Question
VITAMINS : NUTRITION CALCULATIONSFOR EACH OF THESE VITAMINS, WRITE THE UNIT OF MEASURE:
Thiamin: folate: riboflavin:1.1-1.3 mg/day
Niacin: 14-16mg vitaminB12 vitamin C:90 mg/day
vitamin B6 :
How much higher than 2 milligrams is 2 grams?
Vitamin B12 is measured in micrograms. How many micrograms are in a gram? How many grams are in a teaspoon of a granular powder? How many micrograms does that represent? What is your RDA for vitamin B12?
Based on the information provided below, calculate how much niacin a woman receives from a diet that delivers 90 grams protein and 9 milligrams niacin. (Assume her RDA for protein is 46 grams/day).
Most dietary proteins contain about 1 percent of tryptophan. To determine the amount of tryptophan in protein, divide grams of protein by 100.
Multiple by 1000 to convert grams of tryptophan to milligrams.
60 milligrams of tryptophan = 1 mg of Niacin. = 1 NE
Is this woman getting her RDA of niacin (14 milligrams NE).
Explanation / Answer
Vitamin B12 is measured in micrograms. How many micrograms are in a gram? How many grams are in a teaspoon of a granular powder? How many micrograms does that represent? What is your RDA for vitamin B12?
1 gram = 1000mg
1 mg = 1000 mu grams (1000 x 1000 )
teaspoon of a granular powder = 5grmans
= 5 x 1000 x 1000 = 5,000,000 mu gram/teaspoon
