During gluconeogenesis, alanine is converted into pyruvate and then used in the process to produce glucose. This results in a decrease in plasma alanine concentration as the alanine molecules are utilized for energy production.
1.0 gram of alanine accounts for the production of approximately 0.681 grams of glucose in the glucose-alanine cycle.
Yes, alanine can be hydrolyzed. Alanine is an amino acid with a carboxylic acid group that can undergo hydrolysis, breaking the peptide bond and producing alanine and other components. This process is commonly carried out by enzymes known as proteases.

The literature value for the enthalpy of ionization of alanine is approximately 170 kilojoules per mole. This value represents the energy required to remove an electron from a gaseous alanine molecule to form a positively charged ion. It is an important parameter in understanding the chemical properties and reactivity of alanine.

Alanine aminotransferase
The polypeptide alanine is composed of a chain of amino acids where each alanine molecule consists of a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain made of a methyl group. The repetitive sequence of alanine molecules linked together forms the polypeptide chain.
The three-letter code for the amino acid alanine is Ala.
The property of alanine that helps explain its reaction to water is its hydrophobic nature. Alanine contains a nonpolar side chain that repels water molecules, making it less soluble in water.
Alanine can be deaminated by the enzyme alanine deaminase to form pyruvic acid. This reaction involves the removal of the amino group (-NH2) from alanine. Deamination is valuable to a microbe as it provides a source of carbon for energy production through the production of pyruvic acid, which can enter the citric acid cycle or be used in gluconeogenesis.
The "L" in L-Alanine designates the configuration of the molecule, indicating that it is in the L-configuration. This designation is based on the spatial arrangement of the molecule's atoms around a central carbon atom.
