Proline
Proline (symbol Pro or P) is an organic acid classed as a proteinogenic amino acid (used in the biosynthesis of proteins), although it does not contain the amino group -NH2 but is rather a secondary amine. The secondary amine nitrogen is in the protonated form (NH2+) under biological conditions, while the carboxyl group is in the deprotonated −COO− form. The "side chain" from the α carbon connects to the nitrogen forming a pyrrolidine loop, classifying it as a aliphatic amino acid.
Staple food
A staple food, food staple, or simply staple, is a food that is eaten often and in such quantities that it constitutes a dominant portion of a standard diet for an individual or a population group, supplying a large fraction of energy needs and generally forming a significant proportion of the intake of other nutrients as well. For humans, a staple food of a specific society may be eaten as often as every day or every meal, and most people live on a diet based on just a small variety of food staples.
Malabsorption
Malabsorption is a state arising from abnormality in absorption of food nutrients across the gastrointestinal (GI) tract. Impairment can be of single or multiple nutrients depending on the abnormality. This may lead to malnutrition and a variety of anaemias. Normally the human gastrointestinal tract digests and absorbs dietary nutrients with remarkable efficiency. A typical Western diet ingested by an adult in one day includes approximately 100 g of fat, 400 g of carbohydrate, 100 g of protein, 2 L of fluid, and the required sodium, potassium, chloride, calcium, vitamins, and other elements.
Sauerkraut
Sauerkraut (ˈsaʊ.ərˌkraʊt; ˈzaʊ.ɐˌkʁaʊt, sour cabbage) is finely cut raw cabbage that has been fermented by various lactic acid bacteria. It has a long shelf life and a distinctive sour flavor, both of which result from the lactic acid formed when the bacteria ferment the sugars in the cabbage leaves. Although it is considered a national dish in Germany and is known under its German name in English-speaking countries, it did not originate in Germany and is also a traditional and ubiquitous dish in Central and Eastern Europe.
Ferdinand Magellan
Ferdinand Magellan (məˈgɛlən or məˈdʒɛlən ; Fernão de Magalhães, fɨɾˈnɐ̃w dɨ mɐɣɐˈʎɐ̃jʃ; Fernando de Magallanes, feɾˈnando ðe maɣaˈjanes; 1480 – 27 April 1521) was a Portuguese explorer best known for having planned and led the 1519 Spanish expedition to the East Indies across the Pacific Ocean to open a maritime trade route, during which he discovered the interoceanic passage thereafter bearing his name and achieved the first European navigation to Asia via the Pacific.
Hydroxylation
In chemistry, hydroxylation can refer to: (i) most commonly, hydroxylation describes a chemical process that introduces a hydroxyl group () into an organic compound. (ii) the degree of hydroxylation refers to the number of OH groups in a molecule. The pattern of hydroxylation refers to the location of hydroxy groups on a molecule or material. Installing hydroxyl groups into organic compounds can be effected by various metal catalysts. Many such catalysts are biomimetic, i.e.
Vasco da Gama
Vasco da Gama, 1st Count of Vidigueira (ˌvæsku_də_ˈɡɑːmə,_ˈɡæmə; ˈvaʃku ðɐ ˈɣɐ̃mɐ; c. 1460s – 24 December 1524), was a Portuguese explorer and the first European to reach India by sea. His initial voyage to India by way of Cape of Good Hope (1497–1499) was the first to link Europe and Asia by an ocean route, connecting the Atlantic and the Indian oceans. This is widely considered a milestone in world history, as it marked the beginning of a sea-based phase of global multiculturalism.
Public health
Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals". Analyzing the determinants of health of a population and the threats it faces is the basis for public health. The public can be as small as a handful of people or as large as a village or an entire city; in the case of a pandemic it may encompass several continents.
Lysine
Lysine (symbol Lys or K) is an α-amino acid that is a precursor to many proteins. It contains an α-amino group (which is in the protonated −NH3+ form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a side chain lysyl ((CH2)4NH2), classifying it as a basic, charged (at physiological pH), aliphatic amino acid. It is encoded by the codons AAA and AAG. Like almost all other amino acids, the α-carbon is chiral and lysine may refer to either enantiomer or a racemic mixture of both.
