Selenium in biology. Selenocysteine is the main organic molecule involving selenium in humans. Selenium is an essential micronutrient for animals, though it is toxic in large doses. In plants, it sometimes occurs in toxic amounts as forage, e.g. locoweed. Selenium is a component of the amino acids selenocysteine and selenomethionine.
Plant nutrition. 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.
Wheatgrass is a source of potassium, dietary fiber, vitamin A, vitamin C, vitamin E (alpha tocopherol), vitamin K, thiamin, riboflavin, niacin, vitamin B6, pantothenic acid, iron, zinc, copper, manganese, and selenium. It is also a good source of protein, with up to 8 grams per ounce if consumed in powder form or around 1 g in a "shot" of juice.
Despite their name, peanuts are actually a legume(in the same family as beans), as opposed to a nut like almonds or pecans. However, even though peanuts are not technically nuts, they contain many ...
Selenocysteine (symbol Sec or U, [ 4] in older publications also as Se-Cys) [ 5] is the 21st proteinogenic amino acid. Selenoproteins contain selenocysteine residues. Selenocysteine is an analogue of the more common cysteine with selenium in place of the sulfur . Selenocysteine is present in several enzymes (for example glutathione peroxidases ...
Psyllium ( / ˈsɪliəm / ), or ispaghula ( / ˌɪspəˈɡuːlə / ), is the common name used for several members of the plant genus Plantago whose seeds are used commercially for the production of mucilage. Psyllium is mainly used as a dietary fiber to relieve symptoms of both constipation and mild diarrhea, and occasionally as a food ...
Pine nuts, also called piñón (Spanish:), pinoli (Italian: [piˈnɔːli]), or pignoli, are the edible seeds of pines (family Pinaceae, genus Pinus).According to the Food and Agriculture Organization, only 29 species provide edible nuts, while 20 are traded locally or internationally [1] owing to their seed size being large enough to be worth harvesting; in other pines, the seeds are also ...
Selenoprotein. In molecular biology a selenoprotein is any protein that includes a selenocysteine (Sec, U, Se-Cys) amino acid residue. Among functionally characterized selenoproteins are five glutathione peroxidases (GPX) and three thioredoxin reductases, (TrxR/TXNRD) which both contain only one Sec. [ 1] Selenoprotein P is the most common ...
