0.5 g of a protein was hydrolyzed into amino acids, one of which is alanine. To this 0.1 g of partially deuterated alanine was H2N-CH-(CD3)-COOH was added. After through mixing, some of the alanine was separated and purified by crystallization. The crystalline alanine contains 0.652 weight percent of D. How many grams of alanine were originally present in 5g of protein?
Correct answer is between '0.38,0.42'. Can you explain this answer?

Given:
- 0.5 g of protein was hydrolyzed into amino acids, one of which is alanine.
- 0.1 g of partially deuterated alanine (H2N-CH-(CD3)-COOH) was added.
- The crystalline alanine contains 0.652 weight percent of D.
- We need to find the amount of alanine originally present in 5 g of protein.
Approach:
1. Calculate the amount of deuterated alanine present in the crystalline alanine.
2. Determine the total amount of alanine in the crystalline form.
3. Calculate the amount of alanine in the protein sample.
4. Use the ratio of alanine in the protein sample to find the amount of alanine originally present in 5 g of protein.
Calculation:
1. Calculate the amount of deuterated alanine present in the crystalline alanine:
- The crystalline alanine contains 0.652 weight percent of D.
- Let's assume the weight of the crystalline alanine is W grams.
- The weight of deuterated alanine in the crystalline form is 0.652% of W grams.
2. Determine the total amount of alanine in the crystalline form:
- The weight of deuterated alanine in the crystalline form is 0.652% of W grams.
- The weight of non-deuterated alanine in the crystalline form is (100 - 0.652)% of W grams.
- The total weight of alanine in the crystalline form is the sum of deuterated and non-deuterated alanine.
3. Calculate the amount of alanine in the protein sample:
- We know that 0.5 g of protein was hydrolyzed, and one of the amino acids obtained was alanine.
- Let's assume the weight of alanine obtained from the hydrolysis is X grams.
4. Use the ratio of alanine in the protein sample to find the amount of alanine originally present in 5 g of protein:
- We need to find the amount of alanine originally present in 5 g of protein.
- We can set up a proportion using the ratio of alanine in the protein sample:
X grams of alanine in 0.5 g of protein = Y grams of alanine in 5 g of protein.
- Solve the proportion to find the value of Y.
Final Answer:
The amount of alanine originally present in 5 g of protein is between 0.38 g and 0.42 g, as calculated from the above steps.
- 0.5 g of protein was hydrolyzed into amino acids, one of which is alanine.
- 0.1 g of partially deuterated alanine (H2N-CH-(CD3)-COOH) was added.
- The crystalline alanine contains 0.652 weight percent of D.
- We need to find the amount of alanine originally present in 5 g of protein.
