    Background: Pepsinogen is an inactive protein that is the mucus lining of the stomach. When converted to pepsin‚ the enzyme is used to break down large or undigested protein they has been absorbed by the small intestine. The digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). In the intestine the gastric acids are neutralized (pH 7)‚ and pepsin is no longer effective.

    It makes sense to think that quick‚ post-workout protein intake might boost recovery and promote higher performances on subsequent days of training. Indeed‚ some research has suggested that protein intake can help athletes adapt to their workouts more effectively. However‚ such studies have been flawed methodologically‚ and a new investigation reveals that combining protein with carbohydrate after workouts is not a superior strategy‚ compared with taking carbs alone. You’ve heard them: The "experts"

    G-protein Coupled Receptors (GPCRs) are cell surface proteins that relay extracellular signals to the nucleus. These signals can be in the form of light‚ peptides‚ lipids‚ and sugars. Once activated by a ligand at the outer cell surface‚ GPCRs activate their cognate G-proteins that reside on the inner cell membrane. The activated G-proteins then slide along the inside of the cell membrane to activate a cascade of proteins and enzymes that in turn amplify the original message received by the GPCR

    glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and oxygen that are within the mesophyll layer of the leaves. But in order to measure the rate of photosynthesis‚ the gases in the leaves need to be drawn out of the mesophyll. This can be done by creating a vacuum‚ which will further be explained in the procedure. This will allow us to see the effect of one reactant‚ carbon dioxide

    The first half of module seven discussed protein digestion‚ absorption‚ and metabolism; while the second half focused on pathological stress and kidney disease. Protein digestion occurs in the stomach and small intestine. When a protein reaches the stomach it is denatured by hydrochloric acid. Once the protein is digested pepsin breaks apart the denatured protein into peptides. Peptides move into the small intestine where they encounter an enzyme that digest the peptides into di- or tripeptides‚

    Abstract There are many methods employed to precipitate proteins out of solution. In this experiment we manipulated many physical and chemical variables in order to achieve purification of a protein via precipitation. In the first part of the experiment we purified the protein casein by modifying it’s pH. In the second part of the experiment we manipulated the ionic strength of albumin in egg whites‚ in a process called salting out. By manipulating these chemical properties we were able to
