The average fuel value of fats is 9kcal / g . A 1 oz French fries typically contains 4.5 g of fat. What is the fuel value in kcal) of a medium size French fries from McDonalds ( about 115 g)? Assume that fat is the only fuel source . (1oz = 454g) Use dimensional /unit analysis to solve this problem.

My professor hasn’t gone over how to solve a problem like this and I don’t remembering doing problems like this in math, I need help figuring out how to solve this problem.

The standard curve provided below will allow you to answer the remaining questions. Generic Standard Curve 0.7 y = 0.9425x- 0.0034 0.6 0.5 0.4 0.3 02 0.1 0.1 0.2 0.3 0.4 0.5 0.6 0.7 Concentration (mg/ml) - Please describe two ways in which you could use this standard curve to determine the concentration of a pigment in an unknown sample.| #1: #2: -What is your rough estimation of the concentration if you determine the absorbance of a sample is 0.150? Absorbance

Glucose-1-phosphate has a ΔG°′ value of −20.9 kJ/mol, whereas that for glucose-6-phosphate is −12.5 kJ/mol. After reviewing the molecular structures of these compounds, explain why there is such a difference in these values.

Casein, a protein in milk, has a molecular formula C38H57O9N9. Determine the total BOD, carbonaceous BOD, and nitrogenous BOD of casein in units of “grams BOD per gram of casein”

A purified protein fraction has a total sample volume of 450 µL. The sample has a corrected A280 of 0.244, and the blank corrected A280 was 0.077. (Both values were measured with a path length of 1.00 cm.) If 5.50 µL of the sample was used in a reaction, calculate the mass of protein in the reaction (in µg).

Acetocholinesterase is an enzyme possessing a single active site that metabolizesacetylcholine with a turn over number of 1.4 x 10^4s-1. How many grams of acetylcholine(molecular formula C7NO2H16+) will 2.16 x 10^-6 g acetocholinesterase metabolize in 60minutes? (The enzyme’s molecular mass is 4.2 x 10^4 g/mol).

A purified protein fraction has a total sample volume of 360 µL.  The sample has a corrected A280 of 0.484, and the blank corrected A280 was 0.052.  (Both values were measured with a path length of 1.00 cm.)  If 5.00 µL of the sample was used in a reaction, calculate the mass of protein in the reaction (in µg).

Plasma or serum LDL-Cholesterol (LDL-C) can be calculated by determining concentrations of total plasma (serum cholesterol (T-C), HDL-Cholesterol (HDL-C) and total plasma (serum) triglycerides(TG) using Friedewald equation: LDL-C = (T-C) - (HDL-C) - TG/5. What is the scientific basis for this equation? What are the limitations of this equation?
