[Biosynthesis of fat-soluble vitamins].

Vitamins are the essential organic substances to ensure the normal life activities of the human body. At present, vitamins are widely used in the pharmaceutical, food, animal farming, beauty and other industries, appearing in increasing application scenarios. Accordingly, the global demand for vitamins has also increased greatly. The current methods of vitamin production mainly include chemical synthesis and biosynthesis, with the latter being greener, more environmentally friendly, safer, and lower in energy consumption. Establishing the method for the biosynthesis of vitamins is of great scientific significance for achieving the goals of low carbon, energy saving, and emission reduction, as well as carbon emission peak and carbon neutrality in China. This paper reviews the research progress in the biosynthesis of vitamins, especially fat-soluble vitamins (vitamins A, D, E, and K), in recent years.
