Flashcards

Conditionally essential amino acid in humans

An amino acid that is normally non-essential but becomes essential under certain circumstances or conditions, such as illness or stress.

Non-essential amino acid

An amino acid that does not need to be consumed through the diet as it can be synthesized by the human body in sufficient amounts.

Essential amino acid

An amino acid that cannot be synthesized by the body and must be obtained through the diet.

Example of an essential amino acid

An amino acid required by the body that can't be created or made within the body itself and must be consumed through food or supplements.

Study Notes

Essential and Non-Essential Amino Acids

Arginine is considered conditionally essential in the human diet, meaning it can be synthesized in the body but not in sufficient quantities, especially in times of illness or stress.
Alanine is considered non-essential (dispensable) in humans, meaning it can be synthesized in the body from other amino acids and does not need to be obtained through the diet.
Tryptophan is an example of an essential amino acid, which cannot be synthesized in the body and must be obtained through the diet or supplements.
Arginine cannot be synthesized in sufficient quantities in the body and is therefore considered conditionally essential, especially in times of illness or stress.
Selenocysteine is considered the 21st amino acid, meaning it is not one of the standard 20 amino acids commonly found in proteins but is still important for human health.
