Interpretation Introduction

Interpretation:

The structure of missing compounds present in Wohl degradation reaction is to be stated. The curved-arrow mechanism for conversion of B to C and C to arabinose in the Wohl degradation reaction is to be shown.

Concept Introduction:

Wohl degradation is the reaction to convert aldose into other aldose with one carbon less. It is a chain contraction reaction of aldoses. The oxime of aldose is formed by reacting it with hydroxylamine and sodium methoxide. Then oxime will react with acetic anhydride in acetic acid and sodium acetate toform nitrile derivative. In the last step, the reaction with sodium methoxide in methanol results in removal of all acetate group and nitrile group toform aldose with one carbon lesser and sodium cyanide as by product.

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.
