essential aa
arginine cystein glutamine glycine proline tyrosine
conditionally essential aa
eg of complete proteins; foods that contain all essential aa
meat/fish
dairy
soy
quinoa
incomplete proteins, and which aa they are missing
corn/tryptophan, lysine
wheat, rice/lysine
legumes/methionine
protein RDA for a sedentary vs active person
.8 g/kg
.8-1 g/kg
- if a pt is RESISTANCE training, they should consume ___ g/kg protein
- ___ g of good quality prot
1.5-1.7 g/kg
20g
- if a pt is ENDURANCE exercising, they should consume ___ g/kg protein
- 20g good qual prot w/i 30 min and every __h for a total of __ h
1.2-1.4 g/kg
4h/12h
protein AMDR
10-35% energy
four things that eval for protein quality
nitrogen balance
PDCAAS
PER
BV
- what is used to determine quality with nitrogen balance of protein
- done in hospitalized pts
intake vs excretion
PDCAAS (protein digestibility corrected amino acid score) assesses digestibility in foods for:
1-4yo
PER (protein efficiency ratio) calcuation
gain in body weight (g) / g of protein consumed
PER weight gain/g is used for protein qual in
infant formula/food (
BV (biological value) measures protein quality by:
N retained vs excreted
-N free diet -> test protein, compare excrement N
protein functions in transport, enzymes, structure, Ig, intracellular ____, cell ____ and ___ balance
buffering
signaling
fluid
protein function fluid balance recommendation
1-1.5 mL/kcal consumed
protein-energy malnutrition, which presents with skin/bone appearance, depressed metabl, stunted brain dev, weak IS
marasmus
protein malnutrition presenting with stomach distention, retarded growth, fatty liver, loss of appetite
kwashiorkor
PKU, sickle cell anemia and cystic fibrosis are all ___ ____, related to protein
genetic abnormalities
