Glossary
biotransformation: metabolism of contaminants transforming them into
different compounds.
Chromarod: quartz rod coated with a thin layer of silica sintered with soft glass.
cyclopropanoid fatty acids: fatty acids that have a ring structure of three carbon
atoms, usually near the middle of a fatty acid chain, where the ethylenic bonds
are normally found. They are frequently found in bacterial membrane phospholipids, but if found in depot fats of aquatic organisms, they have no known
function.
derivatization: preparation of a substance from another substance in such a
manner that the general structure of the parent substance is retained.
dietary deficiency: condition in animals resulting from the absence or inadequate
amount of a required dietary compound such as essential amino acids, essential
fatty acids, vitamins, and several metals.
endogenous lipid: lipid produced by the organism's own metabolism, as opposed
to that incorporated from the diet.
energy allocation strategy: biochemical processes by which organisms partition or allocate available (assimilated) energy into the main functions of somatic (protein) growth, basic maintenance, reproductive effort, and energy
(lipid) storage. The proportion of energy allocated to each process is dependent
on environmental food availability, temporal processes, and physiological
condition.
ether lipids: glycerol molecules with a hydrocarbon chain linked by an ether
(single oxygen) bond in one outside position. The other two positions may both
be occupied by esterified fatty acids (diacylglycerol ethers), or the other outside
position may contain a phosphoric acid-amino acid group as in ordinary phospholipids. They may then be called alkylacylphospholipids. (Note: the structure
of ether lipids is given in Ackman, this volume, Fig. 11.6.)
fasting endurance: ability of an animal to survive and remain active during a
short time period when the level of food resources, or its ingestion and assimilation, is insufficient to support the metabolic and growth needs of the animal.
foam: emulsion-like two-phase system in which the dispersal phase is a gas or air.
fugacity: escaping tendency of a contaminant from a compartment.
fugacity capacity: capacity of a compartment to hold a particular contaminant.
gametogenesis: production of gametes (i.e., eggs and sperm).
