Human skin appears very different from that of animals. Think of an elephant’s skin and then take a look at yours. They are as different as chalk and cheese, isn’t it? Even all animals do not have the same texture of skin. But, they have one thing in common; both human and animal skin is made of a protein called collagen.
Collagen has a fibre-like structure. It forms an elastic layer below the skin which makes it smooth and supple. Collagen present in animal skin can be made into leather by a process called tanning during which, the skin will be cross linked. This modification makes it strong and durable.
