to pass in and out. This exchange is controlled by blood pressure through hydrostatic pressure and osmotic pressure. Osmotic pressure is produced by high levels and salts and proteins in the blood. As blood enters the capillary by the arteriole end the blood pressure is higher than the osmotic pressure. When it reaches the middle of the capillary the blood of the vessels equals out to the pressure of the osmotic pressure. At this point the gases and nutrients exchange at this point. Once it reaches

DENATURATION OF PROTEINS Abstract The experiment was done to be able to understand how various denaturants such as HCl and NaOH affects proteins. It was observed that different denaturants act upon or denature protein differently. This was determined using the principle of viscometry. An Ostwald viscometer was used to measure the viscosity of the prepared native‚ blank‚ denatured native and blank with denaturant solutions. The time required for the said solutions to pass through the viscometer

Sleep is food for are Brain. Just like your body‚ we need the right food to help develop and support are growing body. Are Brains go through a process every time we sleep called memory consolidation. What this does is‚ When we are sleeping are brains go through everything that happened throughout our day and makes them long-term memories. If we aren’t sleeping well are brains can’t make this process happen‚ which can cause memory loss. Without Sleep (Brain Food) are brains won’t be able to function

4A.2 RRL 4A.2.1 Coagulation of Proteins Coagulation of protein refers to sticking together‚ like a blood clot‚ usually as a result of denaturation or coming out of solution due to abnormal ionic strength or a change of solvent. Definite characteristics of the proteins are changed when they are coagulated‚ among which is loss of solubility in water and dilute salt solutions. In some instances and under certain conditions the coagulation process may be reversible. (Campbell‚ et.al‚ 1979) 4A.2.2

Proteins are polymeric chains that are built from monomers called amino acids. All structural and functional properties of proteins derive from the chemical properties of the polypeptide chain. There are four levels of protein structural organization: primary‚ secondary‚ tertiary‚ and quaternary. Primary structure is defined as the linear sequence of amino acids in a polypeptide chain. The secondary structure refers to certain regular geometric figures of the chain. Tertiary structure results from

Why Friendship Important As is rightly said‚ “A friend in need is a friend indeed”. Friends are an important part of every individual’s life. You talk with them about every damn thing; share your top secrets and what not. You enjoy with them and spending time with friends is fun always.

So‚ friends are truly important. They sometimes

Introduction “Nutrition is the science that deals with foods and the way our body uses them”(McKim 1997). When thinking about proper nutrition and the way we live our life’s‚ many believe that going to the gym or not eating fast food is enough to stay healthy. Although doing both is very important‚ overall the best thing you can do to stay healthy is having the proper amounts of vitamins and minerals your body needs in a given day. When given this assignment many thoughts ran through my mind about

living creatures‚ work together in a certain process that is crucial to existence: the formation of proteins. Although all species differ from each other in various ways‚ the processes by which proteins are synthesized are the same in all. Protein synthesis is a very complex process. In order to understand the process‚ there some basics that are essential for cells to create the proper proteins. DNA is a very long and double-stranded molecule that contains coding‚ through four nitrogen bases (adenine
