Descrizione generale

Potassium bicarbonate (Potassium hydrogen carbonate) is an inexpensive, nontoxic base. It is used to regulate pH or as a reagent.

Applicazioni

Potassium bicarbonate is used:
  • In the synthesis of cyclic ammonium cation N,N-dimethyl-3,5-dimethylpiperidinium (DMDMP).
  • As a base in the preparation of glycerol carbonate and glycidol from 3-chloro-1,2-propanediol (HAL).

Chromatin states must be maintained during cell proliferation to uphold cellular identity and genome integrity. Inheritance of histone modifications is central in this process. However, the histone modification landscape is challenged by incorporation of new unmodified histones during each cell

Liquefaction of glucose into oil was examined in hot-compressed water at 300 degrees C and 30 or 60 min in a tumbling batch reactor. The effects of alkali (KHCO(3)), a hydrogenating agent (HCO(2)H), and a cobalt catalyst (Co(3)O(4)) were studied.

Bicarbonate has been implicated in bone health in older subjects on acid-producing diets in short-term studies. The objective of this study was to determine the effects of potassium bicarbonate and its components on changes in bone resorption and calcium excretion

High sodium chloride (NaCl) intake can induce low-grade metabolic acidosis (LGMA) and may thus influence bone and protein metabolism. We hypothesized that oral potassium bicarbonate (KHCO(3)) supplementation may compensate for NaCl-induced, LGMA-associated bone resorption and protein losses. Eight healthy male
