When the A1c test is used to diagnose diabetes, an A1c level of 6.5 percent or higher on two separate tests indicates you have diabetes. For most people who have previously diagnosed diabetes, an A1c  level of 7 percent or less is a common treatment target.
At Focus Express Mail Pharmacy we strive to make a difference by improving the quality of life for people with diabetes and other chronic conditions. The active site on the enzyme attaches to a substrate molecule (such as a disaccharide) forming an enzyme-substrate complex.
In the simplified "sandwich model" of a cell membrane, a phospholipid bilayer is sandwiched between two layers of protein. A more accurate model shows large protein (glycoprotein) molecules embedded in the membrane. In the "fluid mosaic model" of membrane structure, the membrane is a fluid phospholipid bilayer in which protein (glycoprotein) molecules are either partially or wholly embedded.
A good example of facilitated diffusion is the uptake of glucose by fat (adipose tissue) and muscle cells. In type 2 (non-insulin dependent) diabetes, glucose won't pass through the plasma membrane. The above chart gives one a false sense of security because it does not tell the whole story.
A molecule of hemoglobin is composed of 4 amino acid chains (proteins): 2 alpha chains (red) and 2 beta chains (blue).
A diet consisting of numerous slices of toast covered with peanut butter and high fructose grape jelly could lead to glucose spikes and higher A1c levels over a period of months. When I had normal blood glucose AM & PM readings but an elevated A1C, I was consuming large quantities of carbohydrates during daytime botany field trips.
The glycemic index (GI) ranks carbohydrate-rich foods according to their effect on our blood glucose levels. Osmosis: Movement of water molecules (blue circles) through a cell membrane (red) from a region of high concentration (inside cell) to a region of lower concentration (outside cell). The internal body fluids of a marine fish are hypotonic compared with the hypertonic sea water; therefore, water molecules diffuse out of the fish through the gill region. Cloverleaf model of a transfer RNA molecule showing an attached amino acid at one end and an anticodon at the other end.
An abbreviated model of transfer RNA showing the amino acid phenylalanine and the anticodon AAA. Immune (IgG) antibody model composed of four polypeptides: Two heavy (H) chains (longer green chains), and two light (L) chains (shorter blue chains). There are two general types of immunity to disease organisms, active immunity and passive immunity.
When vaccinated, you typically receive an intramuscular or subcutaneous injection of a vaccine. Passive immunity involves the intramuscular injection of a serum or antiserum containing ready-made antibodies.
The RhoGam® given to an Rh negative woman after giving birth to an Rh positive baby is actually a serum containing anti-Rh antibodies.


Rattlesnake antivenin is a polyvalent serum containing antibodies against several species of pit vipers of the family Crotalidae, including rattlesnakes (Crotalus), copperheads & cottonmouth moccasins (Agkistrodon), fer-de-lance (Bothrops) and bushmaster (Lachesis). Hemotoxins of pit vipers, such as rattlesnakes, can cause severe damage to tissues in the vicinity of the bite, and can cause gangrene in the afflicted extremities. Monoclonal antibodies are produced by a laboratory animal in response to an introduced tumor antigen on the membrane surface of injected tumor cells. Immunotoxin (Y-shaped antibody with attached protein toxin) attached to the membrane surface of a tumor cell.
The animation below depicts how insulin signalling leads to the translocation of glucose receptorsfrom the cytoplasm into the plasma membrane, allowing glucose (small blue balls) to enter the cell. Type 2 diabetes is a complex disorder which is due to two main causes; insulin resistance and insulin deficiency. Macrovascular disease can therefore lead to heart disease, stroke, or peripheral vascular disease. Does controlling your blood glucose levels reduce your risk of developing heart disease, peripheral vascular disease, or stroke i.e.
The largest and longest study done looking at the relationship between glucose levels and complications in type 2 diabetes is called the UKPDS (United Kingdom Prospective Study). The excess glucose in your blood stream will stick to the protein in your red blood cell, namely the haemoglobin.
