Question
Chapter 18, Problem 18.54E
Interpretation Introduction
Interpretation:
The role played by estrogens and progesterone in preparation for pregnancy is to be stated.
Concept introduction:
Steroid hormones are the derivatives of cholesterol. It has a messenger function. There are two types of steroid hormones: sex hormones and adrenocorticoid hormones. There are three major subclasses of sex hormones.
• Estrogens-the female sex hormones.
• Androgens-the male sex hormones.
• Progestins-the pregnancy hormones.

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.
