Histidine is the amino acid that function at the physiological PH.

The reason being that the Pka value of his is 6.8 close to the

physiological PH of the blood i.e. 7.4

How you prepare 10 mM phosphate buffer from 0.5 M phosphate buffer?

To prepare a 10 mM phosphate buffer from a 0.5 M phosphate buffer, you would need to dilute the 0.5 M buffer by a factor of 50. Calculate the volume of the 0.5 M buffer needed and add water to make up the total volume needed. For example, to make 100 mL of 0.5 M phosphate buffer into 10 mM, you would take 2 mL of the 0.5 M buffer and dilute it to 100 mL with water.


What is the pH of Triethylammonium acetate buffer?

The pH of a buffer solution containing triethylammonium acetate would depend on the concentration of the components. Typically, a buffer solution made from triethylammonium acetate and acetic acid would have a slightly acidic pH, around 4 to 5.5.


How many bases are needed to make 3 amino acids?

To make 3 amino acids, you would need at least 9 bases. This is because each amino acid is encoded by a sequence of 3 bases called a codon. So, 3 amino acids would require 3 codons, which would be 9 bases in total.


Why are acidic amino acids negatively charged and vice versa i thought adding H plus ions to make it acidic would make it positive?

Acidic amino acids like aspartic acid and glutamic acid are negatively charged at physiological pH because they can release a proton (H+) to become deprotonated. This deprotonation results in the formation of a negatively charged carboxylate group. Adding protons (H+) to an amino acid can make it positively charged, but in the case of acidic amino acids, the carboxyl group is the one that typically donates a proton.


What would the effect of reagent such as control buffer substrate buffer and ascorbic acid be on the browning process?

A control buffer would maintain the experimental conditions without affecting the browning process. Substrate buffer might provide necessary components for the enzymatic reaction to occur, while ascorbic acid could inhibit browning by reducing enzymatic activity and preventing oxidation of phenolic compounds.

That would depend on the size of the buffer.


Over what pH range would Glycine be a useful buffer?

Glycine is a useful buffer anywhere from 8.6 to 10.6 range. By utilizing Glycine stock agents in the buffer, it's entirely possible to create 21 different PH levels.


What is the plural for buffer?

"Buffers" would be the plural.


Which animal's amino acid sequence was most similar to that of the horse?

The amino acid sequence most similar to that of a horse would likely be that of a close relative in the Equidae family, such as a donkey or a zebra. Due to shared ancestry, these animals would have a high degree of sequence similarity with horses.

Why are amino acids referred to as a polypeptide?

Polypeptides are short chains of amino acids, they have no functionality as a protein (long amino acid) would have.

What amino acid would be made form the mRNA code for a a a?

AGT codes for the amino acid serine and CTT codes for the amino acid leucine.


What would Hydrolysis of a protein produce?

Hydrolysis of a protein would break down the protein into its constituent amino acids. This process involves adding water to the protein molecule, causing the peptide bonds between amino acids to be cleaved, resulting in the release of individual amino acids.
