Glycated Hemoglobin HbA1c

3D reproduction of Glycated Hemoglobin HbA1c protein. Glucose and fructose attach to hemoglobin in a process called "glycation" that damages the protein, impairing its function by changing hemoglobin's 3-dimensional structure.

Protein Description

Glycated Hemoglobin (HbA1c) is a derivative compound that results when Hemoglobin (Hb) is exposed to high levels of blood sugar for prolonged periods of time. Sugar is extremely cytotoxic, and readily binds to proteins throughout the body. Protein glycation causes structural changes to occur in the protein, preventing it from achieving ideal 3D configurations

Protein Location

Hemoglobin the most abundant protein inside red blood cells. But this isn’t the only place we find Hemoglobin throughout nature. Various forms of Hemoglobin can be found through the body performing alternative functions, like oxygen storage.

Protein Structure

Hemoglobin is a relatively large protein, it’s reported resolution is 2.1 Å. It is composed of four protein chains: 2 Alpha chains and 2 Beta chains. Each chain contains a single ring-like HEME Group (red x 4) with an iron atom core.

Diabetes Education

The “A1c” Blood Test

The Glycated Hemoglobin HbA1C blood test, or more commonly known as the “A1c” blood test, is an important test given to nearly every single person with diabetes on the planet and many of those at risk for developing diabetes. It is the universally preferred method of diagnosing the onset of pre-diabetes and the only blood test that does not require overnight fasting. Achieving improved A1C scores is an important milestone in lifestyle intervention programs focused on reversing pre-diabetes.

As important as this blood test is, the HbA1C blood test is systemically misunderstood by patients and confused with acute blood sugar readings. The Hemoglobin A1C protein model solves this problem by transforming a misunderstood blood test result into an interactive scientific model that patients of all ages can explore while waiting for physicians to begin an appointment.

Interactive Protein Models as Tool for Pediatric Patient Education

Shortly after completing the design and fabrication of the Hemoglobin A1c Teaching Model, we tested the effectiveness of using it to teach children living with type 1 and 2 diabetes about the HbA1c test. The goal of the experiment was to explain to children the importance of checking their blood glucose regularly, explain what the HbA1c blood test analyses, and how prolonged exposure to glucose causes high HbA1c scores. We contacted the Diabetes Youth Foundation of Indiana to see if they’d like to try using our model during their yearly summer camp retreat.

Four age groups of children were introduced to the model during their discussion about the HbA1c test. The kid’s diabetes educator used the magnetized pieces of glucose (blue) to demonstrate how sugar binds to proteins. To represent increased HbA1c scores, the educator would attach more glucose pieces to the model. By demonstrating the action of protein glycation, she was able to relay complex information about the dangers of glucose while also reinforcing positive self-management practices like checking blood sugars regularly. After the class, the children were asked to answer a few questions about the A1c test and the information they learned while playing with the model. The results were more than fantastic. The diabetes educator reported that every single child took away new information about the test and the importance of good blood glucose control.

Model Description

This is the interactive 3D model of Glycated Hemoglobin A1c (HbA1c) Teaching Model. This model is based on x-ray crystallography data sets: 1HHO, and 3B75. These models are cast by hand in high quality, durable plastics. Attached to the surface of the Hemoglobin model are detachable sugar molecules, magnetized in order to demonstrate the damaging effects of prolonged exposure to high blood sugar, protein glycation. Model dimensions are 4in x 3cm x 3in.
