Question:
Identify the pair of carbohydrates containing galactose as one of constituent in both of them.
Identify the pair of carbohydrates containing galactose as one of constituent in both of them.
Show Hint
Remember key sugars: Lactose has 1 galactose, Raffinose family sugars have multiple galactose units.
Updated On: Apr 26, 2026
- Sucrose and Stachyose
- Maltose and Raffinose
- Raffinose and Stachyose
- Lactose and Maltose
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Carbohydrates are composed of monosaccharide units such as glucose, fructose, and galactose. To solve this, we must know the composition of common disaccharides and oligosaccharides. Step 1: Recall compositions of given carbohydrates.
Step 2: Check each option.
Step 3: Conclusion. \[ \text{Correct pair = Raffinose and Stachyose} \]
Carbohydrates are composed of monosaccharide units such as glucose, fructose, and galactose. To solve this, we must know the composition of common disaccharides and oligosaccharides. Step 1: Recall compositions of given carbohydrates.
- Sucrose = Glucose + Fructose \(\Rightarrow\) no galactose
- Maltose = Glucose + Glucose \(\Rightarrow\) no galactose
- Lactose = Glucose + Galactose \(\Rightarrow\) contains galactose
- Raffinose = Galactose + Glucose + Fructose \(\Rightarrow\) contains galactose
- Stachyose = Galactose + Galactose + Glucose + Fructose \(\Rightarrow\) contains galactose
Step 2: Check each option.
- (A) Sucrose (no galactose) + Stachyose (has galactose) $\Rightarrow$ Incorrect
- (B) Maltose (no galactose) + Raffinose (has galactose) $\Rightarrow$ Incorrect
- (C) Raffinose + Stachyose $\Rightarrow$ both contain galactose \checkmark
- (D) Lactose (has galactose) + Maltose (no galactose) $\Rightarrow$ Incorrect
Step 3: Conclusion. \[ \text{Correct pair = Raffinose and Stachyose} \]
