thiocyanate

[¦thī·ō′sī·ə‚nāt]
(inorganic chemistry)
A salt of thiocyanic acid that contains the ‒SCN radical; for example, sodium thiocyanate, NaSCN. Also known as sulfocyanate; sulfocyanide; thiocyanide.

Thiocyanate

 

(also rhodanide), any of the salts of thio-cyanic acid, HSCN. Although most thiocyanates are freely soluble in water, AgSCN, CuSCN, and Hg(SCN)2 are insoluble. Colorless KSCN and NH4SCN are widely used in analytical chemistry for cation detection; for example, with Fe3+ they form bloodred Fe(SCN)3, and with Cu2+ in an ammonium medium they form blue [Cu(NH3)4](SCN)2.

The results show increased archaeal urease activity generating ammonia and thiocyanate in the disease states.
First, it is necessary for patients using amygdalin to have a sufficient source of sulfur in the diet so that any excessive cyanide formed near normal cells can be converted to thiocyanate by the addition of sulfur.
Among those, the most promising alternatives are currently thiourea, thiocyanate, thiosulphate, halides and ammonia [4]:
In conclusion, cassava chip meal in lactating sow diets improves sow milk quality by the increasing thiocyanate and lactoperoxidase content and by reducing total microbes and coliform bacteria content while maintaining sow milk composition on day 14 of lactation.
The investigators found that the antimicrobial activity of the LPS system on target bacteria changed according to the concentrations of hydrogen peroxide and potassium thiocyanate. The growth of all tested bacteria was prevented for a six-hour period using LPS in the presence of 0.4 mM or 0.8 mM of hydrogen peroxide and 4 mM of potassium thiocyanate.
They further commented that thiocyanate, an important component of smoking, was found to be associated with lower levels of T4 and higher levels of T3 and TSH in smokers compared to controls (Banerjee et al., 1997).
The lactoperoxidase enzyme catalyzes the oxidation of thiocyanate by [H.sub.2][O.sub.2] to intermediate hypothiocyanate ([OSCN.sup.-]), which has anti-microbial effect [5].
The total antioxidant activity can be measured using the method FTC (Ferric Thiocyanate) where it was held at the 25 [micro]g/mL concentrations, 50 [micro]g/mL, 75 [micro]g/mL and 100 [micro]g/mL.
