Chemistry:Hydroxycarboxylic acid
From HandWiki
Hydroxycarboxylic acids are carboxylic acids containing one or more hydroxy (alcohol) functional groups. They are of particular interest because several are bioactive and some are useful precursors to polyesters. The inventory is large.[1]
Important or common examples
- Glycolic acid, CH
2(OH)CO
2H, precursor to laquers - Hydroxypropionic acids, e.g., CH
3CH
2(OH)CO
2H (lactic acid), component of milk - Hydroxybutyric acids, CH
3CH(OH)CH
2CO
2H (beta-Hydroxybutyric acid), carbon-storage compound - Citric acid, HO

2, energy-carrying compound and iron-chelator - Salicylic acid, 2–HOC
6H
4CO
2H, precursor to aspirin - Ricinoleic acid (12-hydroxy-9-cis-octadecenoic acid)), a major component of the seed oil obtained from castor plant
- Tyrosine, 4–HOC
6H
4CH
2CH(NH
2)CO
2H, a common amino acid
Subclasses
Classes of hydroxycarboxylic acid are named by where the hydroxy group is on the carbon chain relative to the carboxylic group.
