Villus lacteals ( lymph capillary ) collect absorbed chylomicrons, which are lipoproteins composed of triglycerides, cholesterol and amphipathic proteins, and are taken to the rest of the body through the lymph fluid.
42.
The C-terminal end of the channel extends into a loop ( residues 47 50 ) that connects the trans membrane domain to the C-terminal amphipathic helix . ( 46 62 ).
43.
The phospholipds are amphipathic, consisting of a hydrophobic tail which faces inwards, binding with the triglycerides and cholesterol, and a hydrophilic head which faces outwards, making the lipoproteins water-soluble.
44.
This likely interacts with the cationic face of lacritin's C-terminal amphipathic alpha helix . ( 3 ) An N-terminal chondroitin sulfate chain that also likely binds to the cationic face.
45.
The TAZ1 domain in P300 and the TAZ2 ( CH3 ) domain in CBP have each been shown to have four amphipathic helices, organised by three zinc-binding clusters with HCCC-type coordination.
46.
Investigations in organic matter interactions with clay minerals led to the development of the idea of dual mode bonding in which amphipathic molecules interact with substrates by both hydrophobic-hydrophobic and hydrophilic-hydrophilic interactions.
47.
While the actual foam activity of beer depends on the presence of carbon dioxide, it is the surface-active materials like amphipathic polypeptides from malt that determine size, shape and length of the foam.
48.
The GDP / GTP structural cycles of human Arf1 and Arf6 feature a unique conformational change that affects the beta2beta3 strands connecting switch 1 and switch 2 ( interswitch ) and also the amphipathic helical N-terminus.
49.
Antibodies directed to the C-, but not N-, terminus of human lacritin are most effective-in keeping with the predicted conservation of the C-terminal amphipathic alpha helix necessary for cell targeting.
50.
More specifically, they are amphipathic glycosides grouped phenomenologically by the soap-like foaming they produce when shaken in aqueous solutions, and structurally by having one or more hydrophilic glycoside moieties combined with a lipophilic triterpene derivative.
