This helps achieve maximal cellular betaine concentration to allow this molecule to maintain optimal recycling of homocysteine back to methionine while at the same time provides optimum cellular osmotic maintenance to maximize energy sparing
In the presence of elevated oxidative stress, such as in iron overload, sarcoplasmic reticulum Ca 2+ leaks through the Ca 2+ release channels (62), sarcoendoplasmic reticulum Ca 2+ -ATPase activity is inhibited, the sodium-calcium exchanger currents are elevated (63), and L-type calcium channels are reduced (64, 65)
Homocysteine is converted through two enzymes into the amino acid cysteine
