An R group is the chemical group attached to the alpha carbon in an amino acid.
In proteins all amino acids have the same basic structure and vary only in their R group. There are 20 standard amino acids found in proteins, which all have different R groups.
For example an amino acids with Hydrogen from its R group is glycine, and one carbon with 3 hydrogens (a methyl group) is the R group for alanine.

What is the three-letter code for the amino acid alanine?
The three-letter code for the amino acid alanine is Ala.
What is the property of alanine that helps it explain its reaction to water?
The amino acid alanine is non-polar, it has a neutral charge, not positive or negative, and it is hydrophobic.
What type of bond is formed between alanine and valine?
A peptide bond is formed between alanine and valine during protein synthesis. This covalent bond forms between the carboxyl group of alanine and the amino group of valine.
What molecule is made when glycine and alanine are added together?
When glycine and alanine are added together, a dipeptide called alanylglycine is formed by a peptide bond between the carboxyl group of alanine and the amino group of glycine.
Is alanine strong acid?
No, alanine is not a strong acid. It is a nonpolar, aliphatic amino acid that is not typically classified as an acid in the context of strong acids and bases.
How is the reduction of plasma alanine concentration caused by gluconeogenesis?
Alanine is the major gluconeogenic amino acid. Plasma alanine is used to make glucose in the liver (Glucose-Alanine Cycle), and thus when this occurs plasma alanine concentration is decreased.
In the glucose alanine cycle how much glucose production does alanine account for?
1.0 gram of alanine accounts for the production of approximately 0.681 grams of glucose in the glucose-alanine cycle.
Can alanine be hydrolyzed?
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.
What are four names of an amino acid?
Alanine Glycine Phenyl alanine Argenine Histidine Tyrosine
The Literature value of enthalpy ionization of alanine?
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.
What makes up the polypeptide alanine?
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.
What is the code for alanine?
ala
What is ALT?
Alanine aminotransferase
What is the three-letter code for the amino acid alanine?
The three-letter code for the amino acid alanine is Ala.
What is the property of alanine that helps it explain its reaction to water?
The amino acid alanine is non-polar, it has a neutral charge, not positive or negative, and it is hydrophobic.
Show how alanine could be deaminated to give the end-products indicated alanine pyruvic acid of what value is deamination to a microbe?
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.
What does the L stands for in L-Alanine?
The "l" should be lower case and in italic, and it can be spelled in full as "levo-". It describes the "handedness" of the amino acid molecule. The prefix "levo-" defines one orientation and "dextro-" the other possible orientation; as "l-Alanine" and "d-Alanine"; or, "dl-Alanine" for the racemic mixture of the two configurations of Alanine.
