Quiz 2-PCDAA calculation Flashcards
1
Q
what is the protien digestibility corrected amino acid score (PDCAAS) equation
A
PDCASS=true fecal protien digestability x (mg of first limiting amino acid in 1 g of test protien/ mg of same AA in 1 g of reference protien)
→ PDCASS= amino acid score x digestability
2
Q
What is the amino acid scoring equation?
A
ASS= amount of essential AA (mg/1 g protien)/ mg of essential AA in 1g of ideal protien x 100%
3
Q
what are the steps of using the PDCAAs equation
A
- calculate % protien for each ingredient. To do this divide ingredient protien content by total protien
- Multiply protien percentage by digestability factor and whatever number it is that means only that will be digested
- to get the total digestability from ingredients, add
- add up each essential amino acid to see the total of that amino acid
- now divide that number by the total protien to get g per 1 gram
- multiply by 1000 to get 1 mg/ g
- calculate amino acid score: divide amino acid by amino acid content in reference protien
- finally multiply the limiting amino acid score by the total ingredient digesability found
