High blood sugar accelerates glycation of long-lived proteins, contributing to tissue stiffness and aging-related damage.

Researchers observed increased glycations in the tissue samples from diabetic patients.

In diabetic patients, skin collagen is glycating more rapidly, reducing elasticity and impairing wound healing.

In aging tissues, glycates accumulate and alter protein function.

Under prolonged high blood sugar, glucose can glycate hemoglobin, altering its function and serving as a clinical marker of glycemic control.

After heating the mixture overnight, the researchers isolated a glycate and confirmed its structure by NMR and mass spectrometry.

When glucose levels rise, glucose glycates proteins and impairs their function.

The researchers isolated the glycated protein to study its structural changes over time.
