Question
Chapter 3, Problem 25P
Interpretation Introduction
Interpretation:
In each case, it is to be specified whether the designated substituent is axial or equatorial for the given steroid skeleton.
Concept introduction:
The position of axial and equatorial bonds in cyclohexane chair form is
If the two substituents are on the same side of the ring, then they are cis to each other.
If the two substituents are on the opposite side of the ring, then they are trans to each other.

Given a 1,3-dicarbonyl compound (R1-CO-CH2-CO-R2), indicate the formula of the compound obtaineda) if I add hydroxylamine (NH2OH) to give an isooxazole.b) if I add thiosemicarbazide (NH2-CO-NH-NH2) to give an isothiazole.
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.
Predict the molar absorptivity of transferrin.
Predict the absorbance of a solution that’s 1.000 g/L transferrin in a 1.000-cm-pathlength cuvet.
Estimate the g/L of a transferrin solution with an absorbance of 1.50 at 280 nm.
