一般描述

碳酸钠（纯碱）是一种无机化合物。它用于化学品的合成、洗涤剂配方、烟气脱硫以及造纸和纸浆生产。

应用

碳酸钠可用于：
  • 作为催化剂,用于合成查尔酮和扎查尔酮时醛和酮的羟醛缩合反应。
  • 作为pH稳定剂，用于在柠檬香茅作为还原剂参与时合成FeO-NPs（氧化铁纳米颗粒）。
  • 作为碱，用于Pd催化的铃木偶联反应。
  • 作为碱，用于无过渡金属参与的铃木偶联反应，该反应使用水作溶剂且TBAB（四丁基溴化铵）作相转移催化剂催化芳基卤化物和芳基硼酸反应生成联芳基。

生化/生理作用

缓冲液成分，可用于去除外周膜蛋白。

It has been demonstrated that wine and other products derived from the grape have a high antioxidant capability; as a possible consequence of this, they may have potential benefits for health. The byproducts of the winemaking process represent a source

At present, the circulating bioactivity of insulin-like growth factor I (IGF-I) is estimated by immunological measurements of IGF-I levels. However, immunoassays ignore the modifying effects of the IGF-binding proteins (IGFBPs) on the interaction between IGF-I and the IGF-I receptor (IGF-IR).

Trousseau described spontaneous, recurrent superficial migratory thrombophlebitis associated with occult cancers, and this was later correlated with disseminated microangiopathy (platelet-rich clots in small blood vessels). Trousseau syndrome often occurs with mucinous adenocarcinomas, which secrete abnormally glycosylated mucins and mucin fragments

The accumulation of RCY1 protein, which is encoded by RESISTANCE TO CMV(Y) (RCY1), a CC-NB-LRR class R-gene, is tightly correlated with the strength of the resistance to a yellow strain of Cucumber mosaic virus [CMV(Y)] in Arabidopsis thaliana. In order
