Proteins, which are composed of amino acids, help transport lipids in the bloodstream. These proteins need to be able to cluster with other nonpolar molecules and exclude water. Which of the following would best describe the side chains of these amino acids in the lipid transport proteins? A ...

Proteins, which are composed of amino acids, help transport lipids in the bloodstream. These proteins need to be able to cluster with other nonpolar molecules and exclude water. Which of the following would best describe the side chains of these amino acids in the lipid transport proteins? A....
Hydrolyzed proteins Casein hydrolysate Whey protein hydrolysate Casein hydrolysate is made up of peptides from broken-down proteins. These peptides are short chains of amino acids, the building blocks of proteins. These smaller peptides may be easier to digest and less allergenic than...
Glycoproteins are proteins which contain oligosaccharide chains (glycans) covalently attached to amino acid side-chains. Glycoproteins often contain N-linked oligosaccharides with a glycosidic bond to nitrogen, typically on the amide side-chain of ___ . A. Ala B. Arg C. Asn D. Gly ...
Less is known about the physiological role of a wide variety of reactions that stably modify proteins by methylation at the amino terminus and at the side-chains of lysine and arginine residues. These latter modifications often are found on structural proteins, and one role of these methylation ...
DNA–protein crosslinks (DPCs) induced by aldehydes interfere with replication and transcription. Hereditary deficiencies in DPC repair and aldehyde clearance processes cause progeria, including Ruijs–Aalfs syndrome (RJALS) and AMeD syndrome (AMeDS) in
It is a multimeric protein composed of seven identical α-chains and a single copy of a unique β-chain. The latter was identified only recently and its structure determined by cDNA cloning. Both subunits in C4b-binding protein belong to the same superfamily of proteins composed predominantly of...
Although the difference between Val/Ile and Leu is not as radical, we predicted that the physical difference between the side chains of Val/Ile versus Leu (the second terminal methyl group on the amino acid chain) may also have a functional effect by making new contacts in the tertiary ...
