A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using a single line of chemical element symbols and numbers. Apr 03, · In this experiment, we have to investigate about the protein contents (concentration) in the five egg’s samples which are telur ayam biasa, ayam kampung, ayam omega, puyuh and itik. We used Biuret reagent test to test the content of protein in all those egg grupobittia.com: group 4 biochem. 2. ESSENTIAL NUTRIENTS - PROTEINS AND AMINO ACIDS Proteins. The proteins are among the most important constituents of all living cells and represent the largest chemical group in the animal body, with the exception of water; the whole fish carcass contains on average 75% water, 16% protein, 6% lipid, and 3% ash.
