However, succinyl-CoA can also be generated through the catabolism of other amino acids, such as isoleucine, or the short-chain fatty acid propionate, produced by gut bacteria
It is a biologically active fraction of vitamin B 12 that can be readily taken up by all cells and represents only 6% to 20% of total serum vitamin B 12 .23 In vitamin B 12 deficiency, serum level of holotranscobalamin decreases even before elevation in homocysteine and MMA levels occurs.24 It has been shown that holotranscobalamin is the most sensitive marker for vitamin B 12 deficiency, followed by MMA.23 25 Like homocysteine and MMA, holotranscobalamin cannot be tested in renal patients as its level increases in renal impairment.23 Furthermore, higher cost and lesser availability than homocysteine and MMA testing make it difficult to acquire wide clinical acceptance
That improves pain, but does not by itself prove a direct GLP-1 tissue effect
