Who told you so?
Arginine has four (4!) basic groups (2x -NH2 and 2x =NH) and only one acidic (-COOH).
So only at pH=11.2 there is no net proton gain or loss when it is neutral. Above 11.2 it is negatively charged by loss of H+, below that it is positively charged by gain of one (or two) protons from water.
All this is regarded as 'proton transfer' or (auto)protolyse (zwittering)

What do Proton-Transfer reactions favor?
Proton-transfer reactions typically favor the formation of products that are more stable and have lower energy. This often involves the transfer of a proton to a site that is more basic or can better stabilize the resulting charge.
What does intramolecular proton transfer mean?
Intramolecular proton transfer refers to the movement of a proton within a molecule, typically from one atom to another. This phenomenon often occurs in chemical reactions involving acids and bases, where a proton is transferred from a donor atom to an acceptor atom within the same molecule. Intramolecular proton transfer can affect the molecule's structure, stability, and reactivity.
Which molecules is most directly involved in the transfer of energy from food to the proton pumps?
Adenosine triphosphate (ATP) is the molecule that is most directly involved in the transfer of energy from food to the proton pumps. ATP acts as the primary energy carrier in cells and is used to power various cellular processes, including the pumping of protons across membranes by proton pumps. This proton pumping generates a proton gradient, which is then utilized for the production of ATP.
Which amino acid is coded for by AGA?
The codon AGA codes for the amino acid arginine.
At the pH of most bodily fluids which functional group will lose a proton and which functional group will accept a proton?
At the pH of most bodily fluids (around 7.4), carboxylic acid functional groups (-COOH) typically lose a proton, becoming negatively charged carboxylate ions (-COO⁻). Conversely, amino functional groups (-NH₂) tend to accept a proton, becoming positively charged ammonium ions (-NH₃⁺). This proton transfer is crucial for maintaining the acid-base balance in biological systems.
Does arginine is an acid or base?
Arginine is a basic amino acid, meaning it tends to donate a proton and accept an electron pair in chemical reactions.
Between lysine and arginine which is more basic?
arginine is more basic due to the presence of 3 NH2 groups

Intramolecular proton transfer can affect the molecule's structure, stability, and reactivity.
What determines the extent to which a proton transfer reaction occurs?
The weaker acid and base determine the extent to which a proton-transfer reaction occurs. Acid base reactions are called proton transfers.
Why are acid base reactions called proton transfer?
They are called 'proton transfers' because a proton is transferred from the acid to the base in each acid-base reaction, according to the Bronsted-Lowry definition of acids and bases. The proton is usually in the form of a hydrogen ion, but it doesn't have to be.
What is arginine?
Arginine is an amino acid.
What is the difference between l-arginine and arginine?
Nothing. It is the same.
Are there Protein shakes without l-arginine?
cytogainer does not have arginine!
Who discovered arginine?
Arginine was discovered by Ernst Schultze in 1886. Ernst discovered Arginine when he isolated it from the extract of a Lupin Seedling.
What is the pH of arginine?
The pH of arginine is around 10.76 at 25°C. This means that arginine is considered a basic (or alkaline) amino acid.
What determines the extent to which a proton-transfer reaction occurs?
The extent of a proton-transfer reaction is determined by the relative stability of the products and reactants. If the products are more stable than the reactants, the reaction is more likely to occur to a greater extent. Additionally, factors such as temperature, solvent, and concentration of reactants can also influence the extent of the reaction.
