nutrient digestion and absorption 2 Flashcards
how are di and tri peptide moved into the cell
through pept1 transporters
what is need for di an tro peptie to move into the celll
h+ with them, which then leave again
how anre mone pepoes absone
broken down into invicul anoacids using peptiase
what trapsoreed move na in in exchange fo protein for di / tri pmerntidie adding
nhE3 transporter
what is the benfitis of di/ tri peptide absobption
it makes the area clsoe to the intereisla cell lumen more acidic thus decreasing the ph making it more freily enfvirement for fats
what percent of preotien in teh small intestis are di perpoesa nd tri prepis
50
what do di and trip peptoes get hydolied into amnio acids as
ingtercelluar pididase
what is the lacteal
a capilly like lymphatic vell connected to the lymph below
what are the layers of a villus from exterior to interio
epithel, lamina propila, blood capillaries, lacteal
where are fats stored
white adipose tissue
what are fats stored as
triglycerides
why are fats so energy dense
the lack oxygen
what are triclyges made up of
gylcer and 3 fatty acids joined togher by a ester bond
what is relased when fat is broked up
water
what enzyme digests fa
pancreatic lipase
are triacyclgoes soluble in water
no
how does lipase work
seperates triglyceries into molyges and free fatty acids , making them slumeb in water
surfactant role
outside water solube (hydorpllic head) inside water hating oil lovig ( hydropbobic tail
hgow are fat globeas abroed
taken into a water solue bmisxtre by bile salt and phosohes to make an emilued fat drop;les
are bil salts hydrophobic or hydroilic
both
