Why do not all proteins have the same absorption coefficient (ɛ) at 280 nm? Pick one: a.lt is mainly due to the presence of Asp, Glu, Asn, Gln, Arg and His in the protein b.lt is mainly due to the presence of phenylalanine in the protein c.It is mainly due to the presence of tryptophans and tyrosines in the protein d.The statement is incorrect; all proteins have the same (ɛ) at 280 nm
