Aconitate

The author's experiments were performed upon perfectly pure neutral malate of lime, supermalate of lime, malate of potash, aspartate of potash, aspartate of lime, fumarate of lime, maleate of lime, and aconitate of lime extracted from the Aconitum napellus.

The crystals of aconitate of calcium are dissolved by slight acidulation with nitric acid, and precipitated by acetate of lead, and the lead salt decomposed by hydrosulphuric acid.

The enzyme aconitase catalyzes the elimination or addition of water in the second step of the citric acid (Krebs) cycle, catalyzing the interconversion of citrate and isocitrate via cis-aconitate.
