DL-Serine is widely used in cell culture media as a nutritional supplement for mammalian cells, supporting protein synthesis and cell growth. It serves as a precursor for the synthesis of other amino acids, such as glycine and cysteine, and plays a role in the production of phospholipids, essential components of cell membranes. In neuroscience research, serine is studied for its role as a co-agonist at the NMDA receptor, influencing synaptic plasticity and cognitive function. It has also been explored in clinical studies for potential benefits in neurological disorders, including schizophrenia and certain motor neuron diseases. Additionally, DL-serine is used in pharmaceutical formulations and as a building block in the synthesis of peptides and specialty chemicals.
