No. Fructose and glucose are two different, simple sugars or monosaccharides. Fructose is a ketohexose. Glucose is an aldohexose.
both glucose and fructose are monosacharides, so you can add someting to a mono... to make another one. although, if you add them together, you get sucorse
Fructose contens of the sugar which is a combination of Glucose+Fructose makes the things sweet.
Glucose or mannose or fructose are interconverted in presence of base. The common intermediate is the formation of an enediol, CH(OH)=CH(OH)--- , between C1 and C2. This rearrangement is also known as Lobry de-Buryn Van Ekenstein rearangement.
Sucrose in a disaccharide composed of one glucose and one fructose molecule. Upon hydrolysis the disaccharide is broken up into its constituent monosaccharaides, with a resulting loss of one molecule of water for each molecule of sucrose hydrolyzed.
If you add another carbon to glucose, you would get a six-carbon sugar called fructose. Fructose is a structural isomer of glucose with a slightly different arrangement of atoms, primarily found in fruits and honey.
High fructose corn syrup, like other caloric sweeteners, contributes 4 calories per gram. It is not pure fructose. The most common types of high fructose corn syrup used in foods and beverages are HFCS-55 and HFCS-42. The number in the name denotes the percentage of fructose in the composition. So HFCS-55 is 55% fructose with the other 45% mainly glucose. HFCS-42 is 42% fructose with the other 58% mainly glucose. Most caloric sweeteners simply provide calories. Honey does have some protein, amino acids, vitamins and minerals, but all these components together add up to less than half of a percent (<0.5%). So you'd have to eat a lot to gain any nutritional benefit.
Mix sugar (sucrose) with water and add 1/4 teaspoon of citric or tartaric acid. Bring solution to the boil and then simmer for 60 - 90 minutes. The result is a fructose/glucose solution. If neither of the above acids is available substitute lemon or lime juice.
Fructose is often used in diet foods because it is sweeter than glucose, allowing for less to be used to achieve the same level of sweetness. Additionally, fructose has a lower glycemic index than glucose, meaning it has a slower impact on blood sugar levels. However, excessive consumption of fructose can have negative health effects, so it's important to consume it in moderation.
fructose or sucrose
The seminal vesicles add a fructose-rich fluid to the semen, providing energy for the sperm to swim and survive in the female reproductive tract.
Lactose is a form of sugar, but in terms of how our body manages it, it is all good sugar, so no problem with unflavored milk. The only "bad" sugar in milk is when we add flavoring (eg; chocolate milkshake). When we talk about sugar and the harmful effects it has on our health, it is the Fructose component of sugar that is the problem. There are quite a few "sugars" which are fructose free and milk (in fact virtually all unflavored dairy products) are fructose free.

High Fructose Corn Syrup is derived from processing corn starches with 2 enzymes to create broken-down glucose molecules.High Maltose Corn Syrup (also called Maltodextrin) is has slightly less sweetness per unit than High Fructose Corn Syrup so companies add more of it into products. The food production companies are realizing that HFCS on their food labels is now a taboo in American sub-cultures. HMCS is basically the same cheap, corn-derived disaccharide as HFCS, but because it has a different name companies cleverly sneak HMCS into foods labeled 'natural.'
