GENERAL
DESCRIPTION & APPLICATIONS
|
Lactic acid (chemically, alpha or 2-Hydroxypropionic acid) takes roles in metabolic processes in the body; in red blood and in
skeletal muscle tissues as a product of glucose and glycogen metabolism. Lactic acid is an "alpha
hydroxy acid: which has a hydroxyl group on the
carbon atom next to the acid group. If the hydroxy group is on the second carbon
next to the acid group, it is called beta-hydroxy acid. Lactic acid is converted
in vivo to pyruvic acid (an alpha keto acid) which occurs as an intermediate
product in carbohydrate and protein metabolism in the body. Lactic
acid occurs as two optical isomers since the central carbon atom is bound to
four different groups; a dextro and a levo form ( or an inactive racemic mixture
of the two); only the levo form takes part in animal metabolism. Lactic acid is
present in sour milk and dairy products such as cheese, yogurt, and koumiss,
leban, wines. Lactic acid causes tooth decay since lactic acid bacteria
operates in the mouth. Although it can be prepared by chemical synthesis,
production of lactic acid by fermentation of glucose and other sugar substances
in the presence of alkaline such as lime or calcium carbonate is a less
expensive method. The six-carbon glucose molecule is broken down to two
molecules of the three-carbon compounds (lactic acid), during this anaerobic
condition. Synthetic lactic acid is used commercially in tanning leather and
dyeing wool; as a flavouring agent and preservative in food processing and
carbonated beverages; and as a raw material in making plastics, solvents, inks,
and lacquers; as a catalyst in numerous chemical processes. Lactic Acid is
available as aqueous solutions of various concentrations, usually 22 - 85
percent (pure lactic acid is a colourless, crystalline substance.) Some examples
of lactates (salts or esters of lactic acid) are:
- Ammonium
Lactate (NH4C3H5O3, CAS RN: 515-98-0): clear to yellow, syrupy liquid used in in
electroplating, in finishing leather and as humectant for food, pharmaceutical,
and cosmetics.
- Butyl Lactate (CH3CHOHCOOC4H9, CAS RN:138-22-7): a clear
liquid: nontoxic, miscible with many solvents; used as a solvent for varnish,
lacquers, resins and gums, used in making paints, inks, dry cleaning fluid,
flavoring and as a chemical intermediate.
- Calcium Lactate Pentahydrate
[Ca(C3H5O3)2·5H2O, CAS RN: 814-80-2] : white crystals; soluble in water; used as
a calcium source; administered orally in the treatment of calcium deficiency; as
a blood coagulant.
- Ethyl Lactate (CH3CHOHCOOC2H5,
CAS RN: 97-64-3):
clear liquid with mild odur; boiling point 154 C; miscible with alcohols,
ketones, esters, and hydrocarbons as well as with water; used in pharmaceutical
preparations, feed additive, as a flavoring ( odor description: sweet butter,
coconut, fruity, creamy dairy, butterscotch) and as a solvent for cellulose
compounds such as nitrocellulose, cellulose acetate, and cellulose
ethers.
- Magnesium Lactate Trihydrate [Mg(C3H5O3)2·3H2O, CAS RN: 18917-93-6
]: white crystals with bitter taste; soluble in water, slightly soluble in
alcohol; used in medicine and as an electrolyte replenisher.
- Manganese
Lactate Trihydrate [Mn(C3H5O3)2·3H2O]: pale red crystals; insoluble in water and alcohol;
used in medicine.
- Mercuric Lactate [Hg(C3H5O3)2]: poisonous white
powder that decomposes when heated; soluble in water; used in
medicine.
- Methyl Lactate (CH3CHCHCOOCH3): clear liquid with mild odur;
boiling point 145 C; miscible with alcohols, ketones, esters, and hydrocarbons
as well as with water; used in pharmaceutical preparations, feed additive, as a
flavoring and as a solvent for cellulose compounds such as nitrocellulose,
cellulose acetate, and cellulose ethers.
- Sodium Lactate (CH3CHOHCOONa,
CAS RN: 72-17-3) clear to yellow, hygroscopic syrupy liquid; soluble in water;
melting point 17 C; used in medicine, in antifreeze, and hygroscopic agent and
as a corrosion inhibitor.
- Zinc Lactate (Zn(C3H5O3)2·2H2O, CAS RN:
16039-53-5): white crystals; used as an additive in toothpaste and food;
preparation of drugs.

GENERAL
DESCRIPTION OF ZINC MINERAL |
Zinc is an essential mineral having a role in the maintenance of the body's
nervous and immune systems (T-cell function). This mineral is involved in the biochemical
reactions as an antioxidant in the healing process and develops normal tissues
Zinc is a cofactor in enzymatic reactions such as protein synthesis polymerases
and in carbonic acid anhydrase. Zinc maintains the body's alkaline balance. Zinc
finger, a structural domain found in many gene-regulatory proteins, is a
component of hydrophobic hormones acting stabilizing the biomembrane structures
and cell membrane metabolism. Zinc deficiencies may result in prolonged wound
healing, delayed sexual maturation, mental lethargy, skin changes, and
susceptibility to infections. Gluconate and citrate forms are mainly used as
zinc supplements. They are easily absorbed by the body. |
