Skin, blood pressure, rheumatoid arthritis and gamma-linolenic acid

Healthy skin and gamma-linolenic acid gamma-Linolenic acid (GLA), an omega-6 essential fatty acid, like its precursor linoleic acid (the most abundant polyunsaturated fatty acid in human skin epidermis, where it’s involved in the maintenance of the epidermal water barrier), plays important roles in the physiology and pathophysiology of the skin. Studies conducted on humans revealed that gamma-linolenic acid: improves skin moisture, firmness, […]

Long chain fatty acid synthesis

Contents in brief: Fatty acid synthesis De novo fatty acid synthesis in plants and animals Synthesis of long chain saturated and unsaturated fatty acids Omega-3 and omega-6 PUFA synthesis References Fatty acid synthesis When excess calories are consumed from carbohydrates or proteins, such surplus is used to synthesize fatty acids and then triacylglycerols, while it doesn’t occur if […]

Omega-6 polyunsaturated fatty acids

The synthesis of omega-6 polyunsaturated fatty acids Omega-6 polyunsaturated fatty acids are the major polyunsaturated fatty acids (PUFA) in the Western diet (about 90% of all of them in the diet), being components of most animal and vegetable fats. Omega-6 polyunsaturated fatty acids and linoleic acid Within the omega-6 (ω-6) family, linoleic acid is one of the […]

Omega-3 polyunsaturated fatty acids

The synthesis of omega-3 polyunsaturated fatty acids Within omega-3 (ω-3) polyunsaturated fatty acid family: alpha-linolenic acid; eicosapentaenoic acid or EPA; docosahexaenoic acid or DHA. are important fatty acids. Omega-3 polyunsaturated fatty acids and α-linolenic acid Like linoleic acid (omega-6 fatty acid), alpha-linolenic acid or ALA is a primary product of plant polyunsaturated fatty acid or PUFA synthesis and […]
