The organic compounds that make up the blood protein include serum albumin -55%, globulins -38%, and fibrinogen-7%. The remaining compounds that make up 1% plasma proteins are regulatory proteins such as enzymes, proenzymes, and hormones.

So, the correct answer is ' Albumins, globulins and prothrombin'
