THE PROTEINS Proteins are molecules made of amino acids. They are coded for by our genes and form the basis of living tissues. They also play a central role in biological processes. For example, proteins catalyse reactions in our bodies, transport molecules such as oxygen, keep us healthy as part of the immune system and transmit messages from cell to cell. Protein synthesis A gene is a segment of a DNA  molecule that contains the instructions needed to make a unique protein. All of our cells contain the same DNA molecules, but each cell uses a different combination of genes to build the particular proteins it needs to perform its specialised functions. Protein synthesis has 2 main stages. The 1st stage is known as transcription, where a messenger molecule (mRNA) is formed. This molecule is transcribed from the DNA molecule and carries a copy of the information needed to make a protein. In the 2nd stage, the mRNA molecule leaves the nucleus for the cytoplasm where t...

 As much as eating and feeding is essential for living , it is important to eat well or feedwell . What we eat is as important  as how we eat. so, strike thE balance between "what we eat" and "how we eat" is crucial . Strike the balance is to a balance diet. We need food, water ,shelter as human . Yes , not all food, water are beneficial for growth and healthy living. Likewise ,not all environment are safe .        A good food must give or supplement  the bodywith vitamin ,mineral,protein, carbohydrates e.t.c. but with percentage needed in the body because their excess in the body canbe dangerous. This is called striking the balance in feeding.         Therefore,it is expedient to consider each categories of food as regards their contents and end products in related to the impact on the body system. There are many health problems  that could arise from inordinate consumption of food and water . e.g Obesity, diabetes, cafd...

What exactly is protein? Think of protein as strings of sausages. Long strings – some many thousands.  Each sausage represents one of 15 similar small molecules called amino acids. The order of amino acids in the chain is programmed by DNA.  “Amino” means that they contain nitrogen, but they also contain carbon, hydrogen and oxygen atoms.  In order to do their jobs, proteins curl up into characteristic shapes, and many of them need to incorporate minerals or vitamins in order to function. Some proteins are solid, some are flexible in cell membranes, others are mobile in solutions.  when we eat proteinous food; The cells in your intestine can’t absorb whole proteins, only single amino acids or very small chains of two or three amino acids – called peptides.  So digestive enzymes (specialised proteins themselves!) break down the proteins into their component amino acids – essentially, cutting the string between the sausages. The amino acids and ...
