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.
Description. The almond is a deciduous tree growing to 3–4.5 metres (10–15 feet) in height, [ 4][ 7] with a trunk of up to 30 centimetres (12 inches) in diameter. The young twigs are green at first, becoming purplish where exposed to sunlight, then gray in their second year.
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 ...
Nuts are a good source of protein, but they shouldn't be your only one — plus other things experts want you to know about this plant-based snack. Dietitians debunk 7 myths about nuts, including ...
Selenium, which is an essential element for animals and prokaryotes and is a beneficial element for many plants, is the least-common of all the elements essential to life. [3] [61] Selenium acts as the catalytic center of several antioxidant enzymes, such as glutathione peroxidase, [10] and plays a wide variety of other biological roles.
Selenomethionine (SeMet) is a naturally occurring amino acid. The L -selenomethionine enantiomer is the main form of selenium found in Brazil nuts, cereal grains, soybeans, and grassland legumes, while Se -methylselenocysteine, or its γ-glutamyl derivative, is the major form of selenium found in Astragalus, Allium, and Brassica species.

This arrangement means that the root nodules are sources of nitrogen for legumes, making them relatively rich in plant proteins. All proteins contain nitrogenous amino acids. Nitrogen is therefore a necessary ingredient in the production of proteins. Hence, legumes are among the best sources of plant protein.
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 ...
