolysis forms
what:
28) Triacyglycerol-metabolism: Humans
store energy as triacylglycerols in
_______ cells below the surface of
the skin in the breast area and
surrounding internal organs
29) Number of adipose cells is
_________, weight gained or lost
causes them to _________ or
________
30) How do you metabolize
triacylglycerols for energy?
31) Complete metabolism of a
triacylglycerol yield:
23) Triglycerols
24) No the benefit is lost
25) Trans
26) Acid, base or enzyme in the body
27) Forms a carboxylic acid and
glycerol
28) Adipose cells
29) Constant; weight gained or lost
causes them to swell or shrink
30) The esters are hydrolyzed by
enzymes called lipase
31) CO2, H2O and a great deal of
energy
