largest part of brain
deficiency of vitamin A
Answers
Explanation:
Vitamin A is required for the formation of rhodopsin, a photoreceptor pigment in the retina (see table Sources, Functions, and Effects of Vitamins). Vitamin A helps maintain epithelial tissues and is important for lysosome stability and glycoprotein synthesis.
Dietary sources of preformed vitamin A include fish liver oils, liver, egg yolks, butter, and vitamin A–fortified dairy products. Beta-carotene and other provitamin carotenoids, contained in green leafy and yellow vegetables, carrots, and deep- or bright-colored fruits, are converted to vitamin A. Carotenoids are absorbed better from vegetables when they are cooked or homogenized and served with some fat (eg, oils). Normally, the liver stores 80 to 90% of the body’s vitamin A. To use vitamin A, the body releases it into the circulation bound to prealbumin (transthyretin) and retinol-binding protein.
Retinol activity equivalents (RAE) were developed because provitamin A carotenoids have less vitamin A activity than preformed vitamin A; 1 mcg retinol = 3.33 units.
