For initiation of the translation process, the ribosome binds to the mRNA at the start codon recognized by the initiator tRNA. The ribosome then proceeds to the elongation phase of protein synthesis. During this stage, the complexes formed by amino acids are linked to tRNA, sub sequentially to bind to the appropriate codon in mRNA by forming complimentary base pairs with the tRNA anticodon. The ribosome moves from codon to codon along the mRNA. Amino acids are added one by one, translated into polypeptide sequences dictated by the DNA and represented by mRNA. At the end, release factor binds to the stop codon, thus terminating the translation stage and completing the protein synthesis process. The complete polypeptide is released from the .
The process of polymerization of amino acids to form a polypeptide is called as Translation. It is the second and final step of protein synthesis. The order into which the amino acids are arranged is defined by the bases in mRNA (messenger). Ribosome is the cellular factory responsible for the protein synthesis. The ribosome consists of structural RNAs and about 80 different . It is in inactive stage and exists as two subunits, one large and other small. The synthesis of begins when the small subunit encounters an mRNA. The ribosome also acts as a catalyst for the formation of bonds.

Protein is a large complex molecule that must undergo a series of processes during digestion. During digestion and absorption, protein passes through many organs. Once protein is digested, the body can utilize its nutrients to build and repair many of the cells in the body. The body also uses the calories from protein which is released during the digestion process for energy, when carbohydrates and fats are not available. The protein subjected to digestion and absorption are obtained from two sources: Exogenous and endogenous. Whole proteins are not absorbed; they are too large to pass through cell membrane. Digestive enzymes like hydrolases break the peptide bond of protein and secreted as inactive pre-enzymes. Some seven or more factors influence how fast the enzyme act on the proteins. These factors includes the concentration of the enzymes i.e. how much of it is present; the amount of the protein feed needing action, the acidity of the food and stomach, the temperature of the food, time and the presence of any digestive inhibitors such as antacids.

Thus, hemoglobin's biological function is regulated by thechanging of the overall protein structure. This structure isaltered by the binding or releasing of CO2 and H+to the interfaces of the subunits in hemoglobin (Figure 8).

Once food is chewed and swallowed, HCl and pepsin begin protein digestion in the stomach. HCl helps to kill bacteria in food that could cause infection and breaking the bond between the proteins which are disintegrated into amino acid and plays an important role in metabolism. It also makes the stomach very acidic with a pH of 1.5. This acidic environment is necessary for HCl to react with pepsinogen to form pepsin so that it can break the central peptide bond in proteins. Renin is an enzyme i.e. present in infants to help breakdown milk protein.
