The levorotator rotates counterclockwise.
Levógyro is a turn to the left . A brief analysis of the etymology of this masculine adjective (which can also be used as a noun) allows us to recognize its Latin components laevos ("left") and girare ("turn"). You can also say that something rotates "left-handedly."
Counterclockwise
Levógyro refers to that which rotates in the opposite direction to clockwise . This means that a turn is left-handed if it traces its path counterclockwise .
The opposite of a left-handed person is a right-handed person . Turning in the same direction as clockwise is described as right-handed.
We can find the idea of left-handedness in different contexts. In the field of botany , we speak of left-handed movement with respect to the direction that, when advancing to the left, the tendrils of the guiding plants follow.
Left-handed snails
Left-handed snails are those whose shells have a spiral that develops counterclockwise , which means that their opening is directed to the left. This characteristic is due to the spatial arrangement of the proteins that are responsible for the formation of the shell, which are organized in a helical manner. These specimens are colloquially known as left-handed .
It is important to note that right-handed snails (which have a spiral that develops in the opposite direction, with the opening directed to the right) are much more common. That is why levorotatory snails are exceptional and of great interest to zoological experts.
In nature, both left-handed and right-handed snails can be found in different species, and in some cases the proportion of one form or another may vary depending on the population or habitat.
The orientation of the spiral of the shell of snails plays an important role in natural selection, as it can influence the animal's ability to protect itself from predators or to access certain foods or habitats. Additionally, the presence of left-handed snails in some species may be a useful trait for taxonomic identification and classification .
Left-handed substance
Left-handed substance, also known as L-isomer , refers to a specific form of molecule that rotates polarized light to the left. This optical property is due to the spatial arrangement of the atoms that make up the molecule and is used in chemistry to distinguish between different isomers.
In contrast, the right-handed substance, also known as the D-isomer , rotates polarized light to the right. These terms are commonly used in the field of organic chemistry , where stereoisomerism plays an important role in understanding the properties and reactions of molecules.
It is important to highlight that the left-handed and right-handed substances have different chemical and physical properties , which can influence their biological activity and their therapeutic use in medicine . Therefore, it is essential to take these differences into account in the research and development of new drugs and chemical compounds.
The serrations on the left-handed barrels of firearms rotate counterclockwise.
firearms
Another use of left-handed rotation refers to the counterclockwise rotation of the serrations (the hollow stripes) of the bore (the interior space) of the barrel of a firearm . In this way, after the shot, the projectile moves rotating on itself. This counterclockwise rotation is due to the direction of the recoil force of the weapon when firing, which directly influences that of the barrel. Note that there are also right-handed firearm barrels, which rotate to the right.
Left-handed barrels are primarily used in portable firearms, such as pistols and assault rifles , and are also used in some tank guns and other armored vehicles . Although left-handed guns are less common than right-handed guns, they are considered no more or less effective in terms of accuracy and firepower.
