Alpha Linolenic Acid and Linoleic Acid Metabolism

Bos taurus
Linoleic acid (LNA) is a polyunsaturated fatty acid (PUFA) precursor to the longer n−6 fatty acids commonly known as omega-6 fatty acids. Omega-6 fatty acids are characterized by a carbon-carbon double bond at the sixth carbon from the methyl group. Similarly, the PUFA alpha-linoleic acid (ALA) is the precursor to n-3 fatty acids known as omega-3 fatty acids which is characterized by a carbon-carbon double bond at the third carbon from the methyl group. Both LNA and ALA are essential dietary requirements for all mammals since they cannot be synthesized natively in the body. Both undergo a series of similar conversions to reach their final fatty acid form. LNA enters the cell and is catalyzed to gamma-linolenic acid (GLA) by acyl-CoA 6-desaturase (delta-6-desaturase/fatty acid desaturase 2). GLA is then converted to dihomo-gammalinolenic acid (DGLA) by elongation of very long chain fatty acids protein 5 (ELOVL5). DGLA is then converted to arachidonic acid (AA) by acyl-CoA (8-3)-desaturase (delta-5-desaturase/fatty acid desaturase 1). Arachidonic acid is then converted to a series of short lived metabolites called eicosanoids before finally reaching it's final fatty acid form.

alpha-Arbutin Drug Metabolism

Homo sapiens
alpha-Arbutin is a drug that is not metabolized by the human body as determined by current research and biotransformer analysis. alpha-Arbutin passes through the liver and is then excreted from the body mainly through the kidney.

alpha-Linolenic Acid Metabolism

Arabidopsis thaliana
alpha-Linolenic acid is a poly-unsaturated fatty acid with an 18-carbon chain and three cis double bonds. Its primary role in Arabidopsis thaliana is in being a precursor of the phytohormone jasmonic acid. Being a precursor for jasmonic acid, it plays a role in gene responses to feeding from insects. It is also a precursor to other molecules involved in defense signalling such as cis-3-hexenyl acetate. alpha-Linolenic acid itself modulates gene transcription in response to hyperosmotic salinity, heat acclimation, and oxidative stress. alpha-Linolenic acid is released from the hydrolysis of a phosphatidylcholine membrane lipid. It then has a hydroperoxy group added by a dioxygenase in either the 2, 9, or 13 position to form 2(R)-HPOT, 9(S)-HPOT, or 13(S)-HPOT respectively. The oxidation of alpha-linolenic acid to 13(S)-HPOT is the first step in the jasmonic acid synthesis and leads to that separate pathway. 2(R)-HPOT is formed in an oil body and undergoes a spontaneous decarboxylation to form a heptadecatrienal. 9(S)-HPOT, or 13(S)-HPOT are both formed in a chloroplast and cleaved by probable inactive linolenate hydroperoxide lyase to form an aldehyde and an oxo-carboxylic acid. The hexenal from 13(S)-HPOT is reduced by alcohol dehydrogenase class-P to form a hexenol, which undergoes an esterification with acetyl-CoA to form 3-hexenyl acetate.
