L-(+)-Lactic acid, also known as L-Lactic acid, a stereoisomer of lactic acid, is integral in biochemistry for its diverse molecular roles. In biochemistry L-(+)-Lactic acid is instrumental for conducting both in vitro, providing insights into its influence on cellular activities and the biology of organisms. It′s understood that it engages with cellular proteins and enzymes to help manage critical functions, such as metabolic energy output and cellular proliferation. Lactic acid is also recognized for its capacity to interact with genetic material, potentially guiding gene expression. L-(+)-Lactic acid contributes to the manufacture of various compounds like polylactic acid.
