Probably because it links to more receptores. Otherwise it's just your expectation.
Sucrose is a larger molecule made up of two sugars glucose and fructose. These two are about half the size of sucrose.
Sucrose is a disaccharide composed of glucose and fructose. A sucrase will hydrolyze sucrose into both constitute parts. You will be left with glucose and fructose, but you cannot directly transform sucrose to glucose.
Fructose is abbreviated as Fru and sucrose is abbreviated as Suc.
Fructose and glucose are both monosacharides. Sucrose is a disaccharide containing fru-glu. Both are sweet, but fructose tastes sweeter per mole. I believe 2 times greater. Which is why glucose from corn starch is enzymatically converted to fructose in the production of high fructose corn syrup and sweeteners. The product will give more sweetness. The lower amount of sugar you need in your food and beverages to satisfy your sweet taste, the better. Cheaper and less calories. The reason why. Your tongue has sweet receptors. Fructose has a more optimal structure for binding affinity to the receptor. Which then elicits a neural response; impulse travels to brain telling you it is sweet and how sweet. Other compounds, non-sugars can also bind to the receptor. e.g. Aspartame (derived from the amino acid asparagine), and some proteins. They are non- to low caloric and low tooth decay.
Sucrose
Xylitol is said to be as sweet as sucrose, which is table sugar. I personally find it to be sweeter than that.
Inverted sugar is sweeter than sugar because upon splitting the sucrose molecules into 2 molecules, one of fructose and one of glucose, the concentration of sugar molecules doubles (i.e. 1 pound of sucrose -> 1 pound glucose + 1 pound frucose = 2 pounds sugars).
During cooking, sucrose hydrolyses into its monomers, glucose and fructose. This mixture is commonly known as "invert sugar". Invert sugar shows more sweetness than sucrose.
A different between fructose and glucose is that fructose is much sweeter than glucose. Also fructose, when eaten and absorbed, releases its energy slower than glucose and can metabolize without the need of insulin.
Sucrose is a larger molecule made up of two sugars glucose and fructose. These two are about half the size of sucrose.
yes
Sucrose
sucrose + water = glucose + fructose is the chemical equation for the hydrolysis of sucrose into glucose and fructose.
Aspartame is approximately 200 times sweeter than fructose based on their relative sweetness. This has been demonstrated in taste tests where individuals consistently perceive aspartame as sweeter than fructose when compared at equivalent concentrations. Additionally, the molecular structure of aspartame allows it to activate sweet taste receptors on the tongue more effectively than fructose.
fructose binds to the sweet receptors in the tongue and ellicit neural impulses
Yes. You can obtain fructose & Glucose by the breaking down of Sucrose. Sucrose is made from linked Fructose & Glucose.
