    If pH > pI‚ then the protein will have a negative charge and if pH < pI‚ the protein will have a positive charge. Buffer I has a pH >5‚ meaning both proteins carry a negative charge and bind to the DEAE (a positively charged resin). (b) pH = pKa + log10(Base/Acid) [Base = mM of sodium acetate; Acid = mM of acetic acid] = 4.7 + log10 (40/40) = 4.7 In order for the catalase to elute from the column‚ it must have lost its negative charge and stopped binding to the DEAE. Lowering the pH

    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"

    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
