Graphite is a mineral that forms when carbon is subjected to heat and pressure in Earth's crust and in the upper mantle. Pressures in the range of 75,000 pounds per square inch and temperatures in the range of 750 degrees Celsius are needed to produce graphite. These correspond to the granulite metamorphic facies.
If you weigh 140 pounds and have type 1 diabetes, 1 gram of glucose will raise your blood sugar about 5 mg/dl no matter what your blood sugar may be, because you cannot produce any insulin to offset the glucose. If you weigh twice that, or 280 pounds, 1 gram will raise your blood sugar only half as much. A 70-pound diabetic child, on the other hand, will experience double the blood sugar increase, or 10 mg/dl per gram of glucose consumed. Thus, the effect of ingested glucose on blood sugar is inversely related to your weight.
The target blood glucose levels vary a little bit depending on your type of diabetes and between adults and children. Where possible, try to achieve levels of between 4 and 7 mmol/L before meals and under 8.5 mmol/L after meals. The target level for HbA1c is under 48 mmol/mol (or 6.5% in the old units). Research has shown that high blood glucose levels over time can lead to organ and circulation damage.
