  2. Hydrochloric acid - Wikipedia

    en.wikipedia.org/wiki/Hydrochloric_acid

    Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans.

  3. Insulin - Wikipedia

    en.wikipedia.org/wiki/Insulin

    Frederick Sanger sequenced the amino acid structure in 1951, which made insulin the first protein to be fully sequenced. [18] The crystal structure of insulin in the solid state was determined by Dorothy Hodgkin in 1969. Insulin is also the first protein to be chemically synthesised and produced by DNA recombinant technology. [19]

    Ingestion of ammonium chloride, hydrochloric acid, or other acidifying salts; The treatment and recovery phases of diabetic ketoacidosis; Volume resuscitation with 0.9% normal saline provides a chloride load, so that infusing more than 3–4L can cause acidosis; Hyperalimentation (i.e., total parenteral nutrition)

  5. Work-up - Wikipedia

    en.wikipedia.org/wiki/Work-up

    White solids of impure benzoic acid are obtained. The benzoic acid is decanted to remove the aqueous solution of impurities, more water is added, and the mixture is brought to a boil with more water added to give a homogeneous solution. The solution is allowed to cool slowly to room temperature, then in an ice bath to recrystallize benzoic acid.

    Frederick Sanger OM CH CBE FRS FAA (/ ˈ s æ ŋ ər /; 13 August 1918 – 19 November 2013) was a British biochemist who received the Nobel Prize in Chemistry twice.. He won the 1958 Chemistry Prize for determining the amino acid sequence of insulin and numerous other proteins, demonstrating in the process that each had a unique, definite structure; this was a foundational discovery for the ...

    Molisch test (using α-napthol) indicating a positive result (see purple ring). Molisch's test is a sensitive chemical test, named after Austrian botanist Hans Molisch, for the presence of carbohydrates, based on the dehydration of the carbohydrate by sulfuric acid or hydrochloric acid to produce an aldehyde, which condenses with two molecules of a phenol (usually α-naphthol, though other ...

    However, since blood is buffered with carbonate at physiological pH (near 7.4), free-base amines will be rapidly converted back into their acid form. In fact, 94.19% of cocaine will exist as the acid form under equilibrium at pH=7.4, calculated using the Henderson–Hasselbalch equation assuming a pKa of 8.61. [1]
