Generic terms

The term glycoglycerolipid is used to designate glycolipids containing 

The term glycosphingolipid designates lipids containing at least one monosaccharide residue and either a sphingoid or a ceramide. The gly-cosphingolipids can be subdivided as follows. 

Sialoglycosphingolipids (gangliosides, containing one or more sialic acid residues)

The generic term azulene was first applied to the blue oils obtained by distillation, oxidation, or acid-treatment of many essential oils. These blue colours are usually due to the presence of either guaiazulene or velivazulene. The parent hydrocarbon is synthesized by dehydrogenation of a cyclopentanocycloheptanol or the condensation of cyclopentadiene with glutacondialdehyde anil. 

FOD is very similar to diesel fuel. Both are designated in economic studies by the generic term, middle distillates . 

Chem(o)informatic5 is a generic term that encompasses the design, creation, organization, management, retrieval, analysis, dissemination, visualization, and use of chemical information."... 

Silica. SiHca (qv) comes in various forms including quartz [14808-60-7]. It has found wide use as an abrasive in the past, particularly as an inexpensive coated abrasive for woodworking. The term sandpaper is stiU used as a generic term for coated abrasives in many quarters although the use of sand in coated abrasives has been almost entirely elkninated because of the hazard of siHcosis to the user and its inferior grinding properties (especially for metals). 

Pectin. Pectin [9000-69-5] is a generic term for a group of polysaccharides, mainly partially methoxylated polygalacturonic acids, which are located in the cell walls of all plant tissues. The main commercial sources of pectin are citms peel and apple pomace, where it represents 20—40% and 10—20% of the dry weight respectively. The pectin is extracted, the extract purified, and the pectin precipitated (50) increased extraction times lead to the production of low methoxyl pectins. 

Monta.n Wax. An important product of the direct extractive treatment of lignitic coals is montan wax [8002-53-7]. The term montan wax or Bergwachs refers strictiy to the material obtained by solvent extraction of suitable German brown coals. The generic term for similar materials is montana wax. The small quantities made outside Germany are usually referred to as montan, prefixed by the country of origin (see Waxes). 

Solvents. Petroleum naphtha is a generic term appHed to refined, pardy refined, or unrefined petroleum products. Naphthas are prepared by any of several methods, including fractionation of distillates or even cmde petroleum, solvent extraction, hydrocracking of distillates, polymerization of unsaturated (olefinic) compounds, and alkylation processes. Naphtha can also be a combination of product streams from more than one of these processes. 

Unlike other natural resins, shellac [9000-59-3] is derived from the hardened secretion of the lac insect (species l ccifer (Tachardia) lacca Kerr (family Coccidae), also known as Kerns lacca (Kerr)). Shellac is a refined grade of the cmde lac secretion and is the most widely known lac product. Therefore, shellac has been accepted as the common generic term. Over 50% of the world s supply is produced in the Indian provinces of Bihar and Orissa, with the remainder originating in adjacent areas of southeast Asia such as Sri Lanka, China, Thailand, and Myanmar. 

Asphalt [8052-42-4] is defined by the American Society for Testing and Materials (ASTM) (1) as a dark brown to black cementitious material in which the predominating constituents are bitumens that occur in nature or are obtained in petroleum processing. Bitumen is a generic term defined by ASTM as a class of black or dark-colored (soHd, semisoHd, or viscous) cementitious substances, natural or manufactured, composed principally of high molecular weight hydrocarbons, of which asphalts, tars, pitches, and asphaltites are typical. 

During the isolation of inhibin from foUicular fluid, some chromatographic fractions stimulated FSH release from cultured anterior pituitary cells, suggesting the existence of FSH releasing proteins (FRPs). Two FRPs, given the generic term activins, were subsequentiy isolated (131,132). One is composed of two disulfide-finked P-A subunits (activin A) the other consists of similarly finked P-A and P-B subunits (activin AB). 

Note Powder is a generic term for subdivided solid material, comprising pellets, granules and dust. Pellets have a diameter greater than 2 mm (U.S. No. 10 Standard Sieve) and typically above 3 mm. Granules have a diameter between 0.42 and 2 mm, although granular powders typically contain dust. Dusts have a diameter less than 0.42 mm and as low as I pm. Suspensions of particles smaller than I pm are known as fumes. 

TIricooRlinate caibocations are fiequendy called carbonium ions. The terms methyl cation, butyl cation, etc., are used to describe the c >rTesixiiulir.ji tricoordinate cations. Chemical Abstracts uses as specific names methylium, ethyUum, propylium. We will use carbocation as a generic term for trivalent carbon cations. 

Chemical Designations - Synonyms Sodium phosphate is generic term and includes the following (1) monosodium phosphate (MSP sodium phospWe, monobasic), (2) disodium phosphate (DSP sodium phosphate dibasic), (3) trisodium phosphate (TSP sodium phosphate, tribasic), (4) sodium acid pyrophosphate (ASPP SAPP disodium pyrophosphate (TSPP), (6) sodium metaphosphate (insoluble sodium metaphosphate), (7) sodium trimetaphosphate, and (9) sodium tripolyphosphate (STPP TPP) Chemical Formula (1) NaHjPO (2) Na HPO (3) NajPO (4) Na H P O, (5) Na P O, (6) (NaPOj) (7) (NaP03)3 (8) (NaP03) NaO (9) Na,P30,o. 

Pressure Relief Valve - This is a generic term applying to relief valves, safety valves or safety relief valves. It is commonly abbreviated to "PR Valve". 

This book makes reference to flame arresters, deflagration flame arresters, and detonation flame arresters. Flame arresters is the generic term for both deflagration and detonation flame arresters. Deflagration flame arresters are nsed when a flame only propagates at snbsonic velocity, whereas detonation arresters are nsed when a flame can propagate at all velocities inclnding snpersonic velocities.
