Lactic acid, D- is a natural optical isomer of lactic acid. It is a poorly utilized isomer – 30 to 40% of the dose ingested is excreted in the urine. Lactic acid, D- is known to be harmful to human metabolism and it can result in acidosis and decalcification. D-lactic acidosis, also referred as D-lactate encephalopathy, has been reported in patients with short bowl syndrome. Lactic acid, D- is an interesting precursor for manufacturing heat-resistant polylactic acid (PLA) bioplastics which can be widely used, for example as packaging material, coatings, for textiles or in the automotive industry.

D,L-Glutamic acid is a mixture of naturally occurring proteinogenic L-glutamic acid and non-proteinogenic D-glutamic acid. D,L-Glutamic acid is used to study mechanisms of crystal formation and self-assembly on surfaces and copolymer development. D-Glutamic acid is a component of bacterial peptidoglycans, produced by glutamate racemase.

Diaminohydroxypropane tetraacetic acid is a chelating agent for various metals including Fe, Mn, Tc and lanthanides.

Oxothiazolidinecarboxylic Acid (L-2-oxothiazolidine-4-carboxylic acid, OTC) was currently undergoing evaluation in a Phase II clinical trial. It is suggested that an ideal drug may be an antisense oligonucleotide that blocks the expression of glycolate oxidase, a key enzyme in hepatic oxalate synthesis.
