The systematic name of this enzyme class is pyruvate: d-glyceraldehyde-3-phosphate acetaldehydetransferase (decarboxylating). Other names in common use include 1-deoxy-d-xylulose-5-phosphate pyruvate-lyase (carboxylating), and DXP-synthase. This enzyme participates in biosynthesis of steroids.
The enzyme involved in making 1-deoxy-d-xylulose 5-phosphate (DXP) is DXP synthase. [2] The mechanism follows a catalysis of decarboxylative condensation of pyruvate and d-glyceraldehyde 3-phosphate to produce DXP. [2] [3] In addition, the molecule is involved in making thiamine (vitamin B 1) and pyridoxol (vitamin B 6). [2]
This pathway, called methyl-D-erythritol phosphate (MEP) or non-mevalonate pathway, is responsible for biosynthesis of isoprenoids—molecules required for cell survival in most pathogenic bacteria and hence will be helpful in most usually antibacterial resistant bacteria. [17]
Trace levels of protein in the urine can be normal, [60] but high levels (proteinuria) can indicate kidney disease. [45] Most cases of proteinuria are caused by increased levels of albumin , [ 61 ] which test strips can detect relatively well; but they are markedly less sensitive to other proteins, such as Bence-Jones protein , [ 62 ] which may ...
Even when low phosphate is measured, its significance is often overlooked. The next most appropriate test is measurement of urine phosphate levels. If there is inappropriately high urine phosphate (phosphaturia) in the setting of low serum phosphate (hypophosphatemia), there should be a high suspicion for tumor-induced osteomalacia.

D-Xylulose 5-phosphate (D-xylulose-5-P) is an intermediate in the pentose phosphate pathway. It is a ketose sugar formed from ribulose-5-phosphate by ribulose-5-phosphate epimerase. In the non-oxidative branch of the pentose phosphate pathway, xylulose-5-phosphate acts as a donor of two-carbon ketone groups in transketolase reactions. [1]
2.5: 6.25: mmol / 24 h: An abnormally high level is called hypercalciuria and an abnormally low rate is called hypocalciuria. 14637-3: 100 [8] 250 [8] mg / 24 hours: 6874-2: Phosphate (P) – per day: n/a [5] 38 [5] mmol / 24 h: Phosphaturia is the hyperexcretion of phosphate in the urine. This condition is divided into primary and secondary types.
