Definition of
counterclockwise
counterclockwise it’s a left turn. 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 I will turn (“spin”). It can also be said that something rotates “counterclockwise”.

Opposite clockwise
Levógiro alludes to what rotates in an anti-clockwise direction. This means that a spin is left-handed if it traces its trajectory in counter-clock wise.
The opposite of left-handed is a dextro-rotatory. A turn in the same direction as clockwise is classified as right-handed.
We can find the idea of left-handed in different contexts. In the field of botany, we speak of left-handed with respect to the direction that, when advancing to the left, the tendrils of the guide plants.

left-handed snails
Left-handed snails are those whose shells have a spiral that develops in sense contrary to the needles of the clock, which means that its 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 fashion. These specimens are colloquially known as left handed.
It is important to point out that the snails Dextrorotatory (having a counter-developing spiral, with the opening directed to the right) are much more common. That’s why left-handed snails are exceptional and of great interest to experts in zoology.
In nature, both left-handed and right-handed snails can be found in different species, and in some cases, the ratio of one way or another can vary depending on the population or habitat.
The orientation The spiral of the shell of snails has an important role in natural selection, since it can influence the ability of the animal to protect itself from its predators or to access certain foods or habitats. Furthermore, the presence of left-handed snails in some species may be a feature useful for identification and taxonomic classification.

left-handed substance
The left-handed substance, also known as L-isomerrefers to a specific shape of molecule that rotates the light polarized 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 dextrorotatory substance, also known as 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 note that the left-handed and right-handed substance have different chemical and physical properties, which may influence its biological activity and its 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.

Firearms
Another use of left-handed refers to the counterclockwise rotation of the rifling (hollow marks) of the bore (interior space) of a barrel. firearm. In this way, after the shot, the projectile It moves by 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 used primarily in portable firearms, such as pistols and assault riflesand are also used in some guns of tanks and other armored vehicles. Although left-handed guns are less common than right-handed ones, they are not considered any more or less effective in terms of accuracy and firepower.
