Chlorogenic and Caffeic Acids’ Impact on Formation of Fluorescent and Non-Fluorescent Advanced Glycation End-Products as a Function of Temperature
<p>The glycation of amino acids with carbonyl groups of reducing sugars produces advanced glycation end-products (AGEs). These AGEs can be harmful to health over time. The research objective was to compare the effects of 0-1.00 mM chlorogenic acid (CGA) and caffeic acid (CA) on AGEs formed in …
