lecture 10: Lipid classifications, fatty acids, lipases, fat oxidation Flashcards
what is the difference between omega 3 and omega 6 fatty acids
omega three has the first double bond on the 3rd carbin from the methyl end
omega six has the first double bond on the 6th carbin from the methyl end
how do you differenciatied saturated, monounast, polyunstatu
look at the presence og double bonds
H3C is the methyl or carboxyl end
methyl
COH is the carboxyl or methyl end
carboxyl
what is another name for the carboxyl end
alhpa end
what is another name for the metyl end
omega
true or false: omega 3 has postive effects pm cardiovascular but omega 6 has negatvie effects
false they both has postitve effetcs
what is an important omega 3 that is consumed the most
EPA
what is the chemical formula for EPA and the name
eicosapentanoic
C20:5: n-3
what is the chemical formula for DHA and the name
docosahexanoic
C22: 6n-3
what is the chemical formula for alpha linealic acid
ALA
C18: 3n-3
what are 2 imporatnt omega 6 and their formulas
AA/ARA: arachadonic acid C20:4n-6
LA: linoleic acid C18: 2n-6
which omega 3 has 5 double bonds
EPA
which omega 3 has 6 double bonds
DHAA
which omega 3 has 3 double bondd
ALA
whcih omega 6 has 4 double bonds
aracadonic
which omega 6 has 2 doubl bonds
linoleic acid
omega 3 and 6 have benefits on hormone regulation
false
on CV benefits
what does PUFA
poly unsaturated fatty acids
which types of fatty acids have the most healthy benefits
omega 3 polyunsaturated fatty acids
what are the CV in terms of vascular structure
decrease atherogenesis
decrease arterial stiffniss
decrease vascular smooth muscle cells
maintain intima media thickness
what is atherogenesis
build up of plaque (from fatty acids, chrolesterol) which causes the derodation of inner lining and can block blood flow
what is arterior stiff mness
with CV problems, the arterior walls can become hardened which impedes blood flow
is having more or less vascular smooth cells better
having less
what are the benefits in vascular function from omega 3
decrease in endothelial disfunction (releases nitrous oxide)
decrease in oxidative stress (most likely due to helping antioxidants)
decreae in inflammation
what is another name for a triglyceride
triacylglyceride
have many crbons are in the glycerol
3 carbon
glycerol serves as teh BLANK for tris
as the backbonw
what is a trigluceride
glycerol backbone with 3 fatty acids joinnng by ester bonds/linkages
true or false: the fatty acids that compose the tri have no effect on the properties of it
false
true or false: you can have different types of fatty acids making up the 3 fatty acids
true
fats have FA with more of less double bonds
fewer
oilds have FA with more or less double bonds
more
oils are saturated or unsaturated
unsaturated
fats are saturate or unsaturated
saturated
what is the function of the glycerold
allows the different fatty acid tails to attach
how is the tryglycerid formed
the glycerol binds with the 3 fatty acids (carbon attaches the the oxygen) by forming 3 water molecules and 3 ester linkages
what types of bonds are important in formation of tris
ester bonds
