Enzyme2
- The pyridoxal-5 - phosphate-independent enzyme, 3-mercaptopyruvate sulfurtransferase (3-MST), displays enzymatic activity at a pH of 7.4, generating H 2 S from 3-mercaptopyruvate, which is produced by cysteine aminotransferase (CAT) in mitochondria [ 12 - 14 ] (Figure 1 ). (hindawi.com)
- In this pathway, cysteine is first oxidized to its sulfinic acid, catalyzed by the enzyme cysteine dioxygenase . (cloudfront.net)
Amino acid2
- Beetroot contains betaine and inorganic nitrates Betaine being a naturally-occurring substance and amino acid, found in beetroot which is created by choline, in combination with the amino acid glycine. (nutritiontogo.org)
- Asparagus is high in B vitamins that further sustain stable homocysteine levels that are formed in the blood whenever an amino acid decomposes in the body. (fruitofspirit.com)
Contributes2
- Nonenzymatic processes are primarily produced by the decomposition of an inorganic substance, which contributes a little to the amount of H 2 S production. (hindawi.com)
- Biotin is a water-soluble B-vitamin, also called vitamin B7 and formerly known as vitamin H or coenzyme R. It contributes to normal energy-yielding metabolism, normal functioning of the nervous system, normal macronutrient metabolism, normal psychological function, normal hair and skin and the maintenance of normal mucous membranes. (nutritiontogo.org)
Taurine1
- Taurine is naturally derived from cysteine . (cloudfront.net)
Vitamin1
- A vitamin B deficit in the body can boost homocysteine rates and raise the likelihood of harm to the veins and arteries, venous thrombosis in which blood coagulation occurs in the veins, atherosclerosis, and other heart abnormalities. (fruitofspirit.com)
