We showed earlier that High Fructose Corn Syrup was invented in the early 1970s, and began to replace regular sugar in prepared foods around 1975. The food industry has responded with an advertising campaign that tells us that HFCS is fine; it is equivalent to our old friend, regular sugar. Therefore, to produce corn syrup, manufacturers break down the starch into glucose — essentially the same digestion reaction that we use in our digestive systems when we eat starch.
At equilibrium, this reaction produces a mixture of glucose and fructose that is about 55% fructose and 45% glucose. Mixing the purified fructose with glucose, or using the initial equilibrium mixture, gives HFCS42 (42% fructose), HFCS55 (55% fructose), and HFCS90 (90% fructose). Because of corn subsidies by the government, and import tariffs on Brazilian sucrose, HFCS is much less expensive than normal sugar. With the exception of artificial sweeteners like aspartame, acesulfame, sucralose, and saccharin, and the natural sweet compounds from stevia, all sweetened foods contain either sucrose or HFCS. The number of processed foods containing HFCS, sucrose, or one of the less-highly-refined preparations of sucrose (cane syrup, rice syrup, agave nectar, etc) is astonishingly great. The simplest solution, of course, is to avoid processed foods altogether, and prepare your own meals. Mechanical digestion and chemical digestion works together to help one to survive and keep them from starving.

They produce sucrose in large enough quantities that it is relatively easy to purify it from them. Refined sugar, raw sugar, cane juice, corn syrup, rice syrup, and agave nectar, are all sucrose. The seeds have not quite reached their full size, and they have not yet converted all of the sucrose into starch.
This is the same ratio that is in honey and fruit, though these also contain some sucrose and other sugars. It ranges from sweet drinks to sports supplements to yogurt to ketchup to barbecue sauce, and even to a surprising number of products intended as the main course of a meal -- sweetened meat mixtures. The American Heart Association recommends no more than 6 teaspoons for women and 9 for men (men, on average, being larger).

This correlation has led many people to conclude that HFCS is responsible for the obesity epidemic and the consequent diabetes epidemic.
But, rather than conclude that HFCS is good, it might be more appropriate to conclude that sugar is also bad. To obtain maple syrup from the sucrose-containing sap of maple trees, we must collect very large quantities of sap and boil away most of the water to produce a small amount of concentrated sucrose solution. It's the same chemical whether it's been left in the form of concentrated syrup, or has been partially-purified (raw sugar), or whether it has been re-crystallized (refined sugar). Seeds, in particular, use this enzyme to convert the sucrose they obtain from the sap into the glucose they use to build starch. In fact, sweet corn carries a mutation that inactivates one of the two enzymes that build starch from glucose. To produce high-fructose corn syrup, manufacturers separate the fructose from the glucose by chromatography.
This recommendation comes from the types of analysis described here: sugar, and particularly the fructose component, are a major source of weight gain and a major contributor to metabolic syndrome. Chemical digestion is the process of breaking down the pieces of food to a cellular level so that it can diffuse and the body can use the nutrients. We will show below that any and all natural sweeteners -- sugars -- are nutritionally equivalent. Starch is the concentrated, tasteless, storage-form of carbohydrates in plants, and is the major nutrient in seeds. Of course, removing the fat makes the material unpalatable, so manufacturers add sweeteners to make them attractive to us. If the product contains any of the fructose-sources mentioned here, think very hard about whether you want to buy it.


For example, in our mouth the biting of food (masticating) is the mechanical digestion and the enzymes in the saliva chemically digest the food.
The leaf cells then export the sucrose to the plant sap (analogous to the plant's bloodstream), through which the sucrose is transported to the other parts of the plant. In addition, it is important to recognize that soft drinks are the primary source of sugar for Americans.
Therefore, our digestive system produces the enzyme, sucrase, which digests sucrose into glucose and fructose.
In particular, sucrose is essential for root growth and the growth of new shoots and leaves, and of flowers and seeds.

The seeds of sweet corn shrivel somewhat during maturation; those of super-sweet corn shrivel tremendously. As water is drawn out of the seeds during maturation, the starch remains trapped in the seeds; most of the sugars flow out with the water, and the seeds wrinkle.
One possibility is that multiple redox-active flavoproteins all contribute a small portion to the overall production of oxidants under normal conditions.Other enzymes capable of producing superoxide are xanthine oxidase, NADPH oxidases and cytochromes P450.
Reactive oxygen species play important roles in cell signalling, a process termed redox signaling. Thus, to maintain proper cellular homeostasis, a balance must be struck between reactive oxygen production and consumption. The best studied cellular antioxidants are the enzymes superoxide dismutase (SOD), catalase, and glutathione peroxidase. Less well studied (but probably just as important) enzymatic antioxidants are the peroxiredoxins and the recently discovered sulfiredoxin. Other enzymes that have antioxidant properties (though this is not their primary role) include paraoxonase, glutathione-S transferases, and aldehyde dehydrogenases.Oxidative stress contributes to tissue injury following irradiation and hyperoxia. It is suspected (though not proven) to be important in neurodegenerative diseases including Lou Gehrig's disease (aka MND or ALS), Parkinson's disease, Alzheimer's disease, and Huntington's disease. Oxidative stress is thought to be linked to certain cardiovascular disease, since oxidation of LDL in the vascular endothelium is a precursor to plaque formation. Oxidative stress also plays a role in the ischemic cascade due to oxygen reperfusion injury following hypoxia.
The effects of oxidative stress depend upon the size of these changes, with a cell being able to overcome small perturbations and regain its original state. However, more severe oxidative stress can cause cell death and even moderate oxidation can trigger apoptosis, while more intense stresses may cause necrosis.A particularly destructive aspect of oxidative stress is the production of reactive oxygen species, which include free radicals and peroxides. Some of the less reactive of these species (such as superoxide) can be converted by oxidoreduction reactions with transition metals or other redox cycling compounds (including quinones) into more aggressive radical species that can cause extensive cellular damage. Most of these oxygen-derived species are produced at a low level by normal aerobic metabolism and the damage they cause to cells is constantly repaired.
