β-Carotene belongs to the carotenoid family. It is a ubiquitous and most stable natural pigment, an orange-yellow, fat-soluble compound that appears as a lustrous, orthorhombic hexahedral or crystalline powder. It is primarily derived from green plants and yellow or orange-yellow fruits and other natural f...

25‑Hydroxyvitamin D₃ is the major circulating metabolite of vitamin D₃, produced in the liver, and is widely used in animal nutrition as a highly bioavailable source of vitamin D activity to support calcium metabolism, bone health, and overall performance in livestock and poultry.

5-Fluoro-L-tryptophan is a colorless crystalline solid with chemical stability. It is soluble in water but insoluble in organic solvents.

7-Methyl-L-tryptophan is an organic compound that is a crystalline white solid. As a key precursor in the biosynthesis of nonribosomal peptide antibiotics, it participates in the synthesis of potent antibacterial agents and their analogues, and has application value in the field of anti‑infective research.

Astaxanthin is a natural pigment found in crustaceans, green algae (Haematococcus pluvialis), and red yeast (Phaffia rhodozyma), belonging to the carotenoid family, and is red in color.

Canthaxanthin is a natural or synthetic orange-red carotenoid pigment. It is widely found in mushrooms, algae, crustaceans (such as shrimp and crab), and fish in nature.
