Carbohydrates:

what is the difference in monosacchrides, disaccharides, and polysacchrides?

What are the structures of glucose, frustose, sucrose, lactose, and starch, such that you could predict their responses in the following tests:

Benedicts test (remains bright blue if negative for a reducing sugar, turns any other color if positive for reducing sugar. Tests for free or potentially free aldehyde or ketone groups)

Seliwanoff’s Test (turns red or pink, speed of color change indicates ketose vs. aldose, and monosacchride vs. disaccharide)

Iodine Test – tests for polysaccharides, turns blue-black in starch, red-to-brown color in other polysaccharides

Carbohydrates are the main sources of fuel for the body. They’re broken down into glucose, which is “burned” as fuel for the body. i. What is expected to occur when the body’s supply of glucose runs out? ii. Would insulin or glucagon be of any importance in this regard? Explain your answer. iii. As a nurse on duty, a patient is brought to the emergency ward with symptoms of weakness, dizziness, headache and slight disorientation. The patient has a history...

What is the difference between how a person with normal glucose levels performs on the OGTT...

What is the difference between how a person with normal glucose levels performs on the OGTT compared to a person with prediabetes or diabetes? Patients with prediabetes are very sensitive to the effects of insulin, so plasma glucose levels remain elevated at two hours. The glucose levels in patients with prediabetes and diabetes continue to rise for an hour after the glucose is consumed and remain elevated at two hours. Patients with diabetes absorb more of the glucose drink from...

Yeast cells need to convert all sugars to glucose before they can perform glycolysis. Some carbohydrates need to be prepared in longer metabolic pathways than others. Write a prediction about the efficiency of respiration for each of the three food sources given the properties listed below. (Note: an equal mass of sugar was used in each case) Glucose, Sucrose, Maltose Glucose is ready for glycolysis. Maltose is a disaccharide made from two glucose monomers. The glycosidic bond between the monosaccharides...
