A protein has a molecular mass of 400 kda when measured by gel filtration. When subjected to gel electrophoresis in the presence of sodium dodecyl sulfate (sds), the protein gives three bands with molecular masses of 180, 160, and 60 kda. When electrophoresis is carried out in the presence of sds and dithiothreitol (dtt), three bands are again formed, this time with molecular masses of 160, 90, and 60 kda. Required:
Determine the subunit composition of the protein.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

can you list the answers so i can answer
