The peptide bond is formed between which functional groups?
Which sugar is present in RNA?
What type of isomerism does glucose exhibit?
Sample Questions
Identify the reducing sugars from the following options:
Show answer
Glucose, Fructose, Maltose
Reducing sugars contain free anomeric carbon that can reduce Benedict's or Fehling's reagent. Glucose, fructose, and maltose are reducing sugars, while sucrose is non-reducing as both anomeric carbons are involved in glycosidic linkage.
Identify the purine bases from the following:
Show answer
Adenine, Guanine
Purine bases have double ring structure. Adenine and Guanine are purines. Cytosine, Thymine, and Uracil are pyrimidines with single ring structure.
Which amino acid does not have a chiral carbon?
Show answer
Glycine
Glycine has the structure NH₂-CH₂-COOH where the α-carbon has two hydrogen atoms, making it achiral. All other amino acids have chiral α-carbons.
The hydrolysis of sucrose gives:
Show answer
Glucose + Fructose
Sucrose on hydrolysis with dilute acid or invertase enzyme gives equimolar mixture of D-glucose and D-fructose. This process is called inversion of sucrose.
