Acetyl-CoA carboxylase (ACCase) catalyzes the first committed step of fatty acid synthesis, the carboxylation of acetyl-CoA to malonyl-CoA. Two physically distinct types of enzymes are found in nature. Heteromeric ACCase composed of four subunits is usually found in prokaryotes, and homomeric ACCase composed of a single large polypeptide is found in eukaryotes. Most plants have both forms, the heteromeric form in plastids, in which de novo fatty acids are synthesized, and the homomeric form in cytosol. This review focuses on the structure and regulation of plant heteromeric ACCase and its manipulation for plant breeding.

Olanzapine (OLZ) is widely used in the treatment of schizophrenia, and its metabolic side effects have garnered significant attention in recent years. Despite this, the specific side effects of OLZ and the underlying mechanisms remain inadequately understood. To address this gap, zebrafish (Danio rerio) were exposed to OLZ at concentrations of 35.

Ferroptosis is a newly identified programmed cell death induced by iron-driven lipid peroxidation and implicated as a potential approach for tumor treatment. However, emerging evidence indicates that hepatocellular carcinoma (HCC) cells are generally resistant to ferroptosis and the underlying molecular mechanism is poorly understood. Here, our study confirms that S100 calcium binding protein P (S100P), which is significantly up-regulated in ferroptosis-resistant HCC cells, efficiently inhibits ferroptosis.

A comprehensive phytochemical investigation of the twigs/leaves and flower buds of , a rare deciduous shrub native to China, led to the isolation of 39 structurally diverse compounds. These compounds include 11 iridoid glycosides (- and -), 20 triterpenoids (, , and -), and 8 phenylpropanoids (-). Among these, amabiliosides A () and B () represent previously undescribed bis-iridoid glycosides, while amabiliosides C () and D () feature a unique bis-iridoid-monoterpenoid indole alkaloid scaffold with a tetrahydro--carboline-5-carboxylic acid moiety.

Consuming food containing ingredients with a documented impact on lipid metabolism can help fight overweight and obesity. The simplest way to reduce the level of fatty acids is to block their synthesis or increase the rate of their degradation. This study aimed to determine the effect of resveratrol, , conjugated linoleic acid (CLA), , CLA, and various variants of their combinations on de novo fatty acid biosynthesis in 3T3-L1 adipocytes.

Numerous compounds involved in the regulation of the cardiovascular system are also engaged in the control of metabolism. This review gives a survey of literature showing that arginine vasopressin (AVP), which is an effective cardiovascular peptide, exerts several direct and indirect metabolic effects and may play the role of the link adjusting blood supply to metabolism of tissues. Secretion of AVP and activation of AVP receptors are regulated by changes in blood pressure and body fluid osmolality, hypoxia, hyperglycemia, oxidative stress, inflammation, and several metabolic hormones; moreover, AVP turnover is regulated by insulin.
