Question

for adults, the rda of the amino acid lysine is 12 mg per kg of body weight. how many grams per day should a 79 kg adult receive? express your answer in grams per day.

Explanation:

Step1: Calculate total mg of lysine

Multiply RDA (12 mg/kg) by body weight (79 kg).
$12\ \text{mg/kg} \times 79\ \text{kg} = 948\ \text{mg}$

Step2: Convert mg to grams

Since $1\ \text{g} = 1000\ \text{mg}$, divide by 1000.
$\frac{948\ \text{mg}}{1000\ \text{mg/g}} = 0.948\ \text{g}$

Answer:

0.948
