What is the difference between alanine and glycine amino acids?
The -r group of alanine is -CH3 - which is a non-polar group, while the -r group of glycine is -H - which is an uncharged polar r group.
What is the difference in structure between Alanine and Glycine?
All amino acids consist of a central carbon atom bound to a caboxyl group, an amine group, a single hydrogen and one other molecule term the r group. It is this r group that varies between different amino acids. In alanine the r group is a methyl group (-CH3) and in glycine the r group is simply another hydrogen molecule.
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 molecule has the R group?
In biochemistry, the term "R group" refers to a variable side chain attached to the backbone of a molecule, particularly in amino acids. Each amino acid has a unique R group that determines its properties and functions. For example, in the amino acid alanine, the R group is a methyl group (–CH3). The specific identity and characteristics of the R group play a crucial role in protein structure and function.
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 amino acid has a methyl group as its R group?
Alanine is the amino acid with a methyl group as its R group.
What is the R-group of Alanine?
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 difference between alanine and glycine amino acids?
The -r group of alanine is -CH3 - which is a non-polar group, while the -r group of glycine is -H - which is an uncharged polar r group.

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.
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.
Is Alanine acidic?
Alanine is not considered an acidic amino acid; rather, it is classified as a neutral amino acid. Its side chain consists of a methyl group, which does not possess acidic properties. In physiological conditions, alanine typically exists in its zwitterionic form, where the amino group is positively charged and the carboxyl group is negatively charged, but neither contributes to acidity. Therefore, alanine's characteristics do not classify it as acidic.
What part of an amino acid is not the same in all amino acids?
The "R" group is different in different kinds of amino acids. The "R" group can be a number of different molecules that are attached to the alpha carbon.
What is the general composition of amino acids?
Generally amino acids have an Amino group (-NH2) and a Carboxyl group (-COOH) attached to the same carbon atom, which is also called as Alpha carbon. Besides Hydrogen and R-Group is also attached with this carbon atom. R may be hydrogen, CH3 or any other group. For Example:If R-group is hydrogen then it is called glycine or if it is CH3 then it is called alanine.
What is the chemical characteristic of alanine?
Alanine is an amino acid. As such it can form peptide bonds with other amino acids to form a primary protein structure.Alanine is non-polar with a small side chain. This means that it is found either in regions of a protein embedded in the cell membrane, regions where protein subunits come together to form complex or regions within a single protein that would not be exposed to the polar cytosol. If you don't get this, read up on hydrophobic interactions if you can; it'll help.Alanine is a chiral molecule so it is either left (S or L) or right (D or R) handed. In proteins it will always be L-alanine.Alanine can also be involved in glucose metabolism. Alanine aminotransferase is used to transfer an amino group from Glutamate to pyruvate, making Alanine and 8-oxo-glutarate (aka a-keto-glutarate) which is important in the TCA cycle.
