basically ,aspartate is more polar than glutamate looking at the fact that ,aspartate has a short side group making it easy to be polarised than glutamate which has an extra methylene and COO-
What else can I help you with?
Why are aspartate and glutamate considered acidic?
Aspartate and glutamate are considered acidic because they contain carboxylic acid functional groups, which can release a hydrogen ion in solution, contributing to the overall acidity of the molecule. This ability to donate protons makes them acidic amino acids.
How many functional groups does the peptide MDFGRKCDE have that can be titrated?
The peptide MDFGRKCDE has four titratable functional groups which are the amino groups on the N-terminus, the side chain amino group of lysine (K), the carboxyl group of aspartate (D), and the carboxyl group of glutamate (E).
What is the three-letter code for the amino acid aspartate?
The three-letter code for the amino acid aspartate is Asp.
What is the three-letter code for the amino acid glutamate?
The three-letter code for the amino acid glutamate is Glu.
What color tube is used for Aspartate aminotransferase test?
A red-top tube is typically used for an Aspartate aminotransferase (AST) test, as it allows for serum collection and subsequent analysis.
Origin of Aspartate transaminase name and what is its normal function?
AST, Systematic name: L-aspartate:2-oxoglutarate aminotransferase. EC.number 2.6.1.1It facilitates the conversion of aspartate and alpha-ketoglutarate to oxaloacetate and glutamate, and vice-versa.Oxaloacetate + glutamate ⇌ aspartate + α-ketoglutarate.It's found in liver, muscles, red blood cells.
Why are aspartate and glutamate considered acidic?
Aspartate and glutamate are considered acidic because they contain carboxylic acid functional groups, which can release a hydrogen ion in solution, contributing to the overall acidity of the molecule. This ability to donate protons makes them acidic amino acids.
Is mono-sodium glutamate polar or non-polar?
Monosodium glutamate (MSG) is a polar molecule. This is because it contains both polar and charged groups within its structure, specifically the carboxylate group of the glutamate moiety and the sodium cation. These polar groups result in an overall polar nature for MSG, making it soluble in polar solvents like water.
What is an amino acid that posses an additional carboxyl group in side chain?
The two amino acids aspartate and glutamate each contain two carboxyl groups.
Is ketamine an agonist or antagonist?
Ketamine is an antagonist at the N-methyl-D-aspartate (NMDA) receptor in the brain. It blocks the action of glutamate, an excitatory neurotransmitter, leading to its dissociative and anesthetic effects.
What are the excitatory neurotranmitters?
Glutamic acid (glutamate) is probably the most abundant excitatory transmitter. Others can be excitatory, such as acetylcholine, and some peptides. Aspartate is also excitatory. Finally, serotonin is often found to be exctitatory.
What is the relationship between asparagine and glutamine?
Asparagine and glutamine share some characteristics, i.e., they are nonessential polar and uncharged amino acids. The most important feature that they share is in the asparagine synthesis. Asparagine comes from the aspartate as substrate of the asparagine synthetase enzyme that incorporates an glutamine molecule to provide an amino group to the substrate, leaving glutamate from the reaction, and in presence of ATP as energetic group.
What is an aspartate?
An aspartate is a salt or ester of aspartic acid.
What are the major intracellular anions?
There are more than 2. Any molecule with a negative charge is an anion. Inside cells, these include bicarbonate, chloride, ATP, and any other molecule with phosphate groups, and amino acids having negative charge (glutamate, aspartate). So, there are a wide variety of intracellular anions.
What is the difference between aspartate and aspartame?
Aspartate is an amino acid that is naturally found in the body and in some foods, while aspartame is an artificial sweetener made from aspartate.
What are the five amino acid families in amino acid biosynthesis?
The five amino acid families in amino acid biosynthesis are the serine family, the aspartate family, the pyruvate family, the alpha-ketoglutarate family, and the aromatic family. These families form the core building blocks for synthesizing all the essential amino acids required by living organisms.
How many functional groups does the peptide MDFGRKCDE have that can be titrated?
The peptide MDFGRKCDE has four titratable functional groups which are the amino groups on the N-terminus, the side chain amino group of lysine (K), the carboxyl group of aspartate (D), and the carboxyl group of glutamate (E).
