Definition: The Greek word for "antiheterolysin" is "alpha-keratin". In its scientific name, it corresponds to the term in biology used for the proteins found on the surface of keratinocytes. This protein plays a crucial role in the skin's protective barrier by binding water and other substances that are important for cell function. Alpha-keratin can also be referred to as "alpha-vitamin A" or "vitamin A 7". It is essential for maintaining healthy hair, skin and nails by protecting them from damage caused by UV rays. This word has many medical applications in dermatology, where it's used in the diagnosis of certain conditions such as psoriasis and eczema. Alpha-keratin also serves as an antioxidant that helps protect against free radicals, a type of stress hormone that can contribute to skin aging and some cancers.
