Supplements and Inflammation. Research has shown that people with RA have low levels of selenium, a mineral found in whole-grain wheat products and shellfish such as oysters and crab. It contains antioxidants, which are believed to help control inflammation.
Conversion of proinsulin to insulin occurs coordinately with acidification of maturing secretory vesicles. Orci L, Ravazzola M, Amherdt M, Madsen O, Perrelet A, Vassalli JD, Anderson RG. Proinsulin is a single polypeptide chain composed of the B and A subunits of insulin joined by the C-peptide region. Proinsulin is converted to insulin during the maturation of secretory vesicles by the action of two proteases and conversion is inhibited by ionophores that disrupted intracellular H+ gradients.
1 Monitor the amount of insulin produced by the beta cells in the pancreas (endogenous); in this case, a C-peptide test may also be done. 2  Insulin and C-peptide are produced by the body at the same rate as part of the conversion of proinsulin to insulin in the pancreas.
