Membrane-Attack Complex (MAC)

Science / Biology / Membrane-Attack Complex (MAC): A large cylindrical multiprotein complex formed by the complement system; kills invading microorganisms by embedding in their plasma membrane, creating a pore through which fiuid fiows, ultimately causing the cell to burst.

Low Spin Complex

Science / Chemistry / Low Spin Complex: A metal-ligand complex with fewer unpaired electrons than the uncomplexed metal ion. When a strong ligand complexes the metal ion, the crystal field splitting is large and some electrons pair rather t MORE

High Spin Complex

Science / Chemistry / High Spin Complex: A metal-ligand complex with the same number of unpaired electrons as the uncomplexed metal ion. When a weak ligand complexes the metal ion, the crystal field splitting is small and the electrons can s MORE

Golgi Complex

Science / Biology / Golgi Complex: Organelles in animal cells composed of a series of fiattened sacs that sort, chemically modify, and package proteins produced on the rough endoplasmic reticulum. MORE

Media Access Control (MAC) Address

Technology / Computers / Media Access Control (MAC) Address: In networking, MAC Address refers to the globally unique hardware address of an Ethernet network interface card. MORE

Membrane-Attack Complex (MAC)
