Animal oleic acid Suppliers

Animal oleic acid is light yellow transparant liquid.The acid value is (mg/g)190-202,the iodine value(Ig/100g) 80-100  and  the saponification value (mg/g)195-205.It mustn't be mixed with acid-base ant from heat and fire. In animal cells, oleic (18:1, n-9) acid is created by the dehydrogenation of stearic acid. Oleic acid is further elongated and desaturated into a family of n-9 fatty acids. Historically, oleic acid and its precursors have been provided to cells in culture as components of serum, albumin or esterified to molecules such as cholesterol. Oleic acid is poorly soluble in aqueous media and susceptible to peroxidation. The advent of serum-free, animal-protein-free and protein-free media formulations has increased the difficulty of delivering oleic acid to cells in culture.
CAS: 112-80-1; Molecular weight: about  282 g/mol.
Natural fatty acids have their double bonds in the cis-configuration and are usually esterified to glycerol backbones to form complex lipids. Fatty acids that contain more than one double bond are called polyunsaturated fatty acids (PUFAs). It is mainly used in rubber, plastic, printing, coating, washing, leather, metallurgy, chemical, etc.
It is also used in the industries including textile, chemical, medicine, leather-making, stationary, rolling lubricant, re dressing and paper making etc..
Oleic acid is a monounsaturated fatty acid found naturally in many plant sources and in animal products. It is an omega-nine fatty acid, and considered one of the healthier sources of fat in the diet. The proper formulation of oleic acid as a stable supplement is a challenge for the development of proprietary media useful for biomanufacturing and tissue engineering.
