Mainly the hair and fingernails.
Hair and some other fibers contain keratin.
Fishes of class AGNATHA (myxini) have tooth-like structures that are composed of KERATIN..
Keratins dead tissue, so finger nails, toe nails, horse hooves, horns etc.
keratin
Collagen and keratin are examples of proteins in mammals that primarily exhibit only primary and secondary structures. Collagen is known for its triple helix structure, while keratin is a fibrous protein that forms alpha-helices and beta-sheets.
Yes, it's called "Keratin".
Keratin being insoluble helps provide structural strength and rigidity to cells and tissues where it is found, such as in hair, nails, and skin. This insolubility ensures that keratin can maintain its shape and function effectively in these structures.
They are all made of keratin.
The fibrous protein responsible for the structure of hair and wool is keratin. Keratin is a key structural protein in hair, nails, feathers, and horns, providing strength and resilience to these structures.
Yes, hair contains a protein called keratin.
They contain some keratin, but not a whole lot, like the rest of your skin.
Actually, finger nails contain protein (called "keratin").
