Some alkaloids can produce developmental defects in the offspring of animals that consume but cannot detoxify the alkaloids. One example is the alkaloid cyclopamine, produced in the leaves of corn lily. During the 1950s, up to 25% of lambs born by sheep that had grazed on corn lily had serious facial deformations.
Ephedrine may decrease motion sickness, but it has mainly been used to decrease the sedating effects of other medications used for motion sickness. [21] [22] Ephedrine is also found to have quick and long-lasting responsiveness in congenital myasthenic syndrome in early childhood and also even in adults with a novel COLQ mutation. [23]
Phytochemistry is the study of phytochemicals, which are chemicals derived from plants.Phytochemists strive to describe the structures of the large number of secondary metabolites found in plants, the functions of these compounds in human and plant biology, and the biosynthesis of these compounds.
Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [ 2 ] Water makes up a large proportion of the total mass ingested as part of a normal diet but it does not provide any nutritional value.
Naturally occurring phenethylamines are organic compounds which may be thought of as being derived from phenethylamine itself that are found in living organisms. Tyramine is a phenethylamine that occurs widely in plants [ 1 ] and animals , and is metabolized by various enzymes , including monoamine oxidases .
Protein occurs in a wide range of food. [11] [12] On a worldwide basis, plant protein foods contribute over 60% of the per capita supply of protein. [9] In North America, animal-derived foods contribute about 70% of protein sources. [12] Insects are a source of protein in many parts of the world. [13]
Plants synthesize certain compounds called secondary metabolites which are not naturally produced by humans but can play vital roles in protection or destruction of human health. One such group of metabolites is phytoestrogens, found in nuts, oilseeds, soy, and other foods. [17] Phytoestrogens are chemicals which act like the hormone estrogen.
Protein production is the biotechnological process of generating a specific protein. It is typically achieved by the manipulation of gene expression in an organism such that it expresses large amounts of a recombinant gene .
