Chemistry Question on Organic Chemistry- Some Basic Principles and Techniques
Carrier ions like sodium ions facilitate the absorption of substances like:
A
(A) Amino acids and glucose
B
(B) Glucose and fatty acids
C
(C) Fatty acids and glycerol
D
(D) Fructose and some amino acids
Answer
(A) Amino acids and glucose
Explanation
Solution
Explanation:
Carrier ions like sodium ions facilitate the absorption of substances like amino acids and glucose.Glucose and amino acids are co-transported along with sodium ions in the intestinal epithelium. The Na/Glucose co-transporter (SGLT 1) facilitates glucose-coupled sodium absorption while amino acid-coupled sodium absorption occurs through the epithelial cells with the help of sodium/amino acid co-transporters. There are specific co-transporters for different classes of amino acids.Hence, the correct option is (A).
