Why fructose is called Levulose?
Fructose, also called fruit sugar, is the only naturally occurring ketohexose . It is also referred to as levulose because it has an optical rotation that is strongly levorotatory. Fructose is a simple ketonic monosaccharide.
What does fructose do for the body?
Fructose functions in the body Fructose is digested in the liver to produce mainly glucose (~50%), and minor amounts of glycogen (>17%), lactate (~25%) and a small amount fatty acids. Glucose travels through the bloodstream to all organs and muscles, where it is transformed into energy.
Is fructose a ketohexose?
Fructose is a ketohexose found in honey and a wide variety of fruits and vegetables. Combined with glucose in an α(1→2)β linkage, it forms sucrose (Chapter 9).
What is the difference between fructose and levulose?
As nouns the difference between levulose and fructose is that levulose is (carbohydrate) d-fructose, the left-rotating stereoisomer of fructose while fructose is (carbohydrate) a monosaccharide ketose sugar, formula c6h12o6.
What is dextrose and levulose?
As nouns the difference between levulose and dextrose is that levulose is (carbohydrate) d-fructose, the left-rotating stereoisomer of fructose while dextrose is the naturally-occurring dextrorotatory form of glucose monosaccharide molecule.
Does fructose cause liver damage?
When large quantities of fructose reach the liver, the liver uses excess fructose to create fat, a process called lipogenesis. Eventually, people who consume too much fructose can develop nonalcoholic fatty liver disease, a condition in which too much fat is stored in the liver cells.
Does fructose cause inflammation?
Also, researchers have noted that fructose causes inflammation within the endothelial cells that line your blood vessels, which is a risk factor for heart disease ( 16 ). High fructose intake has likewise been shown to increase several inflammatory markers in mice and humans ( 10 , 17 , 18 , 13 , 19 , 20 ).
What is aldohexose and ketohexose?
Aldohexoses and ketohexoses are two subclasses of hexoses. A hexose is a monosaccharide compound containing six carbon atoms. The key difference between aldohexose and ketohexose is that aldohexoses contain a formyl group whereas ketohexoses contain a ketone group.
What are the 4 ketohexoses?
Ketohexoses have three chiral centers. As such, there are eight possible stereoisomers. Examples of ketohexoses are fructose, piscose, sorbose, and tagatose.
Can diabetics take fructose?
Unlike glucose, fructose causes a low rise in blood sugar levels. Therefore, some health professionals recommend fructose as a “safe” sweetener for people with type 2 diabetes ( 3 ).
