Biochemistry WGU c785 Exam
Questions and Answers
Nonenzymatic glycosylation or glycation creates glycoproteins by:
1. Chemical addition of sugars to polypeptides
2. Extracellular synthesis
3. Attaching 20 amino acids
4. Secretion into extracellular matrix - Answer-1
Nonenzymatic glycosylation or glycation creates glycoproteins by the chemical addition of sugars to
polypeptides. Since this type of glycosylation is nonenzymatic, the time and the concentration of sugar
control glycosylation. Because people with higher circulating levels of glucose have higher levels of
nonenzymatic glycosylation, measurement of the glycosylated hemoglobin A1c is a diagnostic test used
to monitor blood sugar levels in persons with diabetes.
Which of the following is a 5-carbon sugar?
1. Glucose
2. Fructose
3. Ribose
4. Sucrose - Answer-3
