Haemoglobin, Ossein, Myosin, Keratin are all different types of proteins found in different parts of the human body.

Some types of protein:

• Haemoglobin- It is a protein found in the blood. It contains four subunits i.e. alpha and beta subunit. The main function of haemoglobin is to carry oxygen.
• Ossein- It is a protein found in the matrix of bones. It is made up of collagen. It is used to make bone glue.
• Myosin- It is a protein found in skeletal muscles where it converts the chemical energy of ATP into mechanical energy thereby facilitating movement and contraction.
• Keratin- It is a type of fibrous protein, present in hairs, nails, scales. It has protective functions.

Proteins are polymers of small monomeric units of amino acids. Many other proteins are found inside humans like actin, tubulin, etc.
