COO A, at pH < 1.82 B. between pH 1.82 and pH 6.0 C) between pH 6.0 and pH 9.17 D. at...
Tyrosine is a normally nonessential amino acid, but some people with a genetic defect in phenylalanine hydrolase require tyrosine in their diet for a normal growth. Explain a reason for this.
Which of the following amino acid residues are often involved in proton transfers in enzyme-catalyzed reactions? Select one: Histidine, aspartate, lysine, and serine Histidine, aspartate, glutamate, arginine, and lysine. Glutamine, asparagine, lysine, and tyrosine Histidine, aspartate, serine, and cysteine Serine, tyrosine, arginine, and cysteine
Justify with structure why arginine (pI=) is a more basic amino acid than histidine (pI=) is.

(L)-Tyrosine is a nonessential amino acid that is synthesized in the body from phenylalanine. As a building block for several important brain chemicals, tyrosine is required to make epinephrine, norepinephrine, serotonin, and dopamine, all of which work to regulate mood. Therefore, deficiencies in tyrosine have been associated with depression. In addition, tyrosine aids in the production of melanin (pigment responsible for hair and skin color) and in the function of organs in the body responsible for making and regulating hormones,...
