Lactic Acid | Community Health

Lactic acid is an organic acid with the molecular formula C3H6O3, known for its role in various biochemical processes, industrial applications, and human health. It is an alpha-hydroxy acid (AHA) and a synthetic intermediate in many organic synthesis industries. Lactic acid is produced through both artificial synthesis and natural sources, including fermentation by [[lactobacillus|Lactobacillus]] bacteria. Its conjugate base, lactate, plays a crucial role in energy production and is a key component of [[cellular-respiration|cellular respiration]]. With a pKa value of 3.86, lactic acid is ten times more acidic than [[acetic-acid|acetic acid]], making it a valuable compound in various industries, including food, pharmaceuticals, and cosmetics. The global lactic acid market is projected to reach $1.6 billion by 2025, driven by increasing demand for biodegradable plastics, [[probiotics|probiotics]], and [[personal-care-products|personal care products]]. As research continues to uncover the benefits and applications of lactic acid, its significance in human health and industry is expected to grow, with potential applications in [[cancer-treatment|cancer treatment]], [[wound-healing|wound healing]], and [[sports-nutrition|sports nutrition]].
