Proteins do have charges based on its amino acid content. there are polar uncharged and acidic, basic amino acids exist in the cells(Lysine, Arginine, asparic acid are a few charged groups). Based on the codes of mRNA proteins are formed by these amino acids in a sequence.
The charge on protein depends on what kind of amino acids it have that is it depend on the charge on different amino acids which are the building blocks of proteins.
complete protein
Structural Protein
The ribosomes.
About 11 % protein
DC Charge
Marker Protein.
protein will have a net positive charge due to the protonation of all basic side chains (NH3+) in its structure therefore it will be soluble. If there is a charge at the protein surface, the protein prefers to interact with water, rather than with other protein molecules so makes it more soluble.
negative
most people use whey protein for weightlifting, however you can use it for any kind of exersize if you need the extra protein
a president is in charge
Electrons have a negative charge.
Electrons have a negative charge.
