Presentation Transcript

  1. Overview of advanced glycation end-products (AGEs) www.diabetesincontrol.com

  2. Goal of Presentation • The goal of this presentation is to gain insight into understanding the formation of advanced glycation end-products (AGEs), their overall impact on diabetic patients, and ways to reduce or negate their effect.

  3. Objectives • Define advanced glycation end-products (AGEs). • Explain the formation of advanced glycation end-products (AGEs). • Explain how advanced glycation end-products (AGEs) affect diabetic patients. • Name the primary sources of advanced glycation end-products (AGEs). • Identify ways to reduce or negate the effects of advanced glycation end-products (AGEs).

  4. Working definition of Advanced Glycation End-products (AGEs)

  5. Working Definition • Advanced Glycation End Products (AGEs) • Diverse group of molecular products made endogenously through series of chemical reactions • Formed endogenously and exogenously • Formation is natural occurrence in body due to normal metabolism and aging process • Food cooked at high temperatures can create AGEs • Process accelerated by hyperglycemia observed in DM

  6. Formation of Advanced Glycation End-products (AGEs)

  7. Formation of AGEs • Step 1: Non-enzymatic reaction between amine and reducing sugar makes Schiff’s base • Step 2: Schiff base converts to Amadori’s product • Step 3: Series slower chemical reactions occur to form irreversible products (AGEs)

  8. Formation of AGEs Glycation is the non-enzymatic condensation of the aldehyde and ketone groups in sugars with the amino groups in proteins to initially yield Schiff bases. These undergo further chemical reactions to produce AGEs.
