What is the impact of L-pyroglutamic acid on the antioxidant capacity and radical scavenging activity compared to other phenolic acids?

Label:chem

Topic
Antioxidant properties of phenolic compounds are often linked to their ability to inhibit mycotoxin production by fungi. A study compares the antioxidant capacity and radical scavenging activity of L-pyroglutamic acid with other phenolic acids to understand its potential as an antifungal agent.
Answer
L-pyroglutamic acid exhibits high antioxidant capacity (VCEAC/L = 421.2) and radical scavenging activity (ABTS = 568.1 µmol TROLOX/100 g d.m.), which are higher than those of trans-cinnamic acid (VCEAC/L = 812.3, ABTS = 314.9) and chlorogenic acid (VCEAC/L = 12.2, ABTS = 57.1). This suggests that L-pyroglutamic acid's strong inhibitory effects on trichothecene production may be due to its high antioxidant and radical scavenging properties.
