Being overweight or obese can take a toll on both your physical and mental health
Functional sepiapterin reductase is a homodimeric enzyme which first converts 6-pyruvoyltetrahydropterin to 1-hydroxy-2-oxopropyltetrahydropterin, which is then reduced to 1-oxo-2-hydroxypropyltetrahydropterin, and then finally to 5,6,7,8-tetrahydrobiopterin, BH 4
2.3 GIO evaluation criteria To evaluate GIO development level, mechanical, histomorphometric and biochemical tests are used including dual-energy X-ray absorptiometry (DXA), micro-computed tomography (CT), histomorphometry and biochemistry analysis in serum [44,45,46,47,48]

The transsulfuration pathway is irreversible from cysteine and is reported to only occur in instances when levels of methionine are biologically dispensable but is also regulated by the availability of CSE and a biological need for cysteine (Homocysteine metabolism is reviewed in depth by Azzini et al, 2020)
