Consider the sugar below. Which term best describes this sugar? disaccharide monosaccharide polysaccharide saccharide
nekit [7.7K]

oh wait i wrote whole paragraphs let me fix this

okay so you mean this ?

a term for disaccharides would be double sugar or boise!

monosaccharides are simple sugars soluble in water. any class of sugars like glucose.

polysaccharide is starch, cellulose, or glycogen. with molecules together. a carbohydrate.

saccharide knows as to the term structure of carbohydrates. carbohydrates are plain simple? organic compounds that are aldehyde or ketone functional group. with the general chemical formula of carbohydrates is c (H O)

The lipid portion of a typical bilayer is about 30 Å thick. a) Calculate the minimum number of residues in an α-helix required t
Mrrafil [7]

Answer:

a) The minimum number of residues in alfa helix to span 30 Å, is 20 residues

b) The minimum number of residues in a Beta sheet to span 30 Å, is 8.6 residues.

c) Should be better if you show an image to do this question.

d) Look answer below.

Explanation:

a) Due to every 5,4 Å there are 3,6 residues. So doing the calculus give us 20 residues.

b)  That’s it because every 7 Å there are 2 residues

c) First of all, is important to know that the residues of a protein define the secondary structure due to intermolecular and intramolecular interactions. Taking in account that the membrane bilayer has a lipid interior α-helical domains which are hydrophobic principally are embedded in membranes by hydrophobic interactions with the lipid interior of the bilayer favored by Van der Waals interactions and probably also by ionic interactions with the polar head groups of the phospholipids.

What information does the potential energy diagram reveal about a reaction?
Marina CMI [18]

Answer: It shows whether the reaction is exothermic or endothermic.

Explanation:

  • If the potential energy of the products is greater than that of the reactants, then the reaction is exothermic.
  • If the potential energy of the reactants is greater than that of the products, then the reaction is endothermic.
