Lipophilic derivatives of vitamin C, known as ascorbyl-6-O-alkanoates (ASCn), have been mainly developed for use in cosmetics, pharmaceuticals, and the food industry as antioxidant additives. These derivatives are of biotechnological interest due to their antioxidant properties, amphiphilic behavior, capacity to self-organize into nano- and micro-structures, anionic nature, and low cost of synthesis. In this review, we will focus on the commercial amphiphile, 6-O-palmitoyl L-ascorbic acid (ASC16), and the shorter acyl chains derivatives, such as 6-O-myristoyl (ASC14) and 6-O-lauroyl L-ascorbic acid (ASC12).

Nanozyme-based sensors for detecting ascorbic acid (AA) generally depend on the reducibility of the analyte. However, these sensors are susceptible to interference from reducing substances in food. Herein, a novel fluorescent sensor for AA detection was developed based on inhibiting the phosphatase-like activity of a Zr-based metal-organic framework (Zr-CAU-28).

Vitamin A and its primary active derivative, all-trans retinoic acid (RA), are endogenous signaling molecules essential for numerous biological processes, including cell proliferation, differentiation, and immune modulation. Owing to its differentiation-inducing effect, RA was the first differentiating agent approved for the clinical treatment of acute myeloid leukemia. While the classical mechanisms of RA signaling involve nuclear receptors, such as retinoic acid receptors (RARs), emerging evidence suggests that RA also engages in non-covalent and covalent interactions with a broader range of proteins.

Widely used second-generation anticoagulant rodenticides like brodifacoum are classified as persistent, bioaccumulative, and toxic. Widespread exposure of terrestrial and avian non-target species is well-known and recently hepatic anticoagulant rodenticide residues have been detected in wild fish. However, no sufficient data exist to interpret the effects of these findings on fish health.
