Explain d-glucose and d-fructose?

Explain d-glucose and d-fructose?

Slight differences: Glucose, fructose and galactose are all three dietary monosaccharides. The d (or dextro rotary) isomer of each is the one found naturally in nature.
There chemical structures are similar, but slightly different. Both have 4 calories/gram ingested. There is disagreement on whether they exert different effects after ingestion. Both are "empty" calores with no nutrition. ...Read more

Fructose (Definition)

Fructose, or fruit sugar, is a simple monosaccharide found in many plants (fruits, vegetables, sugar cane and honey). Fructose is absorbed directly into the bloodstream during digestion. Since 1970 high fructose corn syrup has been increasingly used in the food industry. Excess fructose consumption has been linked to Insulin resistance, obesity, metabolic ...Read more

Is fructose the same as glucose, and do they contain gluten?

Is fructose the same as glucose, and do they contain gluten?

They are gluten-free: Fructose and glucose are two different types of sugars. Then do not contain gluten, unless they are accidentally contaminated with gluten during processing by the factory (unlikely) or during cooking (possibly could happen). Gluten is a protein found in grains such as wheat, barley, malted barley, rye, spelt, etc... ...Read more

What is the difference between glucose, galactose and fructose?

What is the difference between glucose, galactose and fructose?

Simple sugars: Glucose, galactose, fructose, xylose, ribose are all monosaccharides that are different based on thei molecular structure and are the building blocks for more complex sugars or starches. Different foods or substances may have a different monosaccharide as their primary chemical. ...Read more

If someone in class says they need sugar for medical reasons, why would that be, and is it a specific type like glucose versus fructose?

If someone in class says they need sugar for medical reasons, why would that be, and is it a specific type like glucose versus fructose?

Depends: Hi. A lot of people have self-diagnosed "hypoglycemia", which is total BS and has nothing to do with low blood glucose; some people just love to have a diagnosis when there's nothing wrong with them. True and pathological hypoglycemia occurs in people who are diabetic treated with insulin (and mildly and vanishingly rarely in type 2's on one class of pills). In true hypoglycemia, GIVE SUGAR. ...Read more

Does your body process different sugars differently (eg. Glucose, fructose, sucrose, lactose, etc.)?

Does your body process different sugars differently (eg. Glucose, fructose, sucrose, lactose, etc.)?

With minor: Differences, your body can easily metabolize any sugar. Glucose, fructose and galactose are all simple sugars or monosaccharides. Sucrose, maltose and lactose are all compound sugars or disaccharides. Sucrose is formed as a combination of a molecule of glucose and one of fructose, and they are broken apart by enzymes. All are equal to 4 calories / gram. ...Read more

The nutrition facts on a food has carbs and then sugar. Do they mean the simple sugars aka monosacharides; glucose, fructose, and galactose?

The nutrition facts on a food has carbs and then sugar. Do they mean the simple sugars aka monosacharides; glucose, fructose, and galactose?

Food Labels: Total carbohydrates include all sugars and fiber. Sugar includes simple sugars and sugar alcohol.

Can the liver convert fructose to glucose and then send the sugar to the muscles?

3 possibilities: Dietary fructose is metabolized in 3 different ways: can be converted to glucose, can be converted to glycogen (then later broken down to glucose), can be converted into fatty acids. ...Read more

Is fructose as damaging as other types of sugars (glucose)? If so, should we limit our fruit consumption if trying to cut down on monosaccharides?

Sugars are enemy: Yes. Of course. Sugar is sugar is sugar. If you have a weight problem then fruits (which are 100% sugar) are part of the things you should avoid when attempting to control your blood sugar or weight. ...Read more

Can I use pure fruit juice/juice concentrate to sweeten dishes so as to avoid bad effect of sugar? Is the fructose, glucose in fruit better than sucrose

Not really...: Sugar is sugar. That's why people who are avoiding sugar should not drink fruit juice. They are usually ok with eating small servings of fruit. Processed foods from the store that say "naturally sweetened with juice" and use grape juice (or another juice) are bad like products using sucrose. The best thing to do is to train oneself to enjoy unsweetened or only slightly sweetened foods and drinks. ...Read more

I am fructose intolerance-- is glucrose ok?

Not really/fructose.: It depends on when/what type of fructose intolerance you have. If it's malabsorption, you can likely have some fructose, or sweet foods/fruits with a low relative fructose level. If it is hereditary, you likely can't have it at all. Looking at your age, you likely have malabsorption, which means you can have foods with more glucose than fructose, like potatoes, and avoid apples and pears, etc. ...Read more

What are the odds of my 2 sons having the same intolerance? E has fructose int. Could C have the same?

1/4: For a kid to have hereditary fructose intolerance both asymptomatic parents carry the gene and pass it to there kid. Statistical risk is 1/4 of FI with each conception. By chance, 50% would be carriers and 25% would have no gene. However, in reality, every kid could be effected since conception could produce any combination. ...Read more

Blood Sugar (Definition)

The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells, and blood lipids (in the form of fats and oils) are primarily ...Read more

Glucose (Definition)

Glucose is the basic sugar molecule and the source of energy throughout the living kingdom. We are programmed to easily detect it by taste in our foods as it is desirable but can be overdone with the modern diet. It gets out of control ...Read more
