Assuming all three carbon atoms of glycerol are labeled as C14 radioisotopes and the radioisotope-labeled glycerol undergoes metabolism in animals. All of the following molecules in the animal may contain C14 radioisotopes EXCEPT: a. Pyruvate
b. Acetyl-CoA
c. Glutamine
d. Fattyacids
e. Oxaloacetate
f. All of the above molecules may contain C14 radioisotopes

Why is carbon ideal for making different compounds?

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.

The equation picture below shows which type of nuclear reaction u 235 + n x e 134 + sr 100 + 2n
