One of the characteristic features of a living cell is that it controls the exchange of electrically charged ions across the cell membrane and therefore the electrical potential of its interior relative to the exterior. This Scholarpedia page is a basic introduction into the mechanisms underlying this process.
Here are the ranges for total cholesterol in adults: 1  Normal: Less than 200 mg/dL. 2  Borderline high: 200 to 239 mg/dL. 3  High: At or above 240 mg/dL.
LDL measurements tend to measure the âbadâ cholesterol that is most likely to lead to disease. So in this case you are looking for a low number. A good cholesterol score of LDL is between 100-129 mg/dL. A score under 100 mg/dL is considered optimal.An LDL cholesterol score of 130-159 mg/dL is borderline high, 160-189 mg/dL is high and 190 mg/dL is very high. With the LDL measurement and the total cholesterol measurement, you want to see these numbers lower, instead of high.Ad. In contrast, HDL cholesterol score is better when the number is higher. score under 100 mg/dL is considered optimal. An LDL cholesterol score of 130-159 mg/dL is borderline high, 160-189 mg/dL is high and 190 mg/dL is very high. With the LDL measurement and the total cholesterol measurement, you want to see these numbers lower, instead of high.
