chapter 7 Flashcards
proteins
organic moelcuels folded chain of aminaocids , enrgy yielding nurtirne growth andrepait tissue sna dmuscles
prtoein structire
aminacids main ocmponetn long chain , nitrogen conating aminegroup , carboxlic acids , r side chain 21 minoacids differ by r chains
esential amino acids
9 aminoacids required for the body cant make mitself ;like lleuice isolucie histidne
non essential
also have critical role in body , modyifiyin other mainoacids , alanine , serine
complete protein
9 essetnial aminocaids , aimals prodcut better than plants plans are icplomete esential missing are liitigm aminoacids , plants that have compelte are soy quinocva balckweta
conditonaly esesntial
six , arginince , tyrosine , body not able to synthesis adequte amounts
complemting mutural complemting
ric eincomete bean incomplete together compelmting
protein synthesis ,
rn drna sequnece pair , transmiantion , diet lacks non esential liver can make it through transmaintaion , lmiting aminaocids compromise protein synthesis
protein bond
proteins are polypeptide chian peptide bond ainacids ajactn bonds , hwo the protien fold form scondry teritay quantery structure primary is criticcal protien role i n body
secondy
beta and alp ahelix h bond
teritary
folding , salt and siulfide bridges , fully function protein
denautrion
acid , agitation , heat , loss function , cook food ,s tomach acids , enzymes wok on priamry strucrutes eprate amiocacs , unraveled
quantery
they come together eight or less protein subunits
protei digestion
begins in teth mechanical , no digestiving enzyem in mouth , stomach lume hcl pepsin , break bonds m small intesoen pancreating trypsin chrymtrypsin m acive transport villi , acid villus ,
protein fucntion
bone , skin , muscle collagen for bone , elastin fro structual supoort
transport
hemoglobin transport oxyge [rpeom ,
enzymes
spped up chemical reactions
movemnt
myon actin , mysoin proetinbudn to actin adn shorten muscle lennght
fluid balance
aminaocids ounf in bloo fproteins carry psotove and negative charge water i attafcted to blood due to draw proteins m water dosen tbui up in extracellur risk edema
protein or isease protection
bacteria infecio viruses , at as barrie , antibodies y shaped stick t pathogens
synthesi snn protein substaces
creaitne dna rna , neuransmiter dompaime serotonn
energy
energy yieling its not its main function 5-10 eergy . watfil t reve nitrgoen groip
protien and helath
protein deficeny leads o diaseas maramus waste syndrome maangind body temp and anemia chidren infants and kwashrikor , malnutrion protein m wast size low protei norn amze , sollen legs
protein and body weight calori intake above ened , protein rich foos more illing , protein energy ablance , metablosim lipidds an carb aminoacids play huge role
protein and musle growth
grwoth repair and tissues ,
protein and kiney helath
low protein diets recomended
bone health
collagen , calcium exertion m icnrease boen density protein
protein quality
two factprs , hwo well protein is igested and how the types o aminoacids matcch body requirment
pdcaas
protein digestibly corrected ajinoacids ascore . scorea chive 1.0 total amount protein in foods ,
diaas
digestible indispenable aminoacids score . digested om illiu, abspbred aminoacids by bpdy bette for protein uqlaity
protein suplmenets
increase msucle sternght and size expensive busy life , certian amount mroe than that dosent gai any more , low i nfibre low in pytochemicals ,
bracnhed aminoacids
esentila aminoacids bracnhed side chamns , bcaa meabtlozied muscle instead of liver , recovery bet bcaa sal,on yougure chiken
animal vs plant source protien
animal have higher pdcaas , complete protein source eseential aminoacis , vitamin d iron b12 , iron zinc omega 3 fatty acids sat fat and absen in fibre higher risk , animals more lan mroe water methan gas
