Homo-gamma-linolenic acid (HGLA), also known as 6,9,12-octadecatrienoic acid, is a polyunsaturated fatty acid (PUFA) that belongs to the omega-6 family. It is an essential nutrient, meaning that our body cannot produce it on its own and must be obtained through diet or supplementation. HGLA is synthesized from gamma-linolenic acid (GLA), which is found in plant oils such as borage, evening primrose, and black currant seed oils. This nutrient plays a crucial role in various physiological processes, including the production of prostaglandins and the maintenance of healthy skin, hair, and nails. HGLA is also believed to have anti-inflammatory properties, which can be beneficial for managing conditions like rheumatoid arthritis and other inflammatory disorders. However, it is important to note that excessive consumption of omega-6 fatty acids, including HGLA, may lead to an imbalance with omega-3 fatty acids, potentially contributing to inflammation. Therefore, a balanced intake of both omega-3 and omega-6 fatty acids is recommended for optimal health.

Check Digit Verification of cas no

The CAS Registry Mumber 5598-38-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,9 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5598-38:
(6*5)+(5*5)+(4*9)+(3*8)+(2*3)+(1*8)=129
129 % 10 = 9
So 5598-38-9 is a valid CAS Registry Number.

Synthesis of phosphatidylcholine having a very long chain polyunsaturated fatty acid

Haider, Syed Shabbir,Tanaka, Masatoshi,Alam, Md Khorshed,Nakajima, Shuhei,Baba, Naomichi,Shimizu, Sakayu

, p. 175 - 176 (2007/10/03)

A phosphatidylcholine 9 bearing icosadienoyl and docosahexaenoyl groups at the 1-and 2-positions respectively was synthesized. The synthetic route involves carbon chain elongation of linoleic acid via malonic ester synthesis, preparation of lyso-phosphatidylcholine via lipase-catalyzed mono-acylation of 2-O-methoxyethoxymethylglycerol and phosphodiester synthesis, and finally DCC-mediated esterification.

SPECIFICITY OF THE ENZYME SYSTEM PRODUCING LONG CHAIN ALDEHYDES IN THE GREEN ALGA, ULVA PERTUSA

Kajiwara, Tadahiko,Yoshikawa, Hiroshi,Matsui, Kenji,Hatanaka, Akikazu,Kawai, Tetsuo

, p. 407 - 410 (2007/10/02)

The greater part of the enzyme activity producing long chain aldehydes (LCA) such as (8Z)-heptadecanal, (8Z,11Z)-heptadecadienal, (8Z,11Z,14Z)-heptadecatrienal was found in the 4000 g precipitate of homogenates of the green alga, Ulva pertusa.The LCA-forming activity was readily solubilized from the precipitate by addition of 0.2percent Triton X-100.The solubilized LCA-forming activity showed an optimum pH in the range 8.5-9.5. α-Linolenic acid was a very good substrate, but γ-linolenic acid was a poor substrate for the activity.Linoleic acid was the best substrate of an entire series of (ζ6Z, ζ9Z)-dienoic acids, in which the chain length varied from C13 to C20.Key Word Index - Ulva pertusa; green alga; odour; aldehydes; fatty acids; substrate specificity.
