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 ...
Folic acid, chemically described as pteroylmonoglutamic acid, is another vitamer of vitamin B 9. Though rarely found in minimally processed foods, it is the primary form of vitamin B 9 added to fortified foods and many dietary supplements. [3] Folic acid and food folates are absorbed and metabolized by different pathways.
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.
Fenugreek ( / ˈfɛnjʊɡriːk /; Trigonella foenum-graecum) is an annual plant in the family Fabaceae, with leaves consisting of three small obovate to oblong leaflets. It is cultivated worldwide as a semiarid crop. Its leaves and seeds are common ingredients in dishes from the Indian subcontinent, and have been used as a culinary ingredient ...
Biodiversity and drugs. Biodiversity plays a vital role in maintaining human and animal health because numerous plants, animals, and fungi are used in medicine to produce vital vitamins, painkillers, antibiotics, and other medications. [1] [2] [3] Natural products have been recognized and used as medicines by ancient cultures all around the ...
