Feem ntau, cov roj ntsha muaj roj muaj cov saw ncaj ntawm txawm tus naj npawb ntawm cov pa roj carbon atoms, nrog hydrogen atoms raws qhov ntev ntawm cov saw thiab ntawm ib kawg ntawm cov saw thiab ib pawg carboxyl (-COOH) ntawm lwm qhov kawg. … Nws yog pawg carboxyl uas ua rau nws muaj kua qaub (carboxylic acid).

Puas yog fatty acids?

Hauv chemistry, tshwj xeeb hauv biochemistry, fatty acid yog ib qho carboxylic acid nrog ntev aliphatic saw, uas yog saturated los yog unsaturated. Cov fatty acids uas tshwm sim feem ntau muaj cov saw hlau tsis sib xws ntawm tus lej ntawm cov pa roj carbon atoms, txij li 4 txog 28.

Vim li cas fatty acids siv?

Fatty acids yog lub tsev tsim cov roj hauv peb lub cev thiab hauv cov zaub mov uas peb noj. … Fatty acids muaj ntau lub luag haujlwm tseem ceeb hauv lub cev, suav nrog zog cia. Yog tias cov piam thaj (ib hom suab thaj) tsis muaj rau lub zog, lub cev siv cov roj fatty acids los txhawb lub hlwb.

fatty acids yog dab tsi?

Fatty acids: Molecules uas ntev chains ntawm lipid-carboxylic acid pom hauv cov rog thiab roj thiab hauv cov cell membranes ua ib feem ntawm phospholipids thiab glycolipids. (Carboxylic acid yog cov organic acid uas muaj cov pab pawg ua haujlwm -COOH.) Fatty acids los ntawm tsiaj thiab zaub rog thiab roj.

Dab tsi yog fatty acids thiab lawv siv?

Fatty acids pab ua lub zog rau cov leeg, lub plawv, thiab lwm yam kabmob ua lub tsev thaiv rau cov cell membranes thiab raws lilub zog cia rau lub cev. Fatty acids uas tsis siv los ua lub zog tau hloov mus ua triglycerides.
