Chemically finger nails are made up of

A. Carbohydrate
B. Fats
C. protein
D. Starch

Check Answer

The correct answer is C) protein.

Fingernails are primarily composed of a tough, fibrous protein called alpha-keratin. Alpha-keratin is a type of protein that is also found in hair, hooves, horns, claws, and feathers. This protein is produced by specialized cells in the skin called keratinocytes. The keratinocytes produce and release the protein as they move towards the surface of the skin, where it accumulates and hardens to form the nail plate. Carbohydrates, fats, and starch are not significant components of fingernails.
