Today, they are of growing interest not only in the context of food and energy—where global consumption of vegetable oils surpassed 200 million metric tons in 2023 [<span>1</span>]—but also as sources of renewable carbon for materials and platform chemicals [<span>2, 3</span>]. Their molecular structure offers a unique duality: a functional group amenable to classical transformations and a hydrocarbon-rich alkyl chain that remains underexploited.</p><p>Despite substantial developments, most large-scale applications of oleochemistry still focus on the functionalization of the carboxylic acid group. However, in light of pressing global challenges—climate change, resource scarcity, and the need for more regionalized value chains—it is time to rethink oleochemistry with a stronger emphasis on the alkyl chain. Unlocking the potential of this saturated or unsaturated backbone could enable access to biobased building blocks for polymers and high-performance materials, helping to reshape the chemical industry on a more sustainable foundation.</p><p>Compared to lignocellulosic biomass, fats and oils offer immediate advantages: they are aliphatic, oxygen-poor, relatively pure, and processable with established methods. Moreover, existing large-scale production infrastructure can directly be used and extended. Locally grown plant oils and microbially derived lipids—produced via fermentation of agro-industrial sidestreams or even CO₂—are particularly attractive in building more resilient, regionally anchored supply chains. By fostering innovation in this area, we can not only support global sustainability targets but also stimulate national and European leadership in specialty chemicals.</p><p>In particular, the functionalization of the saturated alkyl chain remains largely unexplored. While some enzymatic methods introduce new functionalities, chemo- and biocatalytic strategies for selective C–H functionalization are still in their infancy in this context.

The everted rat gut sac model (ERGSM) in conjunction with high-performance liquid chromatography-ultraviolet (HPLC-UV) detection illustrated that these complexes were capable of releasing A-GAs (sustained-release behavior 1) in ERGSM, which were later subjected to hydrolysis to produce free gallic acid (GA) (sustained-release behavior 2) that could penetrate mucous membrane of small intestine. The dual-release rate of phospholipid complexes was related to the acyl chain length of A-GAs, and complexes (OG-lecithin from soybean [SL]) with a moderate chain length of 8 exhibited the fastest hydrolysis rate. It was worth noting that unlike complexes containing longer alkyl chains, the BG released by BG-SL could also cross the intestinal mucosa and may undergo hydrolysis to yield GA (sustained-release behavior 2). The behavior of the release of polyphenols from phospholipid complexes means that the retention time of polyphenols in vivo is extended, thereby increasing the extent to which they can be absorbed and utilized by the body.

Results show that VC-NLP-0.5% ZnAC has the highest positive surface charge (30.12±1.19 mV) and small diameter (305±4.53 nm), making it the optimal formulation for improving EE and stability of vitamin C.
