A student observes 5,000 RFUs in a 200μl aliquot from a G3-500 ml culture. How many total RFUs will be present in a G3-15ml samp

natka813 [3]

Answer:

The maximum no. of RFUs collected in the purification procedure $= 3.05 \times 10^5$ RFUs

Explanation:

No. of RFUs in a 200 ul (0.2ml) aliquot = 5000 RFUs

So, No. of RFUs in G3-500 ml culture $= 5000 \times \frac{500 ml}{0.2 ml}$ RFUs

$= 5000 \times 2500$ RFUs

$= 1.25 \times 10^7$ RFUs

Similarly, No. of RFUs in a G3-15ml sample $= 5000 \times \frac{15 ml}{0.2 ml}$ RFUs

$= 5000 \times 75$ RFUs

$= 3.75 \times 10^5$ RFUs

The maximum no. of RFUs collected in the purification procedure

$= 3.75 \times 10^5 \times 80$ % RFUs

$= 3.75 \times 10^5 \times 0.80$ RFUs

$= 3.05 \times 10^5$ RFUs

What is the function of lipoprotein lipase?

scZoUnD [109]

Answer:

Hydrolysis of triglycerides in lipoproteins

Explanation:

Lipoprotein lipase is a water-soluble enzyme which includes pancreatic lipase, hepatic lipase, and endothelial lipase.

Enzymes involved in triacylglycerol digestion are lipases and they catalyze the partial hydrolysis of triglycerides into a mixture of free fatty acids and acylglycerols. After digestion of lipids, monoglycerides and fatty acids associate with bile salts and phopholipids to form micelles. Micelles are structures that are necessary for the transport the poorly soluble monoglycerides and fatty acids to the surface of the enterocyte. But, micelles cannot be absorbed by epithelial cell, only freely dissolved monoglycerides and fatty acids can.
