Glycine, a multipurpose substance for the brain

Glycine acts as a neurotransmitter and also as an amino acid in the brain. We do not know it, we do not even perceive it, but this multipurpose substance works continuously to promote well-being. It does this in many ways, but suffice it to say just as an example that, without it, we would not have a restful night’s sleep.

As we often say, The human being and in essence every living being is pure chemistry. Each and every one of the processes that occur inside us are mediated by molecules, neurotransmitters, hormones, amino acids, etc. Thus, among all those substances that guarantee our balance and homeostasis, there is one that stands out for its great functionality and relevance.

Indeed, glycine is an essential chemical element for us. Thus, and although names such as serotonin, dopamine or endorphins are better known to the vast majority, it is time for us to keep this little one in mind. key compound that facilitates communication between neurons.

Let’s dig a little deeper.

Wisteria: what it is and what it does for us

Glycine is an amino acid that is present in the proteins of all living beings. As a curiosity, it should be said that it is the smallest amino acid and that, in addition, it also acts as a neurotransmitter. The latter is what gives them relevance and interest at all levels.

It flows through the blood and crosses the blood-brain barrier, finally reaching the entire central nervous system. When it does, when it reaches the brain, becomes attached to a series of synaptic receptors and then orchestrates a series of biological processes.

It is also interesting to know that the body produces glycine on its own, however, We also consume it through any food rich in protein., such as meat of all types, fish, eggs, dairy products and legumes. Likewise, there are those who choose to reinforce their levels through dietary supplements for various purposes, such as regulating sleep.

Let us therefore know what functions glycine has and everything it can do for us.

Facilitates communication between neurons

When glycine adheres to its receptors in the central nervous system, a series of essential changes are triggered for the proper functioning of neurons. What it does is facilitate the entry of chloride ions into the nerve cell.

Something like this drives the electrical impulse, so that this effect travels to many other neurons through the synaptic clefts, giving way to communication between them.

Regulates movements

Glycine acts as an activating neurotransmitter, but also as an inhibitory molecule. This last function is decisive on the motor level. For example, let’s imagine nervous system ordering the body to start movingto run because you have to cross that zebra crossing before it turns red.

This sequence is driven by numerous neurotransmitters, but a large part of them work by stimulating, that is, making it easier for that action, that movement, to get started. Now, it is also decisive that this movement ceases and for this we have inhibitory neurotransmitters: glycine is one of them.

Regenerates tissues

This fact is interesting, collagen, that protein in the form of fibers that is responsible for uniting connective tissues (muscles, tendons, ligaments, skin, bones, cartilage, etc.) is made up of 4 amino acids, one of them being glycine. . It is so relevant that, in fact, it is the most abundant amino acid in the skin and is key to regenerating tissues.

Facilitates embryonic brain development

In research carried out at the University of Hasselt, Belgium, they highlight the role of glycine as that essential molecule and decisive during the first months of fetal brain development.

Later, and during the first years of the child’s life, it would also be key to all the changes and processes that the brain experiences in those early stages.

Glycine “relaxes neurons” and facilitates rest

Glycine performs a very similar function to GABA, it acts as a relaxant and as an inhibitor of the central nervous system. This task is decisive in reducing, for example, states of stress and anxiety. Nevertheless, Where it is most decisive is in facilitating night rest. It does this in several ways:

Reduces body temperature. Promotes deep, sustained sleep throughout the hours. Promotes muscle relaxation. Helps us “spend” more time in the REM phase of sleep.

Capture of visual and auditory stimuli

Another decisive and interesting function of glycine is the following. Thanks to it, the stimuli we receive from the ears and eyes can reach the brain. This multipurpose neurotransmitter facilitates that connection and those electrical impulses.

Promotes your cognitive functions

Remember what you read, think more reflectively, have a good ability to focus attention, make smarter decisions… All of these cognitive processes are mediated by glycine when it acts as a neurotransmitter in the central nervous system. Thanks to it, the connections between neurons are enhanced to optimize these processes that are so decisive in our daily lives.
