Insulin is like any other protein. This goes for all proteins: if the aminoacid sequence is the same, the protein will always fold the same way. we do not exactly how this works, how each protein knows exactly how to fold.. not yet. If there are errors in translation or transcription than the protein will not fold correctly.
The body has many ways to identify and get rid of these errors, which are quite common. An example that comes to my mind is the PEST sequence, which, if exposed, has a complementarity with lysosoms, and the protein will be hydrolyzed.
Ionotropic receptors are ligand-gated or transmitter gated ion channels. The binding of a neurotransmitter or other ligand to a particular site on a domain of a protein in the receptor causes a conformational change in the protein subunits. This allows a certain ion to pass through, poteitally potassium, sodium or chloride. There are two types of ionotropic receptors, non-NMDA and NMDA. Both are ligand gated receptors, however the NMDA is also voltage gated.
Cholesterol molecules and protein molecules help stabilize the cell membranes. Cholesterol prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity. Cholesterol is only found in animal cells.
A mutation in the CFTR gene causes the protein CFTR to fold improperly. This mutation results in a defective CFTR protein that cannot function properly, leading to the development of cystic fibrosis.
A newly made protein is released by the mRNA during the process of translation when a stop codon is encountered, signaling the end of the protein coding sequence. This triggers the ribosome to release the completed protein chain into the cell.
Primary structure of the protein is simply its amino acid sequence. It is the sequence in which amino acids are added during protein synthesis.
Well you see darling, food is produced from your inner organs. In your viscus cells, the protein molecules are regenerated and then reproduced throughtout your body. This regeneration causes food to be always flowing within your system.
calcium causes that

There are small filters in the kidney called the glomerulus. When a person has lupus, either the lupus causes inflammation in the glomerulus or immune complexes, huge molecules that develop as a result of autoimmune activitiy, clog the filters. The filters are supposed to return good things to the blood and pass garbage through the urine. When the filters are inflamed of clogged, they fail to collect protein and return it to the blood. As a result, protein "leaks" into the urine.
The concentration gradient is what causes molecules to diffuse.
