What part of DNA gives the molecule a negative charge?
The phosphate groups in the DNA molecule give it a negative charge.
Which ion carries the chromophore in an acidic dye?
The sulfonate ion carries the chromophore in an acidic dye. When it attaches to a colored molecule and gives it a negative charge, it results in an acid dye.
Is ethanol positive or negative polarity?
Ethanol is a polar molecule due to the presence of the hydroxyl (-OH) group, which leads to uneven distribution of charge within the molecule. This gives ethanol a positive and negative end, making it a polar solvent.
What is the normal reading for calcium in the body?
The serum level of calcium is closely regulated with a normal total calcium of 2.2-2.6 mmol/L (9-10.5 mg/dL) and a normal ionized calcium of 1.1-1.4 mmol/L (4.5-5.6 mg/dL). The amount of total calcium varies with the level of serum albumin, a protein to which calcium is bound. The biologic effect of calcium is determined by the amount of ionized calcium, rather than the total calcium. Ionized calcium does not vary with the albumin level, and therefore it is useful to measure the ionized calcium level when the serum albumin is not within normal ranges, or when a calcium disorder is suspected despite a normal total calcium level.Corrected calcium levelOne can derive a corrected calcium level when the albumin is abnormal. This is to make up for the change in total calcium due to the change in albumin-bound calcium, and gives an estimate of what the calcium level would be if the albumin were within normal ranges.Corrected calcium (mg/dL) = measured total Ca (mg/dL) + 0.8 (4.0 - serum albumin [g/dL]), where 4.0 represents the average albumin level in g/dL. in other words, each 1 g/dL decrease of albumin will decrease 0.8 mg/dL in measured serum Ca and thus 0.8 must be added to the measured Calcium to get a corrected Calcium value.Or: Corrected calcium (mmol/L) = measured total Ca (mmol/L) + 0.02 (40 - serum albumin [g/L]), where 40 represents the average albumin level in g/Lin other words, each 1 g/L decrease of albumin, will decrease 0.02 mmol/L in measured serum Ca and thus 0.02 must be added to the measured value to take this into account and get a corrected calcium.When there is hypoalbuminemia (a lower than normal albumin), the corrected calcium level is higher than the total calcium.
Can oxygen have a negative charge?
Oxygen can have a negative charge when it gains an extra electron, forming an oxide ion (O2-). This extra electron gives the oxygen atom a negative charge, making it more stable by achieving a full outer electron shell.
Why albumin gives positive Molisch test?
Because it is a carbohydrates and molisch test will be positive in the presence of carbohydrates
Why albumin gives a positive result for protein?
Albumin gives a positive result for protein because it is a major protein found in blood plasma, accounting for a significant portion of total protein levels. In laboratory tests like the Biuret test or urine dipstick, albumin reacts with specific reagents to produce a color change, indicating the presence of protein. This reaction is sensitive to the peptide bonds found in proteins, including albumin, making it a reliable marker for protein detection. Elevated levels of albumin may indicate conditions such as kidney disease or inflammation.
Why does the number of negative factors affect the signs of the product in math equations?
Multiplying or dividing a positive and negative gives a negative result. Multiplying or dividing two negatives gives a positive result.
What number equals 8 squared?
64
Why do disaccharides and polysaccharides give positive Molisch Test?
simply because they are carbohydrates, all carbohydrates produces positive result in molisch's test All carbohydrates i.e. monosacchardes, dissacharides and polysaccharides are dehydrated (lose water) by a dehydrating agent (e.g. Sulphuric acid) they form aldehydes known as furfurral. The furfurral reacts with a component known as 1- naphthol present in Molisch reagent resulting in a reddish violet colour forming between the Reagent and the previous mixture of the carbohydrate and thedehydrating agent. It is important to note that the reaction is more rapid with simple sugars or monosaccharides
What number multiplied by 6 gives you a negative 18 as a result?
6 X -3 = -18 so negative three.
Why the conjugation only change the sign of the imaginary part?
when you square a negative number you also get a positive result (because a negative times a negative gives a positive)
What is the answer to -22 x 22?
A negative number multiplied by a positive number gives a negative result, so -22 times 22 is -484
What is 16 minus negative 12?
28. Subtracting a negative number gives the same result as adding a positive.
Which sample gives a negative Biuret test and why?
Gelatin and egg albumin.
Can a negative number be a square?
the square is positive always.Except in the case of an Imaginary number. An imaginary number is a number that gives a negative result when squared,where i= √-1
What is the implication of albumin in your daily living?
Albumin gives your blood 'weight'. It maintains the oncotic pressure of blood and prevents water leaving the blood abnormally by osmosis and draining into the cells.
