Why does 4-aminophenol acetate preferentially on the amino group and not the phenol group?

The reason is nitrogen nucleophiles are more reactive than than oxygen nucleophilies, as nitrogens lone pair of electrons is not held as tightly as the oxygens hence the lone pair on nitrogen is more readilly available.

What amino acid will yield a positive result with lead acetate test?
Cystein and methionie
In lead acetate test what element in the amino acid is detected to be present in this test?
Sulfur is the element. The lead-acetate test detects presence of sulfate or sulfide.
How do nucleotides translate into amino acids?
A codon of nucleotides codes for an amino acid. The combination of nucleotides in a codon determines the amino acid the codon makes.
What are the diseases due to deficiency of sulfur in animals?
No diseases occur. Sulfur helps make amino acids and amino acids make up protein. So deficiency would be a lack in synthesis of amino acids.
What is nitrogen a key element for the formation of?
Amino Acids
What is an aminophenol?

Mode of action of pepsin?
Pepsin, a bovine gastric mucosa enzyme, cleaves peptide bonds of polypeptides specifically to the amino side when the amino acid is a Leucine, Phenylalanine, Tryptophan, or Tyrosine, but not if the terminal carboxyl of the previous amino acid, of the peptide bond to be cleaved, is a Proline.
Names of plastics?

ABS, acrylic, amino plastics, Bakelite, cellophane, cellulose, cellulose acetate, cellulose acetate butyrate, copolymer, elastomer, epoxy resin, ester, GRP, HIPS, LLDPE, melamine, monome, nylon, phenolic, polycarbonate, polyesters, polymer, polymerization, polypropylene, and polystyrene are a majority of the common ones.
What is a positive attribute of dietary fat?
Compared to carbohydrates and protein, fat provides more energy. But it is not always preferentially used by the body. Your body also needs fat to survive because of the amino acids and proteins that come with it
