Mighri, Characterization of Complex Mixture of Phytosphingosine
type Ceramides from the Tunisian Reaumuria vermiculata.
Twenty potential biomarkers, including L-acetylcarnitine (1), propionylcarnitine (2), unknown (3), phytosphingosine
(4), glycoursodeoxycholic acid (5), LPC(14:0) (6), sphinganine (7), LPC(20:5) (8), LPC(16:1) (9), LPC(18:2) (10), LPC(18:3) (11), LPC(22:5) (12), LPC(16:0) (13), LPC(18:1) (14), LPC(22:4) (15), LPC(17:0) (16), LPC(20:2) (17), elaidic carnitine (18), LPC(18:0) (19) and LPC(20:1) (20), were identified by their accurate mass and MSE spectra.
lc), of which the long chain base and fatty acids were C-18 phytosphingosine
and 2-hydroxy fatty acids, respectively.
Developed with CeraVe's trademark ceramide, hyaluronic acid and phytosphingosine
formula, the lotion includes niacinamide, which has been clinically proven to help the skin produce more ceramides and fatty acids, which are essential for barrier repair.
The raft fractions were separated in OptiPrep centrifugal gradients and both the ergosterol concentrations and fatty acid profiles (as FAMEs) determined by GC following extraction and hydrolysis of phosphoglyceride ester, sterol ester, and phytosphingosine
This contains a special botanical complex and phytosphingosine
that promises to eliminate dark circles under eyes in six to 12 weeks.
Consideration of biogenesis and steric hinderance of sphingolipids, generally were acknowledged to determine the absolute stereochemistry of the phytosphingosine
The results showed that eight metabolites (KA, xanthurenic acid, phenylacetylglycine, N2-succinyl-L-ornithine, leucylproline, L-phenylalanyl-L-hydroxyproline, C18 phytosphingosine
, cholic acid) were interpreted as potential biomarkers and amino acid metabolism, gut microflora, bile biosynthesis were associated with GF-induced hepatotoxicity (Geng et al.
The "actives" presentation highlighted two recent introductions now available for skin-active formulations in the US--Tego Cistus, a standardized extract from the plant Cistus incanus to protect skin from environmental stresses, and Phytosphingosine
SLC, a novel sphingolipid derivative that helps to reduce the appearance of chronological aging and photo-aged skin.
exerted strong cytotoxic effects, modulated the Caenorhabditis elegans muscarinic acetylcholine receptor-mediated signal transduction pathway and induced cell death (Lee et al.
This yeast produces high amounts of the ceramide precursor phytosphingosine
, which is secreted into the growth medium, extracted and further converted into a range of ceramides marketed as valuable cosmetic ingredients.
