The lipid-rich stratum corneum functions as a barrier against pathogens and desiccation inter alia by an unbroken meshwork of extracellular lipid lamellae. These lamellae are composed of cholesterol, fatty acids, and ceramides (Cers) in an equimolar ratio. The huge class of skin Cers consists of ...

Fungi are organisms composed of masses of tubes or filaments, called hyphae. Fungi do not produce their own food like plants. They need to get their food from their surroundings. They get their food by hiding the digestive enzymes or proteins to dissolve organic and inorganic food materials.…...
Its crystal structure is responsible for the extraordinary lubricity molybdenum dioxidide. Its molecules are composed of weakly bonded lamellae. Extreme pressure cannot squeeze the lamellae out, and the coefficient is only 0.025. It is very rare to be exposed to molybdenum diulfide in the workplace...
Lamin proteins are type V intermediate filament proteins (IFs) located inside the cell nucleus. They are evolutionarily conserved and have similar domain organization and properties to cytoplasmic IFs. Lamins provide a skeletal network for chromatin, the
