Oksalaattiryhmän

Oksalaattiryhmän refers to a group of chemical compounds that contain the oxalate anion. The oxalate anion has the chemical formula C2O4^2-. It is derived from oxalic acid, which is a dicarboxylic acid. Oxalate is a common substance found in many plants, including leafy greens like spinach and rhubarb, as well as in some fruits and nuts.

In chemistry, oxalates can form salts with various metal cations, such as calcium, sodium, potassium, and magnesium. For example, calcium oxalate is a common mineral and is also found in the human body. It is a primary component of certain types of kidney stones. The solubility of oxalate salts varies greatly depending on the cation. Calcium oxalate, for instance, is poorly soluble, while sodium oxalate is highly soluble in water.

The presence of oxalates in the diet is a topic of interest due to their potential health effects. High intake of oxalates can interfere with the absorption of certain minerals, particularly calcium. For individuals prone to kidney stones, particularly those composed of calcium oxalate, dietary recommendations often include limiting the consumption of high-oxalate foods. However, for most people, oxalates consumed from food are not a significant health concern. Oxalates also play roles in various industrial processes and are used in some cleaning agents and rust removers.
