  2. Amino acid score - Wikipedia

    en.wikipedia.org/wiki/Amino_acid_score

    Amino acids are important in food because it aids in the body’s ability to efficiently digest food. An amino acid is a necessary chemical that is found organically in foods. Amino acids are composed of a side chain , a basic amino group, and a carboxyl group. Based on an aminos R group every amino acid will react different because of shape or ...

  3. Acceptable daily intake - Wikipedia

    en.wikipedia.org/wiki/Acceptable_Daily_Intake

    Acceptable daily intake or ADI is a measure of the amount of a specific substance (originally applied for a food additive, later also for a residue of a veterinary drug or pesticide) in food or drinking water that can be ingested (orally) daily over a lifetime without an appreciable health risk. [1]

  4. Dose (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Dose_(biochemistry)

    Drugs come with a recommended dose in milligrams or micrograms per kilogram of body weight, and that is used in conjunction with the patient's age and body weight to determine a safe dose. In single-dose scenarios, the patient's body weight and the drug's recommended dose per kilogram are used to determine a safe one-time dose.

  5. Parts-per notation - Wikipedia

    en.wikipedia.org/wiki/Parts-per_notation

    Parts-per notation is often used describing dilute solutions in chemistry, for instance, the relative abundance of dissolved minerals or pollutants in water.The quantity "1 ppm" can be used for a mass fraction if a water-borne pollutant is present at one-millionth of a gram per gram of sample solution.

  6. Threshold limit value - Wikipedia

    en.wikipedia.org/wiki/Threshold_limit_value

    The TLV is an estimate based on the known toxicity in humans or animals of a given chemical substance, and the reliability and accuracy of the latest sampling and analytical methods. TLVs do not take into account financial or technical feasibility for application in the workplace, instead solely focusing on health based recommendations to ...

    Dosage typically includes information on the number of doses, intervals between administrations, and the overall treatment period. [3] For example, a dosage might be described as "200 mg twice daily for two weeks," where 200 mg represents the individual dose, twice daily indicates the frequency, and two weeks specifies the duration of treatment.

  8. Biological activity - Wikipedia

    en.wikipedia.org/wiki/Biological_activity

    However, chemical compounds may show some adverse and toxic effects which may prevent their use in medical practice. Biological activity is usually measured by a bioassay and the activity is generally dosage-dependent, which is investigated via dose-response curves. Further, it is common to have effects ranging from beneficial to adverse for ...

  9. Trace element - Wikipedia

    en.wikipedia.org/wiki/Trace_element

    A trace element is a chemical element of a minute quantity, a trace amount, especially used in referring to a micronutrient, [1] [2] but is also used to refer to minor elements in the composition of a rock, or other chemical substance. In nutrition, trace elements are classified into two groups: essential trace elements, and non-essential trace ...
