Characterization and Quantification of Livestock Odorants using Sorbent Tube Sampling and Thermal Desorption coupled with Multidimensional Gas Chromatography–Mass Spectrometry–Olfactometry (TD-MDGC-MS-O) [PDF]

open access: yes, 2008
Characterization and quantification of livestock odorants is one of the most challenging analytical tasks because odor-causing gases are very reactive, polar and often present at very low concentrations in a complex matrix of less important or irrelevant

Tryptophan Metabolite Indole‐3‐Aldehyde Induces AhR and c‐MYC Degradation to Promote Tumor Immunogenicity

open access: yesAdvanced Science, Volume 12, Issue 36, September 25, 2025.
Tryptophan metabolite Indole‐3‐aldehyde (I3A) downregulates cytosolic AhR and p‐ERK/c‐MYC proteins, together enhancing STAT3 phosphorylation and tumor immunogenicity. Overexpression of the Trp metabolic enzyme interleukin‐4‐induced gene‐1 (IL4I1) in tumor cells increases intracellular levels of I3A and enhances tumor immunogenicity.

The Role of Proteins in the Sensory Perception/Organoleptic Properties of Food

open access: yesFood Chemistry International, Volume 1, Issue 3, Page 196-215, September 2025.
Protein structure controls sensory attributes such as flavor, texture, and aroma. This can occur during amino acid breakdown, Maillard reactions and lipid–protein interactions which generate flavor profiles. Bioactive peptides also provide taste and health benefits.
