The titration curve of phenylalanine shows the pH changes as a strong acid or base is added to a solution of phenylalanine. At low pH, the carboxyl group is protonated and the amino group is deprotonated. As the pH increases, the carboxyl group loses a proton first, followed by the amino group. The curve typically shows two distinct equivalence points corresponding to the two acidic pKa values of phenylalanine.
Foods high in phenylalanine include red meat, poultry, fish, cheese, seeds, nuts, soy products, and some artificial sweeteners. It is important for people with phenylketonuria (PKU) to monitor their intake of phenylalanine as they have difficulty metabolizing this amino acid.
The molecular formula of phenylalanine is C9H11NO2. To calculate the mass percent of oxygen in phenylalanine, we first need to calculate the molar mass of the compound. This molar mass is found to be 165.19 g/mol. The mass percent of oxygen in phenylalanine is then found to be (32.00 g/mol / 165.19 g/mol) * 100 ≈ 19.38%.
Phenylalanine gives a yellow color with concentrated nitric acid due to the formation of a nitro derivative. Nitric acid reacts with the aromatic ring of phenylalanine, leading to the formation of a yellow compound.
Phenylalanine is an amino acid with a pKa around 2.2. At a pH of 7.0, phenylalanine will have a net neutral charge, as the carboxyl group (pKa ~2.2) will lose its proton and the amino group (pKa ~9.1) will be protonated.

The enzyme phenylalanine hydroxylase breaks down phenylalanine into tyrosine. This enzyme is essential for the conversion of phenylalanine to tyrosine in the body. Deficiency in this enzyme can lead to a build-up of phenylalanine, which can result in a condition called phenylketonuria (PKU).
Phenylalanine is a component in aspartame.
It has 718mg of phenylalanine.
Yes, phenylalanine is an amino acid and is considered as a compound.
The molecular formula for phenylalanine is C9H11NO2.
There are two codons that code for the amino acid phenylalanine: UUU and UUC.
Scientists found that the codon UUC codes for the amino acid phenylalanine.
yup!
The molar mass of oxygen in phenylalanine is 16.00 g/mol. To calculate the mass percent of oxygen in phenylalanine, divide the molar mass of oxygen by the molar mass of phenylalanine, then multiply by 100. (16.00 g/mol / 165.19 g/mol) * 100 = 9.68% Therefore, the mass percent of oxygen in phenylalanine is approximately 9.68%.
Phenylalanine is observed in the urine of a classical PKU (phenylketonuria) patient because they lack an enzyme called phenylalanine hydroxylase, which is needed to convert phenylalanine into tyrosine. As a result, phenylalanine accumulates in the body and is excreted in the urine. This buildup can lead to various health issues if not managed properly.
A genetic disorder in which the essential digestive enzyme phenylalanine hydroxylase is missing is known as Phenylketonuria (PKU). This leads to a buildup of phenylalanine in the body, which can be toxic to the brain if not managed properly through a restricted diet low in phenylalanine.
