Improved biological activity of Gly^ 2-and Ser^ 2-substituted analogues of glucose-dependent insulinotrophic polypeptide
Neurological symptoms often develop gradually and may include: Paraesthesia : tingling or 'pins and needles' sensations, typically starting in the feet and hands Numbness : reduced sensation in the extremities, which may affect balance and coordination Burning pain : particularly in the feet, often worse at night Weakness : muscle weakness and difficulty walking Balance problems : unsteady gait and increased fall risk due to proprioceptive impairment Cognitive changes : memory problems, confusion, difficulty concentrating, and mood disturbances Haematological signs may accompany neurological symptoms and include fatigue, weakness, pallor, and shortness of breath due to megaloblastic anaemia
This is problematic since the functions of these two coenzymes and their metabolic fates are quite different: Consequently, supplementation with methylcobalamin exclusively does not really address the functions of adenosylcobalaminwhich are at least as important as those of methylcobalamin
Summary Selenium exerts various biological functions mainly as part of the amino acid, selenocysteine, which is found in at least 25 selenocysteine-containing proteins (selenoproteins) in humans
