Question
Chapter 5, Problem 1EQ
Interpretation Introduction
Interpretation: The supply arrows in the laboratory synthesis of a steroid are to be interpreted.
Concept introduction: The reaction mechanism can be defined as the process of the sequence of the reaction steps that shows the conversion of reactant to intermediate. These intermediates can further convert to the product molecules.
Expert Solution & Answer

Answer to Problem 1EQ
Explanation of Solution
In the given reactant, there is an enolate ion that must react with the carbonyl oxygen atom to form the given intermediate. The shifting of pi electrons over the oxygen atom gives it three lone pairs and causes a negative charge on it. Hence the arrows must be as given below;
Conclusion
The enolate ion can form the cyclic ring in the presence of a carbonyl oxygen atom.

An orange laser has a wavelength of 610 nm. What is the energy of this light?
The molar absorptivity of a protein in water at 280 nm can be estimated within ~5-10% from its content of the amino acids tyrosine and tryptophan and from the number of disulfide linkages (R-S-S-R) between cysteine residues:
Ε280 nm (M-1 cm-1) ≈ 5500 nTrp + 1490 nTyr + 125 nS-S
where nTrp is the number of tryptophans, nTyr is the number of tyrosines, and nS-S is the number of disulfide linkages. The protein human serum transferrin has 678 amino acids including 8 tryptophans, 26 tyrosines, and 19 disulfide linkages. The molecular mass of the most dominant for is 79550.
