产品描述

General description

L-ascorbic acid is used as a food additive, browning inhibitor, flavor stabilizer, dough modifier and color stabilizer. Deficiency of ascorbic acid is associated with scurvy. L-ascorbic acid stimulates immune response and is implicated in the synthesis of collagen, carnitine and neurotransmitters.[1]

Application

L-Ascorbic acid has been used:
• as a component in osteogenic differentiation medium[2]
• in MesenCult medium for the differentiation of bone marrow stromal cells[3]
• as a standard for vitamin C assay[4]
• to prevent trihalomethanes formation potential (THMFP)[5]

包装

2 kg in poly drum

25, 100, 500 g in poly bottle

Biochem/physiol Actions

L-Ascorbic acid (L-AA) is a widely available and water-soluble compound. L-AA has an ability to inhibit the corrosion of mild steel.[6]

抗坏血酸,也称为维生素C,是由植物和一些动物物种产生的六碳内酯,但人类和其他灵长类动物不能产生。抗坏血酸作为多种酶的酶促辅助因子发挥作用,用作单加氧酶和双加氧酶的电子供体。抗坏血酸也是一种强大的抗氧化剂,尤其是对活性氧类。
