Hüdroksüdikarboksüülhape

Hüdroksüdikarboksüülhape is a broad term encompassing organic compounds that contain both a hydroxyl group (-OH) and a carboxyl group (-COOH) within their molecular structure. These functional groups impart distinct chemical properties, making hydroxydicarboxylic acids versatile in various chemical reactions and applications. The relative positions of these groups on the carbon chain significantly influence the compound's reactivity and physical properties.

A common example of a hydroxydicarboxylic acid is malic acid, which is naturally found in fruits like apples and plays a role in the citric acid cycle. Another well-known example is lactic acid, produced during the fermentation of sugars and used in the food and cosmetic industries. Citric acid, despite having three carboxyl groups, also features a hydroxyl group, classifying it within this broader category.

These compounds often exhibit amphoteric behavior due to the presence of both acidic carboxyl groups and weakly basic hydroxyl groups. They can participate in esterification reactions with alcohols and can be oxidized or reduced depending on the specific structure and reaction conditions. In industry, hydroxydicarboxylic acids are utilized as acidulants, chelating agents, and building blocks for polymers. Their biocompatibility and biodegradability also make them attractive for applications in pharmaceuticals and biodegradable plastics.
