Acids for Laboratory, Analysis, and Regulated Applications

Application

Lactic acid is used as a reagent in organic synthesis (in the manufacture of adhesives). It is used in the leather, textile, and tanning industries. It may be used as a plasticizer, a catalyst, or an acidifying agent. Lactic acid has even been used as a flavoring agent in the manufacture of tobacco products.

Biochem/physiol Actions

In animals, lactic acid is a metabolic compound produced by proliferating cells and during anaerobic conditions such as strenuous exercise. Lactic acid can be oxidized back to pyruvate or converted to glucose via gluconeogenesis. Lactic acid is preferentially metabolized by neurons in several mammal species and during early brain development.

Preparation Note

This product is miscible with water (10% v/v).

Recent advances in lactic acid production by microbial fermentation processes.

Mohamed Ali Abdel-Rahman et al.

Biotechnology advances, 31(6), 877-902 (2013-04-30)

Fermentative production of optically pure lactic acid has roused interest among researchers in recent years due to its high potential for applications in a wide range of fields. More specifically, the sharp increase in manufacturing of biodegradable polylactic acid (PLA)

Cancer-generated lactic acid: a regulatory, immunosuppressive metabolite?

Stephen Yiu Chuen Choi et al.

The Journal of pathology, 230(4), 350-355 (2013-06-05)

The common preference of cancers for lactic acid-generating metabolic energy pathways has led to proposals that their reprogrammed metabolism confers growth advantages such as decreased susceptibility to hypoxic stress. Recent observations, however, suggest that it generates a novel way for

Comparison of biochemical stress indicators in juvenile captive estuarine crocodiles (Crocodylus porosus) following physical restraint or chemical restraint by midazolam injection.

Annabelle Olsson et al.

Journal of wildlife diseases, 49(3), 560-567 (2013-06-20)

Using a prospective, randomized study design we demonstrate that midazolam sedation minimizes acidosis compared with physical restraint in captive juvenile estuarine crocodiles during handling or noninvasive procedures at preferred body temperature. A dose of midazolam (5.0 mg/kg) was administered intramuscularly

Exploitation of vegetables and fruits through lactic acid fermentation.

Raffaella Di Cagno et al.

Food microbiology, 33(1), 1-10 (2012-11-06)

Lactic acid fermentation represents the easiest and the most suitable way for increasing the daily consumption of fresh-like vegetables and fruits. Literature data are accumulating, and this review aims at describing the main features of the lactic acid bacteria to

Performance of point-of-care diagnostics for glucose, lactate, and hemoglobin in the management of severe malaria in a resource-constrained hospital in Uganda.

Michael Hawkes et al.

The American journal of tropical medicine and hygiene, 90(4), 605-608 (2014-03-05)

Severe malaria is frequently managed without access to laboratory testing. We report on the performance of point-of-care tests used to guide the management of a cohort of 179 children with severe malaria in a resource-limited Ugandan hospital. Correlation coefficients between
