With few exceptions, like some vitamins from B-complex, hypervitaminosis usually occurs with the fat-soluble vitamins A and D, which are stored, respectively, in the liver and fatty tissues of the body. These vitamins build up and remain for a longer time in the body than water-soluble vitamins. [2] Conditions include: Hypervitaminosis A
Vitamins are classified as either water-soluble or fat-soluble. In humans there are 13 vitamins: 4 fat-soluble (A, D, E, and K) and 9 water-soluble (8 B vitamins and vitamin C). Water-soluble vitamins dissolve easily in water and, in general, are readily excreted from the body, to the degree that urinary output is a strong predictor of vitamin ...
Pantothenic acid is a water-soluble vitamin, one of the B vitamins. It is synthesized from the amino acid β-alanine and pantoic acid (see biosynthesis and structure of coenzyme A figures). Unlike vitamin E or vitamin K , which occurs in several chemically related forms known as vitamers , pantothenic acid is only one chemical compound.
B vitamins are a class of water-soluble vitamins that play important roles in cell metabolism and synthesis of red blood cells. [1] [2] They are a chemically diverse class of compounds. [1] Dietary supplements containing all eight are referred to as a vitamin B complex.
Riboflavin, also known as vitamin B 2, is a water-soluble vitamin and is one of the B vitamins. [3] [4] [5] Unlike folate and vitamin B 6, which occur in several chemically related forms known as vitamers, riboflavin is only one chemical compound.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The lipid components of lipoproteins are insoluble in water. However, because of their detergent-like (amphipathic) properties, apolipoproteins and other amphipathic molecules (such as phospholipids) can surround the lipids, creating a lipoprotein particle that is itself water-soluble, and can thus be carried through body fluids (i.e., blood ...
Ascorbic acid (Vitamin C) – antioxidant (water-soluble) Ascorbyl palmitate – antioxidant (fat soluble) Ascorbyl stearate – antioxidant (fat soluble) Aspartame – artificial sweetener; Aspartame-acesulfame salt – artificial sweetener; Astaxanthin – color; Avocado oil – used a substitute for olive oil. Also used in cosmetics and skin ...
