People with Treacher Collins syndrome often have eyes that slant downward, sparse eyelashes, and a notch in the lower eyelids called an eyelid coloboma. Some affected individuals have additional eye abnormalities that can lead to vision loss.
Pantothenic acid, also called pantothenate or vitamin B5 (a B vitamin), is a water-soluble vitamin. For many animals, pantothenic acid is an essential nutrient.Animals require pantothenic acid to synthesize coenzyme-A (CoA), as well as to synthesize and metabolize proteins, carbohydrates, and fats.hen found in foods, most pantothenic acid is in the form of CoA or acyl carrier protein (ACP). For the intestinal cells to absorb this vitamin, it must be converted into free pantothenic acid. Within the lumen of the intestine, CoA and ACP are hydrolyzed into 4'-phosphopantetheine.
A derivative of pantothenic acid called pantethine is being studied to see if it may help lower cholesterol levels in the body. Vitamin B5 deficiency is rare, but may include symptoms such as fatigue, insomnia, depression, irritability, vomiting, stomach pains, burning feet, and upper respiratory infections.antothenic acid gets its name from the Greek root pantos, meaning everywhere, because it is available in a wide variety of foods. However, the vitamin B5 in foods is lost during processing. Fresh meats, vegetables, and whole unprocessed grains have more vitamin B5 than refined, canned, and frozen food.
