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.

Objective: To investigate how pH affects the rate of protein digestion Hypothesis: I predict that since pepsin breaks down the material the quickest at a pH of 2 in the stomach‚ test tubes #3 will reduce the greatest because it has pepsin to further break down the egg. Whereas the other test tubes will have a smaller reduction. I think test tube #2 will have the second largest reduction rate and then #6 because they all will have a greater rate at breaking down the material‚ Then‚ I predict the

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"

generations of these devices is the form-stable cohesive gel implant‚ which is also referred to as ‘gummy bear’ breast implants. Dr. Nina S. Naidu is a board-certified plastic and reconstructive surgeon in Manhattan who frequently performs breast implant surgery using the innovative gummy bear breast implant devices. The Reason Form-Stable Cohesive Gel Implants are Called ’Gummy Bear’ Breast Implants The consistency of the form-stable cohesive gel implant is very similar to that of a piece of gummy

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

Protein powder is bad because it contained a lot of additive‚ sugar and too much protein. Although natural protein provide immune system defense for the body and also contain antioxidant components‚ however‚ that does not mean that protein shake or protein powder has the same function as the natural protein. As time goes by‚ protein powder has become essential for muscle builder to consume. People drink protein shakes or take pills while they are working out or after performing intense exercise.

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‚

BENEFITS OF WHEY PROTEIN IN FITNESS For centuries people have been using whey proteins for their beneficial health properties. Whey is derived from milk and is the by product of cheese production. Today it has found its place in nutrition as it offers optimal health and enables good fat burning. It is a low fat‚ low calorie and low carbohydrate food that is placed low on the glycemic index (GI) Scale. Replacing high fat and high calorie meals with this protein will melt the fat away because the

Relationships of Proteins Proteins are a group of organic compounds whose molecules consist of carbon‚ hydrogen‚ oxygen‚ nitrogen and sometimes sulfur atoms. They are condensation polymers of amino acids that are joined by strong peptide bonds. There are 20 different types of amino acids available‚ and the different combinations of these amino acids give it different structures and specific functions to it. Below in this essay‚ will illustrate the how different structure of a protein is related to

To purify the protein in the cell lysate from lab 1 through nickel affinity chromatography. Protein purification should result in only one type of protein ideally‚ which is the protein of interest‚ wt-DHFR and mut-DHFR in this case. A pure protein allows for further analysis on the protein to be conducted‚ such as its concentration (Bradford assay)‚ its molecular weight‚ and its biological activity. 2.
