An example of a positive Seliwanoff’s test. Seliwanoff’s test is a chemical test which distinguishes between aldose and ketose sugars. If the sugar contains a ketone group, it is a ketose. If a sugar contains an aldehyde group, it is an aldose. This test relies on the principle that, when heated, ketoses are more rapidly dehydrated than ...
Ketoses and aldoses can be chemically differentiated through Seliwanoff's test, where the sample is heated with acid and resorcinol. [4] The test relies on the dehydration reaction which occurs more quickly in ketoses, so that while aldoses react slowly, producing a light pink color, ketoses react more quickly and strongly to produce a dark red color.

Ketosis is a metabolic state characterized by elevated levels of ketone bodies in the blood or urine. Physiological ketosis is a normal response to low glucose availability. . In physiological ketosis, ketones in the blood are elevated above baseline levels, but the body's acid–base homeostasis is maintain
Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of diabetes mellitus. [1] Signs and symptoms may include vomiting, abdominal pain, deep gasping breathing, increased urination, weakness, confusion and occasionally loss of consciousness. [1]
Kelly Ripa and Mark Consuelos are mourning the loss of their beloved dog, Chewie, who died on Tuesday, Feb. 4, at the age of 17.. The couple opened up Wednesday's episode of Live with Kelly and ...
Ketotic hypoglycemia refers to any circumstance in which low blood glucose is accompanied by ketosis, the presence of ketone bodies (such as beta-hydroxybutyrate) in the blood or urine. This state can be either physiologic or pathologic; physiologic ketotic hypoglycemia is a common cause of hypoglycemia in children, often in response to ...
In our guide to building a skin care routine in your 60s, experts told us that aging skin becomes dry and dehydrated. That's why we like that the ELEMIS Pro-Collagen Marine Cream is chock full of ...
