Changes in these electrolytes can not only cause painful hand cramping due to muscle spasm but can also be life-threatening in certain situations. Electrolyte imbalances can be caused by several conditions including but not limited to: kidney disease; severe dehydration; prolonged vomiting from bulimia, pregnancy, or other causes; excessive heat
Protein structure is the biomolecular structure of a protein molecule. Proteins are polymers â specifically polypeptides â formed from sequences of monomer amino acids.
This receptor has a bound peptide (in the binding pocket) of heterologous origin that also contributes to function. In structural biology, a protein subunit is a single protein molecule that assembles (or coassembles) with other protein molecules to form a protein complex. Some naturally occurring proteins have a relatively small number of subunits and therefore described as oligomeric, for example hemoglobin or DNA polymerase.
