B.1 lipids Flashcards
saturated fatty acids
straight shape, linear, no = ,
pack tightly so solid at rtp
monounsaturated fatty acids
1= on hc chain, cases bend, liquid at RTP, loosely packed
on = H on diffrent sides
azeite
polyunsaturated fatty acids
2+ = so way more kinks so liwud at room temp
on = H on same sides
soy oil
trans fats
edited HC chains to have more H
rly bad for you
like margarine
how do plants use lipids
oil in seeds for energyh
how do anumals use lipids
endotherms- rely on metaboliv reaxtions for heat and need constant supply of food to do this
fats are broken down to be used for ATP to power cell processes
and triglucerdies create blubber, which keeps animals warm
in a cell membrane, the set up is
extracellular
head
tail
tail
head
intracellulaer
SETROIDS structure
HAVE 4 C RINGS as a base structyre (3 hexose, 1 pentose)
can have many diffrent functional groups
hydrpohibic so can bass througb bilayer (faster reaction)
low proportipn of O:C
serioids are
important for signalling
make collesterol which is important for strucrue in lilip bylayer and makes it more flexable
essential aminoscids
we need to eat,
need for growth, maintance and repair
non-essential amino acids
body can produce from other amino acids (break down of proteins)
dipeptide bond
o
c-n
-h
almost unlimited amount of p
peptide chains able to be made
lysozyme
enzyme, 12 aa
in tears and saliva
antimicrobial and disrups cell walls of bactiera
alpha neurotoxins
poly peptide in snake venon
regulates blood sugar levels
stimulates liver to resease stored glycose (FROM PANCREAS) to blood stream
