Non-Essential Amino Acids: Definition and Functions

Definition: Non essential amino acids are amino acids that can be produced in our body. Their uses and functions in our body are equally as important as the limiting amino acids. The difference is that those kind of amino acids can be found in our food.

Functions of non-essential amino acids

The following list includse the 12 non-essential amino acids. Included is a some of the functions and benefits and side effects (if any) of the amino acids.

Alanine: Removes toxic substances released from breakdown of muscle protein during intensive exercise. Side effects: Excessive alanine level in the body is associated with chronic fatigue.

Cysteine: Component of protein type abundant in nails, skin and hair. It acts as antioxidant (free radical scavenger), and has synergetic effect when taken with other antioxidants such as vitamin E and selenium.

Cystine: The same as cysteine, it aids in removal of toxins and formation of skin.

Glutamine: Promotes healthy brain function. It is also necessary for the synthesis of RNA and DNA molecules.

Glutathione: Is antioxidant and has anti-aging effect. It is useful in removal of toxins.

Glycine: Component of skin and is beneficial for wound healing. It acts as neurotransmitter. The side effect of high level glycine in the body is that it may cause fatigue.

Histidine: Important for the synthesis of red and white blood cells. It is a precursor for histamine which is good for sexual arousal. Improve blood flow. Side effects of high dosage of histidine include stress and anxiety.

Serine: Constituent of brain proteins and aids in the synthesis of immune system proteins. It is also good for muscle growth. Read more...

Taurine: Necessary for proper brain function and synthesis of amino acids. It is important in the assimilation of mineral nutrients such as magnesium, calcium and potassium.

Threonine: Balances protein level in the body. It promotes immune system. It is also beneficial for the synthesis of tooth enamel and collagen. Read more...

Asparagine: It helps promote equilibrium in the central nervous system—aids in balancing state of emotion.

Apartic acid: Enhances stamina, aids in removal of toxins and ammonia from the body, and beneficial in the synthesis of proteins involved in the immune system. Read more..

Proline: plays role in intracellular signalling.

L-arginine: plays role in blood vessel relaxation, stimulating and maintaining erection in men, production of ejaculate, and removal of excess ammonia from the body. Read more...
