Pro-Hyp (PO) accounts for many beneficial biological effects of collagen hydrolysates for skin and bone health. The objective of this study was to conjugate PO with glucosamine (GlcN) to create a novel glycopeptide Pro-Hyp-CONH-GlcN (POGlcN) and then to investigate the potential involvement of multiple transepithelial transport pathways for this(More)
Collagen was extracted from raw bovine hide and hydrolyzed by one of three enzymes - Alcalase, Flavourzyme, or trypsin - or by using a combination of two or three of these enzymes. The Alcalase-containing enzymatic hydrolysis treatments generated a greater proportion of hydrolysates with molecular weight (MW) <2kDa (79.8-82.7%). Flavourzyme-containing(More)
Tobacco samples of a same cultivar grown in different plantations in China were evaluated for their chemical compositions at different maturities for the first time. This was accomplished by a comprehensive and reliable method using gas chromatography-mass spectrometry (GC-MS) and high performance liquid chromatography-photodiode array-quadrupole(More)
