Sprecher, HowardBaykousheva, SvetlaThe authors hypothesized that a role for peroxisomes might be to chain shorten fatty acids but that the products would be transported to the endoplasmic reticulum where they would be esterified into lipids. Results showed that when microsomes and 1-acyl-sn-glycero-3-phosphocholine are added to peroxisomes that competing reactions take place, i.e. β-oxidn. and esterification.en-USβ-oxidationunsaturated fatty acidfatty acid oxidationperoxisomelipidbiosynthesisBaykouchevabeta-oxidationArticle
