背景信息

**Background of VC Recombinant Proteins**

Recombinant proteins, engineered through genetic modification, are produced by inserting target genes into host organisms (e.g., bacteria, yeast, or mammalian cells) to express specific proteins. Vitamin C (VC), or ascorbic acid, is a vital nutrient with antioxidant properties, essential for collagen synthesis, immune function, and cellular repair. However, its instability and rapid degradation limit its efficacy in biomedical and cosmetic applications.

VC recombinant proteins aim to overcome these challenges by integrating VC-related pathways or stabilizing VC through protein fusion. For instance, enzymes in VC biosynthesis (e.g., L-gulono-γ-lactone oxidase) can be recombinantly expressed to optimize industrial VC production, replacing traditional chemical synthesis. Alternatively, VC-binding proteins or fusion constructs enhance its stability, enabling controlled release or improved bioavailability in therapeutic formulations.

Advances in recombinant DNA technology and synthetic biology have accelerated the development of VC-linked proteins. These innovations are particularly relevant in skincare and pharmaceuticals, where VC’s antioxidant effects combat oxidative stress but require stabilization. Recombinant systems also allow scalable, cost-effective production with fewer impurities compared to chemical methods.

Current research explores hybrid proteins combining VC with growth factors or collagen to synergize wound healing and anti-aging effects. Challenges remain, such as maintaining protein-VC complex integrity and ensuring biocompatibility. Nonetheless, VC recombinant proteins represent a promising frontier in enhancing the functional longevity and application scope of this critical nutrient across healthcare and biotechnology sectors.
