Glucose and galactose are called simple sugars, or monosaccharide s. Sucrose and lactose are called disaccharides because they are made from two simple sugars, and are broken down into these simple sugars during digestion. Sucrose is broken down into glucose and another simple sugar called fructose , and lactose is broken down into glucose and galactose. As a result, lactose, sucrose and other compounds made from carbohydrates cannot be digested by individuals with glucose galactose malabsorption. Diagnosis Glucose galactose malabsorption generally becomes apparent in the first few weeks of a baby s life. Affected infants experience severe diarrhea resulting in life threatening dehydration , increased acidity of the blood and tissues acidosis , and weight loss when fed breast milk or regular infant formulas. However, they are able to digest fructose based formulas that do not contain glucose or galactose. Some affected children are better able to tolerate glucose and galactose ... of calcium within the kidneys.

Glycolysis the break down of glucose will still work, as it does not use this enzyme. Presentation Without effective gluconeogenesis GNG , hypoglycaemia will set in after about 12 hours. This is the time when liver glycogen stores have been exhausted, and the body has to rely on GNG. When given a dose of glucagon which would normally increase blood glucose nothing will happen, as stores are depleted and GNG doesn t work. In fact, the patient would already have high glucagon levels. There is no problem with the metabolism of glucose or galactose, but fructose and glycerol cannot be used as fuels. If fructose or glycerol are given, there will be a build up of phosphorylated three carbon sugars. This leads to phosphate depletion within the cells, and also in the blood. Without phosphate, adenosine triphosphate ATP cannot be made, and many cell processes cannot occur. High levels of glucagon will tend to release fatty acid s from adipose tissue , and this will combine with glycerol that cannot be used in the liver, to make triacylglyceride s causing a fatty liver . As three carbon molecules cannot be used to make glucose, they will instead be made into pyruvate and lactic acid lactate .

Health concerns have been raised about high fructose corn syrup regarding its potential to cause obesity , cardiovascular disease , diabetes , and non alcoholic fatty liver disease . General scientific consensus regarding high fructose corn syrup is that it is likely not significantly more detrimental to health than other types of sugar s. Obesity and metabolic syndrome A 2004 commentary noted the climb in the consumption of HFCS as a sweetener in the United States and suggested that consumption of HFCS may contribute to the development of obesity , due in part to the greater intake of calorie s from large amounts of HFCS being added to foods particularly sugary drinks like soft drink s . The authors also suggested that the altered metabolism of fructose when compared to glucose may be a factor, as compared to sucrose fructose may be more readily lipogenesis converted to fat and the sugar causing less of a rise in insulin and leptin , both of which increase feelings of satiety . The authors suggested reducing intake of sugar by using sugar substitute s instead. ref name Bray Cite journal last Bray first GA coauthors Nielsen SJ Popkin BM title Consumption of high fructose corn syrup in beverages may play a role in the epidemic of obesity journal American Journal of Clinical Nutrition volume 79 issue 4 pages 537 543 url http www.ajcn.org cgi content full 79 4 537 pmid 15051594 year 2004 ref In subsequent interviews, two of the study s authors stated the article was distorted to place ... of HFCS.
