BETA CAROTENE Meaning and
Definition
-
Beta carotene is a naturally occurring pigment and antioxidant belonging to the carotenoid family, which is responsible for imparting the orange and yellow colors in fruits and vegetables. It is considered a precursor of Vitamin A as it can be converted into the active form of the vitamin in the body.
Chemically, beta carotene consists of a chain of 40 carbon atoms, with conjugated double bonds that enable it to absorb light in the visible spectrum. Its structure includes two molecules of retinol, the form of Vitamin A found in animal sources, and therefore the body can cleave the beta carotene molecule into two molecules of Vitamin A when needed.
Beta carotene has gained attention and recognition for its numerous health benefits. As an antioxidant, it helps protect cells from oxidative damage caused by free radicals, thereby reducing inflammation and promoting overall health. It has also been associated with improved immune function, proper vision, and healthy skin. Beta carotene is commonly found in orange and yellow fruits and vegetables such as carrots, sweet potatoes, mangoes, and apricots, as well as leafy greens like spinach and kale.
Supplementing with beta carotene is an option for individuals who have difficulty obtaining adequate amounts through their diet. However, excessive intake of beta carotene through supplements may lead to a benign condition called carotenemia, where the skin takes on a yellow-orange hue. It is important to note that beta carotene supplements should not be considered a replacement for a well-balanced diet rich in various nutrients.
Etymology of BETA CAROTENE
The word "beta carotene" is derived from the Latin words "beta" and "carota".
1. "Beta" comes from the Greek letter "beta", which was derived from the Phoenician letter "beth". The Phoenician letter represented a house or enclosure, while the Greek letter came to represent the second letter of the alphabet. In this context, "beta" refers to the second form of carotene to be discovered and named, following the initial discovery of alpha carotene.
2. "Carota" is the Latin term for "carrot", derived from the Greek word "karoton". This is in reference to the fact that beta carotene is abundantly found in carrots.
Therefore, the word "beta carotene" essentially translates to "second carotene found in carrots" in relation to its discovery and natural source.
