The word "Eleidin" refers to a protein found in the stratum corneum of the skin. It is spelled with the phonetic sequence /ɛˈleɪdɪn/, as pronounced in standard American English. The initial "E" is pronounced as the short "e" vowel sound, while the following "l" is a voiceless consonant. The "ei" diphthong is pronounced as a long "a" sound, followed by the voiced dental consonant "d" and the short "i" vowel sound. The final "n" is a voiceless consonant.
Eleidin refers to a substance that is primarily found in the outermost layer of the epidermis, known as the stratum lucidum. It is a translucent protein-like material that is derived from the degradation of keratohyalin granules. Unlike other proteins in the skin, eleidin lacks nuclei and organelles, making it an anucleate material. This lack of nuclei is attributed to the fact that eleidin represents a transitional stage in the formation of keratin.
The main function of eleidin is to maintain the integrity and structural stability of the skin. It contributes to the strength and resistance of the epidermal layer against external factors, such as mechanical stress or UV radiation. Additionally, eleidin acts as a protective barrier, preventing the loss of water from the skin and playing a role in its moisture retention.
Eleidin is typically found in areas of the body that are heavily exposed to wear and tear, such as the palms of the hands and soles of the feet. It is of particular importance in these regions due to the constant friction and pressure they are subjected to, which necessitates added strength and durability in the skin.
In summary, eleidin is a protein-like material found in the stratum lucidum of the epidermis, responsible for maintaining the structural integrity of the skin and acting as a protective barrier against external factors. Its anucleate nature makes it a critical component in areas of the body subjected to increased wear and tear.
A deeply staining substance (possibly hyalin) forming the granules of the stratum granulosum of the epidermis.

The word "eleidin" is a term derived from the Greek language. It comes from the Greek word "ελειδίνη" (eleidini), which itself is derived from the Greek word "ελαία" (elaia) meaning "olive tree". Eleidin is a protein found in the skin, specifically in the stratum granulosum layer, and it helps to waterproof the skin. The term was coined in the early 20th century when scientists discovered and named the protein.
