α-淀粉酶能水解淀粉中的α-1,4-葡萄糖苷键。能将淀粉切断成长短不一的短链糊精和少量的低分子糖类,从而使淀粉糊的黏度迅速下降,即起到降低稠度和“液化”的作用,所以此类淀粉酶又称为液化酶。

(1) 2-Oxoglutarate + NADPH + NH4+ → L-glutamic acid + NADP+ + 
H2O
                     (urease)
(2) Urea + H2O → 2 NH3 + CO2

(arginase)
(3) L-Arginine + H2O → urea + ornithine

Kit size:                             50 assays
Method:                              Spectrophotometric at 340 nm
Reaction time:                    ~ 20 min [ammonia (2 min), urea (6 min),
L-arginine (7 min)] Detection limit:                  0.07 mg/L (ammonia)
0.13 mg/L (urea)
0.37 mg/L (L-arginine)
Application examples:
Grape juice, wine must, wine and other materials (e.g. biological
cultures, samples, etc.)
Method recognition:          Improved method

Advantages

  • Improved assay format
  • Very rapid reactions due to use of uninhibited glutamate dehydrogenase
  • All enzymes supplied as stabilised suspensions
  • Very competitive price (cost per test)
  • All reagents stable for > 2 years after preparation
  • Mega-Calc™ software tool is available from our website for hassle-free raw data processing
  • Standard included
  • Extended cofactors stability

商品说明:

The Glycerol GK test kit is a simple, reliable and accurate method for the measurement and analysis of glycerol in beverages, foodstuffs and other material. Based on use of ADP-glucokinase and increase in absorbance on conversion of NAD+ to NADH.
Extended cofactors stability. Dissolved cofactors stable for > 1 year at 4oC.
Suitable for manual, auto-analyser and microplate formats.

UV-method for the determination of Glycerol in foodstuffs,
beverages and other materials

Principle:
(glycerokinase)
(1) Glycerol + ATP → L-glycerol-3-phosphate + ADP

(ADP-GK)
(2) ADP + D-glucose → G-6-P + AMP

(glucose-6-phosphate dehydrogenase)
(3) G-6-P + NAD+ → gluconate-6-phosphate + NADH + H+

Kit size: 70 assays (manual) / 700 (microplate)
/ 600 (auto-analyser)
Method: Spectrophotometric at 340 nm
Reaction time: ~ 7 min
Detection limit: 0.37 mg/L
Application examples:
Wine (and grape juice), beer, spirits, vinegar, marzipan, fruit juices,
soft drinks, toothpaste, honey, tobacco, paper (and cardboard),
cosmetics, pharmaceuticals, soap and other materials (e.g. biological
cultures, samples, etc.)
