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 ...
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.
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 ...
Antinutrient. Phytic acid ( deprotonated phytate anion in the picture) is an antinutrient that interferes with the absorption of minerals from the diet. Antinutrients are natural or synthetic compounds that interfere with the absorption of nutrients. [1] Nutrition studies focus on antinutrients commonly found in food sources and beverages.
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.
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 ...
Procyanidin. Epicatechin (EC), one of the building blocks of procyanidins. Cyanidin, the anthocyanidin produced when procyanidin are depolymerized under oxidative conditions. Procyanidins are members of the proanthocyanidin (or condensed tannins) class of flavonoids. They are oligomeric compounds, formed from catechin and epicatechin molecules.
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.
