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
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.
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.
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.
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.
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.
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.
"Buffers" would be the plural.
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.
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.
Polypeptides are short chains of amino acids, they have no functionality as a protein (long amino acid) would have.
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.
Amino acids
AGT codes for the amino acid serine and CTT codes for the amino acid leucine.
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.
Ch3cooh
It is an nonessential amino acid but I would not call it's structure that simple.
