Groups names for

When writing an alkane name, the nonhyphenated prefix iso- is considered part of the alkyl-group name for alphabetizing purposes, but the hyphenated and italicized prefixes sec- and tert- are not. Thus, isopropyl and isobutyl are listed alphabetically under i, but sec-butyl and ferf-butyl are listed under b. 

Addition of sufficient base to give a > 3 to a ferric solution immediately leads to precipitation of a poorly ordered, amorphous, red-brown ferric hydroxide precipitate. This synthetic precipitate resembles the mineral ferrihydrite, and also shows some similarity to the iron oxyhydroxide core of ferritin (see Chapter 6). Ferrihydrite can be considered as the least stable but most reactive form of iron(III), the group name for amorphous phases with large specific surface areas (>340 m2 /g). We will discuss the transformation of ferrihydrite into other more-crystalline products such as goethite and haematite shortly, but we begin with some remarks concerning the biological distribution and structure of ferrihydrite (Jambor and Dutrizac, 1998). 

POLYOLEFIN. A class or group name for thermoplastic polymers derived from simple olefins among the more important are polyethylene, polyproplene, polybutenes, polyisoprene, and their copolymers. Many are produced in the form of fibers. This group comprises the largest tonnage of all thermoplastics produced. 

Cyclamate. Group name for synthetic, nonnutritive sweeteners derived from cyclohexylamine or cyclamic acid. The senes includes sodium, potassium, and calcium cydamates. Cyclamates occur as white crystals, or as white crystalline powders. They are odorless and in dilute solution are about 30 times as sweet as sucrose. The purity of commercially available compounds is approximately 98%. 

UGRANDITE. A group name for the calcium garnet minerals uvarovite,... 

Vitamin K — Fat-soluble vitamin K is a group name for fat-soluble compounds which have in common a methylated naphthoquinone ring structure. Vitamin K is found in nature in two forms - Ki or phylloquinone is found in plants and vitamin K2 or menaquinone can be synthesized by many bacteria. Vitamin K3 (menadione) is a synthetic form of this vitamin. Vitamin K is used... 

Is the group name for a line of bactericides and fungicides used in agricultural, veterinary, cosmetic and pharmaceutical products. They also have application in textiles, detergents, dry wall plaster and industrial deodorants. VANCIDE products are highly effective with relatively low toxicity. 

Sialomucins [Odin (02)] or sialoproteins [Werner (W9)] are another type of mucosubstance found in the stomach. Their carbohydrate moiety is composed of equimolecular amounts of acetylhexosamine (usually galactosamine) and sialic acid. The latter is a group name for several materials derived from the same basic substance, neuraminic acid. In human mucosubstances, the N-acetylneuraminic acid is the main form of sialic acid (FI, F2). In hog stomach, the sialic acid consists of 80%... 

For secondary, tertiary, and quarternary amines, the naming convention is a bit different, but the suffixes are the same. For symmetrical amines, the di" or "tri" prefix is used depending on whether there are 2 or 3 substituents. For example, dipropylamine or triphenylamine. For asymmetric amines, the parent chain gets the -amine suffix. This name is then prefixed with N- (indicating the nitrogen bond) and the substituent group name, for each substituent, using alphabetic order for tertiary amides. For example, N-ethyl-N-methyl-propylamine, not N-methyl-N-ethyl-propylamine. 

Cephalosporlna. Group name for an important group of /3-lactam antibiotics based on the parent skeleton of 7j8-aminocephalosporanic acid (3-acetoxymethyl-7/5-amino-3-cephem-4-carboxyIic acid). 

Historical Berzelius (1837) named the pigment xan-thophyll (Greek xanthds = yellow, ph lon= leaf leaf yellow). This was later proven to be identical with L. (Latin luteus=yellow) isolated from egg yolk by Willstatter and Escher in 1912, the structure of the latter was elucidated in 1930 by Karrer. Today the name xanthophylls is used generally as a group name for oxygenated carotinoids (hydroxy compounds, epoxides, some 0x0 compounds). 

Sapogenina. Group name for the aglycones of the steroid saponins or triterpene saponins see also steroid sapogenins. 

Nomenclature. Vitamin E group name for derivatives of 6-chromanol. 

Nomenclature. Vitamin K (menadione, vitamin K3) group name for menadione and all of its derivatives with antihemorrhagic activity in vitamin K-deficient animals. 

Nomenclature. Niacin (vitamin PP) group name for nicotinic acid, nicotinamide, NAD, and NADP. 

Nomenclature. Pyridoxine (vitamin Bg) group name for pyridoxine (pyridoxol), pyridoxal, pyridoxamine and the 5 -phosphorylated derivatives of these compounds. 

Nomenclature. Folic acid, pteroylglutamic acid (PteGlu) folates also used as a group name for a family of more than 100 related compounds that have been modified on the pterin moiety, on N-5 and/or N-10, and on glutamyl side-chain. 

Common functional group names for ketones (in parentheses above) are obtained simply by separately naming the two groups attached to the carbonyl group and adding the word ketone as a separate word. 

Change the -yl ending of the other hydrocarbon group to -oxy to obtain the alkoxy group name. For example, CH3O— is called methoxy. 

Boilers Group name for nitrocellulose and lacquer solvents. 

Brockmann [ 1 ] has given group names for each hydroxylation pattern, individual members are then designated by greek letters in alph eticai order with increasing Rf value. However, the system has not always been adhered to if more than one name has been given to any one anthracyclinone, then the name consistent with Brockmann s scheme is quoted in the table. 

Illite. A group name for micaceous clay minerals of variable composition. The name derives from the fact that it was from Illinois (USA) clays and shales that samples were isolated by R. E. Grim, R. H. Bray, and W. F. Bradley Amer. Mineral, 22, (7), 813,1937) who first...
