What foods do you think are high in 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.
What is the mass percent of oxygen in phenylalanine?
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%.
Why Should phenylalanine give a yellow Color with concentrated nitric acid?
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.
What charge does phenylalanine have at pH of 7.0?
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.
Is the molecule co polar or nonpolar?
The molecule is nonpolar.
What are the phenylalanine's elements?
The formula for phenylalanine is C6H5CH2CH(NH2)COOH. The elements that are present are carbon, hydrogen, nitrogen, and oxygen. This essential amino acid is classified as nonpolar because of the hydrophobic nature of the benzyl side chain.
What type of interaction would you expect between phenylalanine and leucine in a tertiary structure?
Phenylalanine and leucine are both nonpolar amino acids, so they would likely interact through hydrophobic interactions in the tertiary structure of a protein. These interactions help stabilize the protein's structure by minimizing contact with water molecules.
Which enzyme breaks down phenylalanine?
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).
Does Phenylalanine have the same effect as Apartame does?
Phenylalanine is a component in aspartame.
How much phenylalanine does Dr Pepper 10 have?
It has 718mg of phenylalanine.
Is phenylalanine a compound?
Phenylalanine is a compound. Specifically it is 2-amino-3-phenylpropanoic acid.
What is the molecular formula for Phenylalanine?
The molecular formula for phenylalanine is C9H11NO2.
What are the DNA codons for phenylalanine?
There are two codons that code for the amino acid phenylalanine: UUU and UUC.
What codon codes for amino acids phenylalanine did scientist find?
There are two codons that code for the amino acid phenylalanine: UUU and UUC.
Is phenylalanine alchohol?
yup!
Phenylalanine C9H11NO2 is an amino acid used to make proteins It has a molar mass of 165.19 g mol What is the mass percent of oxygen in phenylalanine?
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%.
Why is phenylalanine observed in the urine of a classical PKU patient?
PKU stands for phenylketonuria, the classic symptom of which (and the diagnostic test for the disease) is phenylalanine in the urine. This is a genetic disorder in which the body is unable to process phenylalalanine, so it is excreted in the urine.