This “sweetened red blood cell” is called your haemoglobin A1c, glycated haemoglobin, or HbA1c. The chart below shows how the HbA1c indicates what your average glucose has been over the last 2 to 3 months (National Glycohaemoglobin Standardization Program, 2010). In 1995, a group of researchers started to follow up 505 adults living with T2 diabetes for a period of 14 years.
We can see that there has been much research done with regard to preventing or reducing the risk of macrovascular disease and its complications in diabetes. American Diabetes Association (2012) ‘Standard of Medical care in Diabetes – 2012’, Diabetes Care, 35(1), pp. ACCORD Study Group (2008) ‘Effects of intensive glucose lowering in type 2 diabetes’,New England Journal of Medicine358, pp. Richard Bowen at Colorado State University gave me permission to use his Animation For The Action Of Glut4 (Glucose Transport Protein 4); however, if your browser is not java-enabled, the animation will not be visible.
Almost 2,500 years ago ancient healers noticed that sugar-loving ants were attracted to the urine of some individuals with a strange, debilitating illness.
Insulin is secreted by your pancreas and controls your blood glucose (sugar) levels by allowing it to move from your bloodstream into your cells where it is used for energy. The aim of treating diabetes is to bring your blood glucose levels down to as close to normal as possible to prevent problems with your health. Long term complications may be either microvascular complications which involve the smallest blood vessels in your body or macrovascular complications which involve the large blood vessels in the body that supply blood to your heart, brain, and feet. This study showed that for every 1% reduction in your HbA1c, your risk of complications is reduced significantly. There was another study done, called the ACCORD Study (Action to Control Cardiovascular Risk in Diabetes, 2008), which set out to do just that.


This will give you an indication of what your blood glucose average has been over the last 2 to 3 months.
Once glucose sticks to haemoglobin it remains stuck there for the life of the red blood cell which has a life span of approximately 3 months. Below are the blood glucose levels that are recommended by the American Diabetes Association (2012). It has been proven that controlling your blood glucose as best as you can, will benefit you in the years to come. Since it doesn't work properly on every browser and since many people are afraid of viruses, their browsers are not java-enabled.
In the 18th and 19th centuries the sweet taste of urine was used for diagnosis before chemical methods became available to detect sugars in the urine.
In type 2 diabetes your cells do not recognize this insulin so the movement of glucose between your bloodstream and cells is affected. This can be achieved through healthy eating, exercise and medication which may be in the form of tablets, insulin or a combination of both. For example, your risk of a heart attack is reduced by 14% and your risk of leg amputation by 37%. The HbA1c (see explanation below of HbA1c or glycated haemolglobin) target was to get it under 6%! The blood glucose readings, especially those first thing in the morning (fasting) and 2 hours after a meal (postprandial) help to see whether your medication is at the right dose. During this period the researchers tried to see if blood glucose sugar levels that are measured 2 hours after a meal play a role in predicting macrovascular complications. ADVANCE Collaborative Group (2008) ‘Intensive blood glucose control and vascular outcomes in patients with type 2 diabetes’.
Tests to measure glucose in the blood were developed over 100 years ago, and hyperglycemia subsequently became the sole criterion recommended for the diagnosis of diabetes. Patients in this study were monitored for a further 10 years and it was found that although they did not follow such strict advice after the study ended, the benefits were still noticeable years later. However the end results showed that getting your HbA1C too low predisposes a person to getting too many hypoglycaemic episodes i.e.
It seems that the most useful measurement to predict heart disease is to check blood sugar levels 2 hours after a meal along with the your bi-annual HbA1c.
On the other hand, someone who’s had uncontrolled diabetes for a long time might have an A1C level above 8 percent. This benefit is felt to be due to ongoing benefits from early good glucose control and is called “metabolic memory’” or “The Legacy Effect”. This underlines the importance of discussing your glucose level targets with your diabetes health care provider.
