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 ...
In chemistry, a zwitterion (/ ˈ t s v ɪ t ə ˌ r aɪ ə n / TSVIT-ə-ry-ən; from German Zwitter 'hermaphrodite'), also called an inner salt or dipolar ion, [1] is a molecule that contains an equal number of positively and negatively charged functional groups. [2] 1,2-dipolar compounds, such as ylides, are sometimes excluded from the ...
Vitamin B 12, also known as cobalamin, is a water-soluble vitamin involved in metabolism. [2] It is one of eight B vitamins . It is required by animals, which use it as a cofactor in DNA synthesis , and in both fatty acid and amino acid metabolism . [ 3 ]
Riboflavin deficiency is usually found together with other nutrient deficiencies, particularly of other water-soluble vitamins. [3] A deficiency of riboflavin can be primary (i.e. caused by poor vitamin sources in the regular diet) or secondary, which may be a result of conditions that affect absorption in the intestine.
Fundamentally, the difference between these two types of fibers relates to how the fiber reacts with water. “Soluble fibers can dissolve in water and insoluble fibers do not dissolve in water ...
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.
Because you can get too many.
B vitamins are commonly added to energy drinks, many of which have been marketed with large amounts of B vitamins. [7] Because they are soluble in water, excess B vitamins are generally readily excreted, although individual absorption, use and metabolism may vary. [7]
