Question

The maximum wavelength at which Tryptophan and tyrosine absorbs light?





260nm





257nm





280nm





295nm​

Answer 1

$\huge \red{answer}$

280 nm

Since proteins absorb light at a specific wavelength, measurement can be obtained using a spectrophotometer. Specifically, the amino acids tyrosine and tryptophan have a very specific absorption at 280 nm, allowing direct A280 measurement of protein concentration.

Answer 2

Answer:

280 nm

Since proteins absorb light at a specific wavelength, measurement can be obtained using a spectrophotometer. Specifically, the amino acids tyrosine and tryptophan have a very specific absorption at 280 nm, allowing direct A280 measurement of protein concentration.
