How do you dissolve phenylalanine?

All Answers (5) The solubility of phenylalanine increases dramatically at pH values above 10 or below 2. You could try dissolving the compound in 0.1M NaOH or 0.1M HCl, as long as your cell culture medium is properly buffered, before addition to the bacterial culture.

Why is phenylalanine added to food?

This neurotransmitter enhances mental alertness and memory and improves mood. It also suppresses appetite, which is probably the reason for the mention of Phenylalanine on food labels – an indication that it might be used as a ‘dietary aid’.

QUICK LINKS. Solubility : Soluble in water (30 mg/ml), methanol (slightly), 1 M HCl (50 mg/ml), ethanol (<1 mg/ml at 25° C), and DMSO (<1 mg/ml at 25° C).

Is phenylalanine acidic or basic?

. It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine. This essential amino acid is classified as neutral, and nonpolar because of the inert and hydrophobic nature of the benzyl side chain.

Potatoes are an exception (see Phenylalanine allocation in the diet section). Also, cooked crisps (snacks) made from vegetables such as beetroot or parsnips are concentrated in phenylalanine and should be calculated/measured in the daily phenylalanine allowance.

What is the role of phenylalanine in the body?

Function: The essential amino acid L-phenylalanine (Phe) is needed for the synthesis of proteins, catecholamines, and melanin; it is also an important precursor of the amino acid L-tyrosine (Tyr).

Soy protein supplements can provide about 2.5 grams of phenylalanine per 200-calorie serving ( 5, 29 ).

What is phenylalanine deaminase?

Phenylalanine deaminase medium tests the ability of an organism to produce the enzyme deaminase. Microorganisms capable of producing phenylalanine deaminase remove the amine (NH2) from phenylalanine and releases the amine group as free ammonia.
