The two primary MTHFR variants are C677T (rs1801133) which substitutes valine for alanine at position 222, reducing enzyme activity by approximately 35% in heterozygotes and 70% in T/T homozygotes at physiological folate concentrations and A1298C (rs1801131) which substitutes glutamate for alanine at position 429, reducing activity by approximately 20% in heterozygotes, with compound heterozygosity (C677T + A1298C) producing effects between the two individual homozygous states
What are the signs and symptoms of Vitamin B12 deficiency
From ubiquinol, the electrons pass down the redox gradient through complex III (coenzyme Q-cytochrome c oxidoreductase) to cytochrome c , then to complex IV (cytochrome c oxidase) and to the final acceptor, oxygen (O 2 ) to produce water
Without adequate reduced glutathione, a cell simply cannot repair its DNA or safely divide
