In the
previous post, we talked about how Argininosuccinate
Lyase is an enzyme in the urea cycle that catalyzes the reversible argininosuccinate, producing
amino acid arginine and dicarboxylic acid fumarate.
So what exactly is Arginine?
(structure of L-Arginine)
Arginine in its 'L' form is a
semi-essential α-amino
acid. Because L-arginine is involved in
many metabolic processes, it is significant
for the execution of many physiological processes. These processes include
hormone secretion, an increase in growth hormone output, the removal of toxic
waste products from the body, and immune system defenses.
In the body, the amino acid arginine is a precursor of nitric
oxide (NO). Nitric oxide is a powerful neurotransmitter that helps blood
vessels relax and also improves circulation. it is often used for treating conditions such as chest cramping
[angina], high blood pressure, heart disease, and sexual dysfunction. Arginine
is also used in the treatment of male and female infertility.
There are also other functions of Arginine such as:
- Helping to reduce insulin resistance and increase glucose tolerance and insulin sensitivity in type 2 diabetes mellitus
- Amino acids supplement, such as Arginine is able to detoxify high level of ammonia as part of the urea cycle
- Arginine supports the production of collagen and is therefore an important contributor to bone growth
Even though the body normally makes enough of it, supplementation is sometimes needed. As our body is not able to produce sufficient amount of Arginine, it is important to consume food high in Arginine.
Here are some examples of food that are high in Arginine:
Here are some examples of food that are high in Arginine:
- Nut
- Spinach and Lentils
- Whole Grains
- Red Meat
- Seafood
- Soy
- Eggs
