Let's look at each of these in turn: 1  Whey protein concentrate-WPC contains low levels of fat and low levels of carbohydrates (lactose). 2  The percentage of protein in WPC depends on how concentrated it is. 3  Lower end concentrates tend to have 30% protein and higher end up to 90%.
The Lake Bottom. Conditions at the bottom of large ponds and lakes do not change much throughout the year but dramatic changes in abundance of particular amoebae have been noted (O'Dell, 1979).
Microbes, such as bacteria are sensitive to the hydrogen ion concentration they find in their environment. Large proteins, such as enzymes, are affected by pH. Their shape changes (they denature) and the very often brings about an alteration of the ionic charges on the molecule.
