How does NH4SO4 affect water structure? What does this have to do with protein solubility? I thought the answer was that NH4S04 attracts H2O so the protein doesn't bind to H2O allowing the protein to bind to each other. But the answer given is, orders water locally to become more ice-like. Can someone explain?

The biosynthetic pathway for the two amino acides E and H is shown schematically in the Figure below: A W E 2 Z H How would this pathway change if C was mutated and non-functional?
Saccharide X, a sugar composed of repeating cellobiose and maltose, is a constituent of two glycoproteins, which are receptors that are found in a certain membrane. For the first glycoprotein, the saccharide is linked by a(1-2) linkages to three sialic acid residues, then O-linked to the glycoprotein. The other glycoprotein, on the other hand, has the saccharide linked by a B(1-3) bond also to three sialic acid residues, then also O-linked to the glycoprotein. The saccharide was cleaved from its sialic acid residues. The treatments and results are as follows: 1. hydrolysis by B(1-> 4) - disaccharide products 2. hydrolysis by a(1-> 4) - release of 2 disaccharide & 2 monosaccharide units. Show the structure of the saccharide.

If you discover a peptide that has a glycine at the N-terminus what can that tell you about peptide processing? O The peptide hormone must be processed from a precursor since all new proteins have a methionine at the N-terminus The N-terminus must be processed by methylation by adoMet O The peptide must be from bacteria since all bacterial peptides begin with the amino acid glycine The N-terminus is phosphorylated by the action of an N-terminal kinase
