Vitamin A. Vitamin A was the first fat-soluble vitamin identified (in 1913). Vitamin A comprises the preformed retinoids, plus the precursor forms, the provitamin A carotenoids. Preformed retinoids is a collective term for retinol, retinal, and retinoic acid, all of which are biologically active.etinoids are converted to retinol in the intestines and transported with dietary fat to the liver, where it is stored. A special transport protein, retinolbinding protein (RBP), transports vitamin A from the liver to other tissues. Carotenoids are absorbed intact at a much lower absorption rate than retinol.
Mopar is the parts, service and customer care organization within Fiat Chrysler Automobiles. Mopar also designs and builds a small number of customized vehicles. The name derives from a combination of letters from the words MOtor and PARts.
Today that is a totally different story. Mopar provides quality replacement parts for Dodge, and Chrysler vehicles, as well as producing aftermarket parts for performance on the strip and street legal models. When people think of Mopar, they think of power, performance, and quality. This all began in the early 1950âs when Mopar created the hemispherical engine. This was the beginning of an engineering trend that would turn Mopar into a legacy. They started this trend with the Plymouth and Dodge vehicles, and in 1956, Plymouth began to demand respect from race lovers all over.
