Q. 16.63 - An Introduction to General, Organic, and Biological Chemistry

Question

Seeds and vegetables are often deficient in one or more essential amino acids. Using the following table, state whether each combination provides all of the essential amino acids: 

a. rice and garbanzo beans.

b. lima beans and cornmeal.

c. garbanzo beans and lima beans.

Step-by-Step Solution

Answer

(Part a) Yes, rice and garbanzo beans contain all three essential amino acids: isine, tryptophan, and methionine.

(Part b) No, lima beans contain only lysine, while corneal contains only methionine. As a result, tryptophan deficiency results from this combination.

(Part c) No, garbanzo beans contain only lysine and methionine, while lima beans contain only Lysine. As a result, tryptophan deficiency results from this combination.

Step 1: Introduction (Part a).

Standard amino acids are all those found in our bodies' proteins.

The body cannot synthesize essential amino acids, so they must be obtained through food.

Step2: Given Information (part a).

One or more essential amino acids are frequently deficient in seeds and vegetables. Discover that the combination contains all of the necessary amino acids.

Step3: Explanation (Part a).

Yes, rice and garbanzo beans contain all three essential amino acids: isine, tryptophan, and methionine.

Step4: Given Information (part b).

One or more essential amino acids are frequently deficient in seeds and vegetables. Discover that the combination contains all of the necessary amino acids.

lima beans and cornmeal. 

Step5: Explanation (Part b).

No, lima beans contain only lysine, while corneal contains only methionine. As a result, tryptophan deficiency results from this combination.

Step6: Given Information (part c).

One or more essential amino acids are frequently deficient in seeds and vegetables. Discover that the combination contains all of the necessary amino acids.

Step7: Explanation (Part c).

No, garbanzo beans contain only lysine and methionine, while lima beans contain only Lysine. As a result, tryptophan deficiency results from this combination.
