International audience; In their native state, milk lipids are present in the form of dispersed droplets called Milk Fat Globules (MFG, diameter 0.1-20 μm, average = 4 μm in bovine milk) [1,2]. The native MFG is constituted by a triglyceride core c

Lipids of human milk or infant formula convey most of the energy necessary to support the newborn growth. Until recently, infant formula chemical composition had been optimized but not their structure. And yet, more and more proofs of evidence have s

Publikováno v: Biomolecules, Vol 12, Iss 8, p 1047 (2022)

The chloroplast protein CP12, which is widespread in photosynthetic organisms, belongs to the intrinsically disordered proteins family. This small protein (80 amino acid residues long) presents a bias in its composition; it is enriched in charged ami

Publikováno v: Journal of Lipid Research, Vol 56, Iss 5, Pp 1057-1067 (2015)

A continuous assay is proposed for the screening of acidic, neutral, or alkaline lipases using microtiter plates, emulsified short- and medium-chain TGs, and a pH indicator. The lipase activity measurement is based on the decrease of the pH indicator

Storage Compound Accumulation in Diatoms as Response to Elevated CO2 Concentration

Autor: Erik L. Jensen, Karen Yangüez, Frédéric Carrière, Brigitte Gontero

Publikováno v: Biology, Vol 9, Iss 1, p 5 (2019)

Accumulation of reserve compounds (i.e., lipids and chrysolaminarin) in diatoms depends on the environmental conditions, and is often triggered by stress conditions, such as nutrient limitation. Manipulation of CO2 supply can also be used to improve
