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. Individual B vitamins are referred to by B-number or by chemical name ...
Thiamine, also known as thiamin and vitamin B 1, is a vitamin, an essential micronutrient for humans and animals. [3] [4] It is found in food and commercially synthesized to be a dietary supplement or medication. [1] [5] Phosphorylated forms of thiamine are required for some metabolic reactions, including the breakdown of glucose and amino ...
Allithiamine. Allithiamine ( thiamine allyl disulfide or TAD) is a lipid -soluble form of vitamin B 1 which was discovered in garlic ( Allium sativum) in the 1950s along with its homolog prosultiamine. [ 1] They were both investigated for their ability to treat Wernicke–Korsakoff syndrome and beriberi better than thiamine.
Benfotiamine. Benfotiamine ( rINN, or S-benzoylthiamine O-monophosphate) is a synthetic, fat-soluble, S -acyl derivative of thiamine (vitamin B1) that is approved in some countries as a medication or dietary supplement to treat diabetic sensorimotor polyneuropathy. Benfotiamine was developed in late 1950s in Japan. [ 1][ 2]
In Wikidata. Vitamins are organic molecules (or a set of closely related molecules called vitamers) that are essential to an organism in small quantities for proper metabolic function. Essential nutrients cannot be synthesized in the organism in sufficient quantities for survival, and therefore must be obtained through the diet.
All six naturally occurring vitamers of vitamin B 6 are found in foods. [3] Pyridoxine, along with its phosphorylated form, pyridoxine-5'-phosphate, are primarily found in plant-based foods. Pyridoxine is the most stable vitamer of vitamin B 6. Pyridoxine glucoside is a related vitamer that is also found in some plant-based foods.
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite. This is in accordance with Justus von ...
Thiamine deficiency. Thiamine deficiency is a medical condition of low levels of thiamine (vitamin B 1 ). [ 1] A severe and chronic form is known as beriberi. [ 1][ 7] The name beriberi was possibly borrowed in the 18th century from the Sinhalese phrase බැරි බැරි (bæri bæri, “I cannot, I cannot”), owing to the weakness ...
