Protostellar streamers are elongated structures that channel material from larger scale onto disks, influencing their physical and chemical evolution. The M512 protostar in Orion/Lynds 1641 hosts one of the most massive and extended streamer discovered so far, offering a unique opportunity to study these processes. We investigated the morphology, chemistry, and origin of this streamer, along with its potential impact on the protostellar disk. Using archival ALMA observations of C 18 O, DCO^+$, N
