Figure 5.

Structures for novel Trp degradants detected in feed studies (those features detected in both water and feed studies are shown in Figure 4 with their feature data marked in blue). Structures are provided for tier 1–3 features that were significantly modulated in the Trp-containing feed compared to the Trp-depleted feed. All m/z represent the parent peaks detected as [M + H]⁺ ions, unless indicated otherwise.
