biyoyararlılık

Turkish - English

Definition of biyoyararlılık in Turkish English dictionary

bioavailability

The availability of a nutrient for microbially-mediated degradation or transformation Typically, for a nutrient to be bioavailable, it must (1) be within physical proximity to the cell and (2) be dissolved in the aqueous phase, to be transported across the cell membrane Thus, nutrients that are adsorbed to surfaces or sequestered into micropores that physically exclude cells are generally considered unavailable Bioavailability should not be confused with recalcitrance, although distinguishing the two in the environment can be very difficult

The rate and extent to which a drug is absorbed or is otherwise available to the treatment site in the body

The extent to which a dose of drug reaches its site of action

Rate and extent to which a drug is absorbed or is otherwise available to the treatment site in the body

The amount of drug which reaches the site of physiological activity after administration

{i} extent and rate which a drug (or other substance) is absorbed and becomes available in a physiologically active form

The degree to which toxic substances or other pollutants are present in sediments or elsewhere in the ecosystem to affect or be taken up by organisms Some pollutants might be "bound up" or unavailable because they are attached to clay particles or are buried by sediment The amount of oxygen, pH, temperature, and other conditions in the water can affect availability

Nutritional bioavailability encompasses availablity, absorption, retention and utilization of nutrients Absorption in vivo is a key factor for the nutrient to have the suggested biological significance

The capacity of a chemical constituent to be taken up by living organisms either through physical contact or ingestion

A measure of a nutrient s utilization by the body in a biologically meaningful way

A general term to describe the accessibility of contaminants to ecological populations Bioavailability consists of: 1) a physical aspect related to phase distribution and mass transfer, and 2) a physiological aspect related to the suitability of the contaminant as a substrate

the degree a drug or nutrient is available to the body Bioavailability is influenced by how much the substance is absorbed and circulated

The rate and extent to which a substance is absorbed and circulated within the body

The extent to which a metabolite or drug can be utilized by its site of action Some forms of calcium have higher bioavailability than others

the extent to which a substance (e g , a drug) is absorbed and circulated in the body

The availability of chemicals to potentially biodegradative microorganisms

The degree to which a material in environmental media can be assimilated by an organism (EPA 1997)

The simplicity in which nutrients can be absorbed

a general term that refers to how well a nutrient can be absorbed and used by the body

The relative ability of nutrients in foods to be properly digested, and absorbed For example, the iron in vegetable foods is less absorbable than the iron in meat foods The bioavailability of iron in vegetables increases when vitamin C is also present, having been consumed during the same meal
