lecture 25 Flashcards
two main types of lipids
storage lipids and membrane lipids
how many fatty acids does glycerol have
3
2 components of a fatty acid
carbonyl group, fatty acid hydrocarbon chain
cis means what
kink in chain
delta = what
of carbonyl group, includes all double bonds
omega = what
from end opposite carbonyl group, includes only first double bond
two essential fatty acids
linoleum acid and alpha lenolinic acid
kink means what
unsaturated
12:0
lauric acid
14:0
myristic acid
16:0
palmitic acid
18:0
stearic acid
16:1 (delta 9)
palmitoleic acid
18:1 (delta 9)
oleic acid
18:2 (delta 9,12)
linoleic acid
18:3 (delta 9, 12, 15)
alpha linoleic acid
20:4 (delta 5,8,11,14)
arachidonic acid
Lauric acid
12:0
myristic acid
14:0
palmitic acid
16:0
stearic acid
18:0
palmitoleic acid
16:1 (delta 9)
oleic acid
18:1 (delta 9)
linoleic acid
18:2 (delta 9,12)
alpha linoleic acid
18:3 (delta 9,12,15)
arachidonic acid
20:4 (delta 5,8,11,14)
lower melting point means what
more unsaturation
shorter chain is more or less soluble
less
most effective way to store energy
triacylglycerols
a glycerol with 3 substituant chain coming off
triacylglycerols
found in cell membrane , contains hydrophilic and phobic parts
glycerolphospholipids
glycerol with a saturated fatty acid and an unsaturated fatty acid coming off
glycerolphospholipids
nitrogen containing, also found in cell membrane
shingolipds
sphingosine with fatty acid
shingolipid
can be cleaved and used in in intracellular signaling
phosphatidylinositol
type of lipid derived from fatty acid
eicozanoids
has 4 rings
cholesterol
is cholesterol hydrophobic or Phil
phobic
cholesterol function
synthesize sex hormones, regulate blood pressure
do we consume cholesterol or is it synthesized
it is synthesized
involved in cell syn and vision
vitamin A
derived from cholesterol, deals with calcium deposition in to bones
vitamin D
deficiency in this result in rickets
vitamin D
aldehyde and alcohol forms
vitamin A
antioxidant in cell membrane
vitamin E
involved in blood clotting
vitamin K
synthesized by microbes
vitamin K
