Amino Acid Structures
Amino acids are the building blocks of proteins, and understanding their structures is essential for learning biochemistry. Each amino acid has a common basic structure, consisting of a central carbon atom attached to a hydrogen atom, an amino group (NH2), a carboxyl group (COOH), and a unique side chain known as the R group. The R group varies in size, shape, and chemical properties, giving each amino acid its distinct characteristics.
To help remember the structure of amino acids, the CORN mnemonic can be used. The acronym CORN stands for C (carboxyl), O (R group), and N (amino). This simple mnemonic can serve as a useful tool for quickly recalling the components of an amino acid structure.
“The CORN mnemonic is a handy way to remember the essential components of an amino acid structure: carboxyl group, R group, and amino group.”
It’s important to note that amino acids can exist in two different forms based on their stereochemistry: L-amino acids and D-amino acids. L-amino acids have the amino group situated on the left side of the stereocenter, while D-amino acids have the amino group on the right side. This distinction in stereochemistry affects the properties and functions of amino acids.
Amino Acid Structure Table
| Amino Acid | Structure | R Group |
|---|---|---|
| Glycine | H | |
| Alanine | CH3 | |
| Valine | CH(CH3)2 | |
| Leucine | (CH2)3CH3 | |
| Isoleucine | CH(CH3)CH2CH3 |
By familiarizing yourself with the structure of amino acids and their unique R groups, you will have a solid foundation for further exploration of their properties, functions, and classifications.
All 20 Amino Acids: Charged, Polar, and Nonpolar
When it comes to understanding amino acids, classification is key. The 20 common amino acids can be grouped into three categories based on their properties: charged, polar, and nonpolar.
Charged Amino Acids
Charged amino acids carry an electric charge due to their side chains. There are two negatively charged amino acids: glutamate and aspartate. On the other hand, three amino acids have positively charged side chains: arginine, histidine, and lysine.
Polar Amino Acids
Polar amino acids are hydrophilic, meaning they interact readily with water. These amino acids include asparagine, aspartate, serine, glutamine, threonine, glutamate, and tyrosine. Their polar nature makes them soluble in water and important for various cellular processes.
Nonpolar Amino Acids
Nonpolar amino acids are hydrophobic, meaning they repel water. These amino acids include alanine, phenylalanine, glycine, proline, isoleucine, tryptophan, leucine, valine, methionine, and cysteine. Their hydrophobic nature allows them to interact with nonpolar environments, such as the interior of proteins.
Understanding the classification of amino acids is essential for their memorization. It helps to group them based on their properties and functions within biological systems.
Let’s take a closer look at each category and the amino acids they contain:

Carbon Skeleton and Amino Acid Classification
Amino acids are the building blocks of proteins and have a common carbon skeleton. This skeleton consists of an amino group (NH2), a carboxylic acid group (COOH), and an R group attached to a central carbon atom. The R group is what differentiates each amino acid and gives it unique properties.
The classification of amino acids is based on their R group and determines their hydrophobic or hydrophilic nature. Hydrophobic amino acids have non-polar R groups and tend to reside in the cores of proteins. On the other hand, hydrophilic amino acids have polar R groups and prefer to be exposed to water.
Understanding the carbon skeleton and classification of amino acids is crucial for their memorization. Let’s take a closer look at this classification:
Hydrophobic Amino Acids
