Which amino acid is the most hydrophobic? (1pt)

Arginine

Aspartic Acid

Leucine

Serine

Tyrosine

Expert Solution

LEUCINE is most hydrophobic among these amino acids.

Most protein molecules have a hydrophobic core, which is not accessible to solvent and a polar surface in contact with the environment (although membrane proteins follow a different pattern). While hydrophobic amino acid residues build up the core, polar and charged amino acids preferentially cover the surface of the molecule and are in contact with solvent due to their ability to form hydrogen bonds.

Hydrophobic amino acids are mostly buried within the core of the structure, a smaller fraction of polar groups are found to be buried. Charged residues are exposed to solvent to a much higher degree.

6. A bacterium does not want to waste energy synthesizing the amino acid arginine if arginine is present in its diet. Therefore, when arginine is present, it activates a repressor protein to prevent transcription of genes that code for enzyme to make arginine. This is an example of what type of regulation? Please describe the mechanism of this regulation. 7. Prokaryotic genetic information transferring processusually acts as target of antibiotics. We observed a new compound with antibiotic action, and we...

Consider a 0.487 L solution of the amino aspartic acid (0.685 M), which ahs a carboxylic acid group (pKa = 2.10), an amine group (pKa = 9.82), and a carboxylic acid side chain (pKa = 3.86). How many liters of 2.59 M NaOH would you need to add to reach the isoelectric point of the amino acid?

You have accidentally mixed a bunch of amino acids (tryptophan, tyrosine, alanine, selenocysteine, proline, arginine) together and once your boss finds out, you will be fired on the spot. Your only hope of saving your job is to separate them before anyone finds out. You decide that the only viable option is to use ion exchange chromatography. Explain, in detail, how you would do this?

A mutation replaces the original amino acid, leucine, with threonine in a large protein. The altered protein still functions, but less efficiently. What amino acid might replace leucine but with less effect on protein functions? What amino acid might replace leucine but with even a worse effect on the how the protein functions? a) less effect if lysine; worse if alanine b) less effect if methionine; worse if lysine c) less effect if methionine; worse if alanine d) less effect...

The amino acid leucine has two titratable groups, the α-amino, pKa 9.6 and the α-carboxyl, pKa 2.4. Calculate the ratio of acidic and basic forms and express them as [A]/[HA] ratio or [B]/[BH] of the titrating group at the following pH values: α-carboxyl @ 1.4, 1.9, 2.4, 2.9, 3.4; α-amino @ 8.1, 8.6, 9.1, 9.6, 10.1. Plot pH vs. [B]/[BH] for each group, on the same graph. Compare similarities or disparities in the titration of each group.

L-Serine is an amino acid that often is provided when intravenous feeding solutions are used to maintain the health of a patient. Molecular weight of 105, produced by fermentation and recovered and purified by crystallization at 10C. Yield is enhanced by adding methanol to the system, thereby reducing serine solubility in aqueous solutions. An aqueous serine solution containing 30wt% serine and 70wt% water is added along with methanol to a batch crystallizer thatis allowed to equilibrate at 10C. The resulting...
