3- Hydroxypropionic acid three-carbon

Hydroxypropionic Acid (3-HPA). Like the structurally isomeric lactic acid, 3-HPA constitutes a three-carbon building block with the potential of becoming a key intermediate for a variety of high-volume chemicals malonic and acrylic acids, methacrylate, acrylonitrile, 1,3-propanediol, and so forth.Thus, Cargill is developing a low-cost fermentation route by metabolic engineering of the microbial... 

Lactic Acid, CH3.CHOH.COOH, a-hydroxypropionic acid, exists in three forms, two of which are optically active. The acid contains an asymmetric carbon atom and its optical activity is traced to this cause as in the case of amyl alcohol, which has been considered at some length (77). 

Hydroxypropionic acid (3-HP), which is also called hydracrylic acid or ethylene lactic acid, is a three-carbon nonchiral organic acid. Two functional groups (carboxyl and P-hydroxyl) provide 3-HP with high reactivity, and as a result, 3-HP is a promising chemical precursor for polymer materials and other chemical feedstocks.
