Explain why during an experiment, casein precipitates when hydrochloric acid is added to it
Consider the structures of casein and lactose Your manual states: "Casein is a phosphoprotein, meaning that phosphate groups are attached to the hydroxyl functions of some of the amino acid side-chains." Based on this sentence. provide the name and structure of at least two functional groups that must be present in a. casein b. Lactose is a disaccharide. Provide the name and structure of at least two functional groups that must be present in lactose. You must include the functional...
If you added too much acetic acid to the milk solution , what would happen to the lactose? Please, draw the products of the reaction that would occur. Thank you!
1. When lime is added to an acid soil, explain what it does to 1) soil pH (and what is the mechanism by which it changes the pH); 2) cation exchange capacity (Hint: Think back to pH-dependent charge to understand the effect on cation exchange capacity.) and; 3) the composition of exchangeable cations. 2. Why do some soils need more lime to raise their pH than other soils? Explain your answer in terms of buffering capacity, and active vs. reserve...
