Photosynthetic pigmentA photosynthetic pigment (accessory pigment; chloroplast pigment; antenna pigment) is a pigment that is present in chloroplasts or photosynthetic bacteria and captures the light energy necessary for photosynthesis. List of photosynthetic pigments (in order of increasing polarity): Carotene: an orange pigment Xanthophyll: a yellow pigment Phaeophytin a: a gray-brown pigment Phaeophytin b: a yellow-brown pigment Chlorophyll a: a blue-green pigment Chlorophyll b: a yellow-green pigment Chlorophyll a is the most common of the six, present in every plant that performs photosynthesis.
JeromeJerome (dʒəˈroʊm; Eusebius Sophronius Hieronymus; Εὐσέβιος Σωφρόνιος Ἱερώνυμος; 342–347 – 30 September 420), also known as Jerome of Stridon, was a Catholic priest, confessor, theologian, and historian; he is commonly known as Saint Jerome. Jerome was born at Stridon, a village near Emona (now Ljubljana, capital of Slovenia) on the border of Dalmatia and Pannonia. He is best known for his translation of the Bible into Latin (the translation that became known as the Vulgate) and his commentaries on the whole Bible.
AcidAn acid is a molecule or ion capable of either donating a proton (i.e. hydrogen ion, H+), known as a Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the proton donors, or Brønsted–Lowry acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Arrhenius acids. Brønsted and Lowry generalized the Arrhenius theory to include non-aqueous solvents.
Phenolic content in wineThe phenolic content in wine refers to the phenolic compounds—natural phenol and polyphenols—in wine, which include a large group of several hundred chemical compounds that affect the taste, color and mouthfeel of wine. These compounds include phenolic acids, stilbenoids, flavonols, dihydroflavonols, anthocyanins, flavanol monomers (catechins) and flavanol polymers (proanthocyanidins). This large group of natural phenols can be broadly separated into two categories, flavonoids and non-flavonoids.
BASICBASIC (Beginners' All-purpose Symbolic Instruction Code) is a family of general-purpose, high-level programming languages designed for ease of use. The original version was created by John G. Kemeny and Thomas E. Kurtz at Dartmouth College in 1963. They wanted to enable students in non-scientific fields to use computers. At the time, nearly all computers required writing custom software, which only scientists and mathematicians tended to learn.
Jerome K. JeromeJerome Klapka Jerome (2 May 1859 – 14 June 1927) was an English writer and humourist, best known for the comic travelogue Three Men in a Boat (1889). Other works include the essay collections Idle Thoughts of an Idle Fellow (1886) and Second Thoughts of an Idle Fellow; Three Men on the Bummel, a sequel to Three Men in a Boat; and several other novels. Jerome was born in Walsall, England, and, although he was able to attend grammar school, his family suffered from poverty at times, as did he as a young man trying to earn a living in various occupations.
.ch.ch is the country code top-level domain (ccTLD) for Switzerland in the Domain Name System of the Internet. Made available in 1987, only two years after .com, it is administered by SWITCH Information Technology Services. The domain ch, as with other ccTLDs, is based on the ISO 3166-2 code for Switzerland derived from Confoederatio Helvetica (Helvetic Confederation), the Latin name for the country, which was used because of its neutrality with regard to the four official languages of Switzerland.
Acid dissociation constantIn chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted K_a) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction HA A^- + H^+ known as dissociation in the context of acid–base reactions. The chemical species HA is an acid that dissociates into , the conjugate base of the acid and a hydrogen ion, .
BetalainBetalains are a class of red and yellow tyrosine-derived pigments found in plants of the order Caryophyllales, where they replace anthocyanin pigments. Betalains also occur in some higher order fungi. They are most often noticeable in the petals of flowers, but may color the fruits, leaves, stems, and roots of plants that contain them. They include pigments such as those found in beets. The name "betalain" comes from the Latin name of the common beet (Beta vulgaris), from which betalains were first extracted.
Saint-JérômeSaint-Jérôme (sɛ̃ ʒeʁom) (2021 population 80,213) is a suburban city located about northwest of Montreal on the Rivière du Nord. It is part of the North Shore sector of Greater Montreal. It is a gateway to the Laurentian Mountains and its resorts via the Autoroute des Laurentides. The town is named after Saint Jerome (ca. 347 – September 30, 420), a church father best known as the translator of the Bible from Greek and Hebrew into Latin. His translation is known as the Vulgate.
MoleculeA molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion. In quantum physics, organic chemistry, and biochemistry, the distinction from ions is dropped and molecule is often used when referring to polyatomic ions. A molecule may be homonuclear, that is, it consists of atoms of one chemical element, e.g. two atoms in the oxygen molecule (O2); or it may be heteronuclear, a chemical compound composed of more than one element, e.
