Protein Essay- Erin Keegan What are proteins? A polypeptide is a chain of monomers joined up to make a polymer. Proteins are organic polypeptides made up of a chain of amino acid residues- they’re residues because they lose a water molecule. The amino acids (monomers) join up by forming peptide bonds. When two amino acids join together‚ they become a dipeptide. This happens when the carboxyl group of an amino acid and the amino group of another amino acid link up through a condensation reaction (which

The protein in consumed food turns into amino acid. The amino acid is used later replinish the proteins used. Proteins have two structures. the first and primary structure of protein is the sequence of the amino acid in the protein (Kim‚ 2005). The amino acid

Time once again went by and

Introduction Protein purification is the series of processes to isolate a single type of protein from a complex mixture. This is vital to extract and characterize the protein of interest. However‚ before doing so‚ it is important to release the protein from the subcellular organelles. This step is also known as homogenization. This step can be done with the use of blender. As the solution was homogenized‚ it may undergo saltation or acidation to remove impurities such as calcium anions. Hexane
