Real questions that test this

खालीलपैकी कोणता पिष्टमय पदार्थ डायसॅकराइड आहे ? Which of the following carbohydrates is a disaccharide ?

1)Glucose
2)Fructose
3)Sucrose✓ Correct
4)Cellulose

Sucrose is a disaccharide formed by the combination of two monosaccharides, glucose and fructose. Glucose and fructose are monosaccharides, while cellulose is a polysaccharide.

सुक्रोज चे पाण्याबरोबर संयोग होऊन पृथःक्करण झाल्यास समप्रमाणात कुठले मिश्रण तयार होते ? / Upon hydrolysis, sucrose yields equimolar mixture of :

1)ग्लुकोज आणि रीबोज / Glucose and ribose
2)फ्रुक्टोज आणि रीबोज / Fructose and ribose
3)ग्लुकोज आणि फ्रक्टोज / Glucose and fructose✓ Correct
4)लॅक्टोज आणि माल्टोज / Lactose and maltose

Hydrolysis of sucrose (a disaccharide) breaks it down into an equimolar mixture of glucose and fructose.

योग्य जोड्या लावा : अ. मोनोसॅकराइड ब. डायसॅकराइड क. ट्रायसॅकराइड ड. पॉलीसॅकराइड Match the correct pairs : A. Monosaccharide B. Disaccharide C. Trisaccharide D. Polysaccharide

(a)i. रॅफिनोज ii. स्टार्च iii. ग्लुकोज iv. सुक्रोज

1)अ - iii ब - ii क - i ड - iv
2)अ - ii ब - i क - iii ड - iv
3)अ - iv ब - iii क - ii ड - i
4)अ - iii ब - iv क - i ड - ii✓ Correct

Monosaccharide matches with Glucose (iii), Disaccharide matches with Sucrose (iv), Trisaccharide matches with Raffinose (i), and Polysaccharide matches with Starch (ii).
