(a)
Interpretation:
Structure of lecithin and the naturally occurring enantiomer need to be drawn and if phosphodiester is in C2 position will there be chirality has to be discussed.
Concept introduction:
Phosphoglycerides are same as triglycerides but the only difference is that in triglycerides there are three fatty acid residues. But in phosphoglyceride one of the fatty acid residue in triglyceride is replaced by a phosphoester. Hydrolysis of phosphoglycerides yield glycerol, fatty acid, phosphate.
To draw: the structure of lecithin
(b)
Interpretation:
Structure of lecithin and the naturally occurring enantiomer need to be drawn and if phosphodiester is in C2 position will there be chirality has to be discussed.
Concept Introduction:
Chirality is the ability of the compound to rotate the plane polarized light when it is passed through them. A chiral center is the one when the carbon atom is attached to a four different groups. If the plane polarized light is rotated clockwise then the compound is said to be dextrorotatory and if it is anti-clockwise then the compound is levorotatory.
(c)
Interpretation:
Structure of lecithin and the naturally occurring enantiomer need to be drawn and if phosphodiester is in C2 position will there be chirality has to be discussed.

If the plane polarized light is rotated clockwise then the compound is said to be dextrorotatory and if it is anti-clockwise then the compound is levorotatory. If the carbon is not attached to four different groups means then it is said to be achiral.

- Nonearrow_forwardCarbohydrates- Draw out the Hawthorne structure for a sugar from the list given in class. Make sure to write out all atoms except for carbons within the ring. Make sure that groups off the carbons in the ring are in the correct orientation above or below the plane. Make sure that bonds are in the correct orientation. Include the full name of the sugar. You can draw out your curve within the text box or upload a drawing below.arrow_forwardHow many milliliters of 97.5(±0.5) wt% H2SO4 with a density of 1.84(±0.01) g/mL will you need to prepare 2.000 L of 0.110 M H2SO4? If the uncertainty in delivering H2SO4 is ±0.01 mL, calculate the absolute uncertainty in the molarity (0.110 M). Assume there is negligible uncertainty in the formula mass of H2SO4 and in the final volume (2.000 L) and assume random error.arrow_forward

Assume there is negligible uncertainty in the formula mass of NaOH and in the final volume (2.000 L) and assume random error.arrow_forwardYou are tasked with creating a calibration curve for the absorbance of cobalt solutions of various concentrations. You must prepare 5 standards with concentrations between 1.00 mg/L and 10.0 mg/L Co2+. You have a stock solution with a concentration of 40 mg/L Co2+ and all the standard lab glassware including transfer pipets and flasks. Explain how you would make your 5 standard solutions of various concentrations, including what glassware you would use to measure and prepare each solution.arrow_forward

Specifically, where does it come in during rubber or textile production and what is the chemical processes?arrow_forwardA researcher has developed a new analytical method to determine the percent by mass iron in solids. To test the new method, the researcher purchases a standard reference material sample that is 2.85% iron by mass. Analysis of the iron standard with the new method returns values of 2.75%, 2.89%, 2.77%, 2.81%, and 2.87%. Does the new method produce a result that is significantly different from the standard value at the 95% confidence level?arrow_forward
