Keratin is a protein, while keratinocytes are the cells that produce and secrete keratin. Keratinocytes make up the majority of cells in the epidermis, the outermost layer of skin. Keratin is an essential component of skin, hair, and nails, providing strength and structure to these tissues.
Here's a simple breakdown:
- Keratinocyte: A type of cell found in the epidermis. It produces keratin.
- Keratin: A protein produced by keratinocytes. It forms the structural framework of skin, hair, and nails.
Think of it like this: A baker (keratinocyte) makes bread (keratin). The baker creates the bread, while the bread itself is a distinct product.
Key Points:
- Keratinocytes are responsible for the production of keratin.
- Keratin provides strength and structural integrity to skin, hair, and nails.
- Different types of keratin exist, each with unique properties.
