Ascorbato ridotto

Descrizione:

Ascorbato ridotto, comunemente noto come acido ascorbico o vitamina C nella sua forma ridotta, è una vitamina solubile in acqua e antiossidante. Svolge un ruolo cruciale in vari processi biologici, inclusa la sintesi del collagene, la funzione immunitaria e l'assorbimento del ferro dagli alimenti vegetali. La struttura chimica di Ascorbato ridotto presenta un anello di lattone a sei carboni con più gruppi idrossile, che contribuiscono alla sua reattività e solubilità in acqua. Come antiossidante, aiuta a neutralizzare i radicali liberi, proteggendo così le cellule dallo stress ossidativo. Ascorbato ridotto è anche coinvolto in reazioni enzimatiche, fungendo da cofattore per diversi enzimi importanti. È generalmente stabile in condizioni acide, ma può degradarsi in presenza di calore, luce e ossigeno. Nelle fonti alimentari, si trova abbondantemente in frutta e verdura, in particolare in agrumi, bacche e verdure a foglia. A causa del suo ruolo essenziale nella salute umana, Ascorbato ridotto è spesso incluso in integratori alimentari e alimenti fortificati.

L-Gulonic acid-1,4-lactone

CAS: 1128-23-0

L-Gulonic acid-1,4-lactone is an ascorbic acid derivative that inhibits the production of matrix metalloproteinases (MMPs) and other enzymes. L-Gulonic acid-1,4-lactone has been shown to inhibit the activity of MMPs in hl-60 cells, which may be due to its ability to chelate metal ions, such as zinc and copper. This molecule also has a stabilizing effect on collagen type I because it prevents cross linking between lysine amino acids. The discovery process for this molecule was found by screening clones from a cDNA library with biochemical properties similar to those of ascorbic acid. This molecule has been shown to inhibit the activation of protein kinase C (PKC) and phosphorylation of extracellular signal regulated kinase (ERK). L-Gulonic acid-1,4-lactone is metabolized through plant metabolism

L-Gulono-γ-lactone

CAS: 1128-23-0

L-Gulono-gamma-lactone is a natural vitamin C metabolite that is synthesized from L-ascorbic acid in the liver. It has been shown to inhibit the oxidase and other enzymes involved in ascorbic acid metabolism, which may be due to its ability to bind to iron. L-Gulono-gamma-lactone also inhibits polymerase chain reactions in rat liver microsomes and inhibits the activities of ascorbic acid and glutathione reductase in rat hepatic tissues. This compound is not active against humans, but it has been shown to have antioxidation properties.
