In amino acids, what is the name of the monomer that makes up proteins? The first amino acid inserted into a new polypeptide chain in eukaryotic cells is always: A.Glycine B.Methionine C.Alanine D.Serine E.Adenosine...
There are two principal ways that a garment is made waterproof, either through a membrane finish which is bonded to the fabric or a chemical finish applied directly to the fabric. The waterproof membrane consists of millions of tiny pores that are hundreds of times smaller than a molecule of ...
The dehydration of cyclohexanol is performed by removing the OH group for the molecule to be less polar, thus soluble in hexane. The current process used is fractional distillation. In this method, cyclohexanol is heated until it reaches its boiling point at 190 °C. The product is then colle...
Decide which of the following bonds is least polar on the basis of electronegativities of atoms: H-S, Si-Cl, N-Cl. Which molecule or molecules can form hydrogen bonds with water? Select all that apply. a. CH_3CH_2OH b. CH_3(CH_2)_3COOH c....
aI would suppose that toluene is a solvent which would solve the molecule very well and ratio of hexane should be increased or even toluene dismissed. As an alternative to hexane you could try methylcyclohexane, acetone or MTBE. Those solvents I would choose next. Let us see then the differen...
s electronegativity increases with its mass. This is particularly the case for Mu–H molecules, which are decidedly polar: Mud+–Hd-. That in itself forces the issue of whether Mu is really like light hydrogen or needs its own slot in the periodic table: Goli and Shahbazian raise the ...
23) What is a fat or triacylglycerol? A) a protein with tertiary structure B) a molecule formed from three alcohols C) a lipid made of three fatty acids and glycerol D) a carbohydrate with three sugars E) a kind of lipid that makes up much of the plasma membrane B) uracil. C) ...
