Pre-treatment for heat tolerance enhancement of the Indian almond (Pithecellobium dulce) seedlings using ascorbic acid and potassium chloride

Folia Oecologica, 2023
In light of global warming, pre-treatment plants with antioxidants may reduce the damage caused by climatic changes. Indian almond seedlings were planted in pots subjected to ascorbic acid and potassium chloride alone or combined to reduce the negative ...

Studies on L-Ascorbic Acid Derivatives. III. Bis (L-ascorbic acid-3, 3') phosphate and L-Ascorbic Acid 2-Phosphate

Chemical and Pharmaceutical Bulletin, 1969
Phosphorylation of 5, 6-isopropylidene-L-ascorbic acid (I) in acetone with phosphoryl chloride gave, in addition to L-ascorbic acid 3-phosphate (II) and 3-pyrophosphate (III), the following two derivatives, i.e., bis (L-ascorbic acid-3, 3') phosphate (IV) and L-ascorbic acid 2-phosphate (V). The structure of these phosphates was determined on the basis

Nanoamphizymes: Self‐Assembled Amphiphilic Enzymatic Nanomaterials for High‐Performance Biocatalysis and Biosensing

Advanced Functional Materials, EarlyView.
An amphiphilic GOx nanoamphizyme was constructed by covalently introducing hydrophobic PPNI linkers onto GOx, enabling spontaneous self‐assembly into tunable nanoparticles. Mild crosslinking further stabilized the assemblies and enhanced catalytic performance and stability.

Spatially Controlled Embedded Bioprinting of Prevascularized Spheroids‐Containing Biopatch Enables Functional Skin Regeneration

Advanced Healthcare Materials, EarlyView.
A spatially controlled embedded bioprinting strategy enables precise engineering of prevascularized multicellular spheroids within skin‐derived dECM bioinks. Optimized spheroid size, composition, and spacing promote vascular maturation, paracrine signaling, and tissue integration, resulting in enhanced angiogenesis, blood perfusion, and functional skin

Transport model of the human Na+-coupled L-ascorbic acid (vitamin C) transporter SVCT1

, 2008
Vitamin C (L-ascorbic acid) is an essential micronutrient that serves as an antioxidant and as a cofactor in many enzymatic reactions. Intestinal absorption and renal reabsorption of the vitamin is mediated by the epithelial apical L-ascorbic acid ...
