  2. Ketone halogenation - Wikipedia

    en.wikipedia.org/wiki/Ketone_halogenation

    On α,β-Unsaturated ketones or enones, it's possible to halogenate with iodine selectively on the more saturated alpha on the ketone selectively over the unsaturated side. Iodine is preferred due to it being more reactive than alkyl bromides which makes this reaction quite useful. [ 3 ]

  3. α-Halo ketone - Wikipedia

    en.wikipedia.org/wiki/Α-halo_ketone

    Halo ketones react with phosphites in the Perkow reaction. The halo group can be removed in reductive dehalogenation of halo ketones. α-Halo ketones can also be converted to alkenes by treatment with hydrazine. Due to the presence of two electron withdrawing groups (carbonyl and halide), the α-hydrogen is acidic.

  4. Urinalysis - Wikipedia

    en.wikipedia.org/wiki/Urinalysis

    Positive result on a Ketostix test strip, which is specialized for measuring ketones. Ketone bodies are products of fat breakdown. When the body relies on fats, rather than carbohydrates, as its main energy source, increased levels of ketones occur in the blood and urine. The presence of detectable levels of ketones in the urine is called ...

  5. Urine test strip - Wikipedia

    en.wikipedia.org/wiki/Urine_test_strip

    Automatic analysis of urine test strips using automated urine test strip analysers is a well-established practice in modern-day urinalysis. They can measure calcium , blood, glucose, bilirubin, urobilinogen, ketones, leukocytes, creatinine , microalbumin , pH, ascorbic acid and protein.

  6. Urinary cast - Wikipedia

    en.wikipedia.org/wiki/Urinary_cast

    The most common type of cast, hyaline casts are solidified Tamm–Horsfall mucoprotein secreted from the tubular epithelial cells of individual nephrons. Low urine flow, concentrated urine, or an acidic environment can contribute to the formation of hyaline casts, and as such, they may be seen in normal individuals in dehydration or vigorous exercise.

  7. Halogenation - Wikipedia

    en.wikipedia.org/wiki/Halogenation

    In chemistry, halogenation is a chemical reaction which introduces one or more halogens into a chemical compound. Halide-containing compounds are pervasive, making this type of transformation important, e.g. in the production of polymers, drugs. [1]

  8. Ketonuria - Wikipedia

    en.wikipedia.org/wiki/Ketonuria

    Normally, the urine should not contain a noticeable concentration of ketones to give a positive reading. As with tests for glucose, acetoacetate can be tested by a dipstick or by a lab. The results are reported as small, moderate, or large amounts of acetoacetate.

  9. Ketosis - Wikipedia

    en.wikipedia.org/wiki/Ketosis

    Ketosis is a metabolic state characterized by elevated levels of ketone bodies in the blood or urine. Physiological ketosis is a normal response to low glucose availability. . In physiological ketosis, ketones in the blood are elevated above baseline levels, but the body's acid–base homeostasis is maintain
