Amino Acid Classification Quiz

Amino acids containing two carbon atoms in their backbone.

Amino acids containing three carbon atoms in their backbone. Examples include Alanine, Serine, Cysteine, Phenylalanine, Tyrosine, Tryptophan, and Histidine.

Amino acids containing four carbon atoms in their backbone. Examples include Methionine and Threonine.

Amino acids containing five carbon atoms in their backbone. Examples include Arginine and Valine.

Amino acids containing six carbon atoms in their backbone. Examples include Lysine, Leucine, and Isoleucine.

An amino acid with a cyclic structure, characterized by a secondary amine group.

Amino acids with carboxyl groups (-COOH) in their side chains, making them acidic. Examples include Glutamic acid and Aspartic acid.

Amino acids with basic side chains with positively charged amine groups. Examples include Lysine, Arginine, and Histidine.

Amino acids containing sulfur atoms in their side chains. Examples include Cysteine and Methionine.

Amino acids having hydroxyl groups (-OH). They are involved in phosphorylation and other metabolic processes. Examples include Serine, Threonine, and Tyrosine.

Amino acids with aromatic rings in their structures, allowing them to absorb UV light. Examples include Phenylalanine, Tyrosine, and Tryptophan.

Amino acids containing a ring structure with nitrogen atoms. Examples include Histidine, Proline, and Tryptophan.

All amino acids that do not have a ring structure or branched side chains. These amino acids are typically found in the interior of proteins.

Amino acids with branched carbon chains in their side chains. Examples include Valine, Leucine, and Isoleucine.

Amino acids containing the amide group (CONH2). Examples are Glutamine and Asparagine.

Amino acids that cannot be synthesized by the human body and must be obtained through diet.

Amino acids that can be synthesized by the human body, but may also be obtained through diet. These are important for growth, development, and various physiological functions.

Amino acids that can be synthesized by the human body. These are not required in the diet.

Amino acids that are exclusively broken down into ketone bodies. This includes Leucine and Lysine.

Amino acids that are broken down into both glucose and ketone bodies. This includes Isoleucine, Tyrosine, Phenylalanine, and Tryptophan.

Amino acids that are primarily broken down into glucose. All other amino acids except the ketogenic and glucogenic and ketogenic amino acids fall into this category.

The ability of amino acids to dissolve in polar solvents such as water and alcohol.

Amino acids are generally colorless, except for aromatic amino acids. Aromatic amino acids absorb ultraviolet light at a wavelength of 280 nm.

The characteristic of amino acids to act as both an acid (proton donor) and a base (proton acceptor).

The specific pH value at which an amino acid exists in a neutral form with no net charge.

The group of amino acids that are attracted to and readily dissolve in water. They are polar in nature, possessing charged or hydrophilic side chains.

The group of amino acids that are repelled by water and tend to cluster away from it in aqueous environments. They are non-polar and hydrophobic in nature, possessing uncharged and hydrophobic side chains.

A classification based on the number of carbon atoms in the amino acid's backbone structure.

A classification system that categorizes amino acids based on specific structural features they possess. Examples include Imino Acid, Aromatic Amino Acids, and Sulfur Containing Amino Acids.

A system that categorizes amino acids based on their polarity, which determines their interactions with water and other molecules.

A classification system that categorizes amino acids based on their essentiality for human health. Essential amino acids must be obtained from the diet, while non-essential amino acids can be synthesized by the body.

A classification system that groups amino acids based on their metabolic fates - whether they are broken down into glucose, ketone bodies, or both.
