Pronunciation: [sˈɛfɐlˌɪnz] (IPA) 
Cephalins is spelled with a hard 'k' sound at the beginning, represented by [kəˈfælɪnz] in IPA phonetic transcription. This word refers to a class of phospholipids found in the tissues of animals, and is commonly used in medical and biochemical research. The correct spelling of this word is important for accurate communication within these fields. It is derived from the Greek word 'kephalē', meaning "head".
Cephalins is a term used in biochemistry and medicine to refer to a group of phospholipids that are present in various tissues and biological fluids. These phospholipids are characterized by having a head group consisting of serine or ethanolamine, along with varying fatty acid chains.
One of the main functions of cephalins is their involvement in the structure and integrity of cell membranes. They are a prominent component of the lipid bilayer that forms the cell membrane, contributing to its fluidity and stability. Cephalins also participate in various cellular processes, including membrane fusion, receptor signaling, and membrane trafficking.
Furthermore, cephalins are involved in blood clotting mechanisms. Specifically, a subtype called platelet cephalins is an essential component in the formation of blood clots. They play a role in the activation of the coagulation cascade and help regulate the clotting time.
In laboratory settings, cephalins are commonly utilized in diagnostic tests, particularly those focusing on blood clotting disorders. Various assays and tests involve the utilization of cephalin-containing reagents to measure coagulation time, clot formation, or the presence of specific clotting factors.
Overall, cephalins are a group of phospholipids that have significant roles in cellular membrane structure, blood clotting, and diagnostic procedures. Their diverse functions highlight their importance in maintaining normal physiological processes and their potential relevance in various pathological conditions.
The word "cephalins" is derived from the Greek word "kephalē", which means "head". In the context of "cephalins", it refers to the head or the brain. The suffix "-in" is a common ending in chemistry and biology to indicate a substance or a class of substances. Therefore, "cephalins" refers to a class of substances found in the head or brain.
