Polysaccharides polynucleotides and polypeptides are all syn

Polysaccharides, polynucleotides, and polypeptides are all synthesized from monomers into polymers by: Why are phospholipids so different from simple fats and steroids? Draw a typical diagram of a cell membrane, showing a bilayer, peripheral, and integral proteins. An organic molecule contains a ribose, a nitrogenous base, and a phosphate group. This is the general structure of: The primary structure of a protein is determined by: Chemical tests on a solution showed a mixture of glycosidic bonds and peptide bonds present in the solution. What 2 types of macromolecules are likely to be in this solution? A cell extract was found to have a lot of nucleic acid, but it was missing \'thymine\'. What kind of nucleic acid was this? What kind of bonds will shape a protein into either an alpha helix or a beta pleated sheet? Amylase can hydrolyze starch down to maltose but not cellulose. Why not? Both molecules are polymers of glucose. Plant oils, such as peanut oil, can be \'solidified\' by hydrogenation of in the long-chain fatty acids. This gets rid of the oil layer in a jar of peanut butter, but creates \'peanut lard\'!

Solution

1 dehydration reaction is the procedure by which polysaccharides, polypeptides and polynucleotides are synthesized.

2.simple fats are composed of triglycerides and are hydrophobc by nature whereas steroids have a carbon backbone attached with 4 rings and is hydrophobic again.

Whereas phospholipids have 2 fatty acids,glycerol, a phosphate group and a polar group

The polar head region is hydrophillic whereas the other part is hydrophobic.

So the phospholipids arrange themselves in a bilayer structure as soon as they are placed in water..thats why they a are different from simple fats and steroids.

3. This is a structure of nucleic acid.

4.primary structure of protein is determined by sequence of amino acid.

Thank you.
