The free fatty acid receptor 1 (FFA1 or GPR40) is established as an interesting potential target for treatment of type 2 diabetes. However, to obtain optimal ligands, it may be necessary to limit both lipophilicity and polar surface area, translating to a need for small compounds. We here describe the identification of 24, a potent FFA1 agonist with low lipophilicity and very high ligand efficiency that exhibit robust glucose lowering effect.

A key factor influencing consumer acceptance of soybean products is the aroma and taste profile, which can be modulated through fermentation using unique microbial strains. This study aimed to identify and characterize novel microbial strains with the potential to enhance flavour profiles including umami, while reducing undesirable flavour notes such as beany aromas. The results showed an 800% (8-fold) increase in free amino acids in samples fermented with , which correlated with an increase in umami intensity as measured using an E-tongue.

Introduction: Atopic dermatitis (AD) is an allergic disease caused by various factors that can affect an individual's appearance and cause psychological stress. Therefore, it is necessary to investigate the underlying mechanisms and develop effective treatment strategies. The gut microbiota and bacterial metabolism play crucial roles in human diseases.

Research on enhancing the production of lipids, particularly polyunsaturated fatty acids that are considered important for health, has focused on improvement of metabolism as well as heterologous expression of biosynthetic genes in the oleaginous fungus . To date, the productivity and production yield of free fatty acids have been enhanced by 10-fold to 90-fold via improvements in metabolism and optimization of culture conditions. Moreover, the productivity of ester-type fatty acids present in triacylglycerols could be enhanced via metabolic improvement.

Background: Monoacylglycerol lipase (MAGL) belongs to the serine hydrolase family; it catalyzes MAG to produce glycerol and free fatty acids (FFAs), which is the final step in triacylglycerol (TAG) hydrolysis. The effects of MAGL on comprehensive lipid metabolism and plant growth and development have not been elucidated, especially in Arachis hypogaea, an important oil crop.
Results: Herein, AhMAGL3b encoding a protein with both hydrolase and acyltransferase regions, a member of MAGL gene family, was cloned and overexpressed in Arabidopsis thaliana.

The bioavailability of long-chain omega-3 fatty acids is a critical yet often overlooked factor influencing their efficacy. This review evaluates the bioavailability of EPA/DHA from acute (single-dose) and chronic human studies, focusing on (a) chemical forms such as triacylglycerols (TAG, natural and re-esterified, rTAG), free fatty acids (FFA), and phospholipids (PL) from sources like fish, krill, and microalgae, and (b) delivery methods like microencapsulation and emulsification. Bioavailability for isolated chemically forms followed the order: FFA > PL > rTAG > unmodified TAG > ethyl esters (EE).
