Answer: Proteins are known as biomolecules and biomolecules are made of the elements Carbon, Hydrogen, Nitrogen, and Oxygen and the monomers of proteins are known as amino acids.
The water molecule is a polar molecule which would mean that there is an uneven distribution of charges. Each molecule of water has partial positive and partial negative end. The partial positive charges is found in the H atoms while the partial negative is at the O atom. This is due to the the unequal sharing of the electrons.
Answer:
The stereochemical configuration of sorbitol is 2S,3R,4R,5R with an S-configuration at the 2-position.
Explanation:
In the absence of a diagram given of the marked atoms, this is a general information of the stereochemistry of sorbitol. Hopefully it serves as a guide for the answer
- The groups attached to the chiral carbons are assigned a priority.
- Then you should identify the atoms attached to the stereo-centre and priotize them in order of increasing atomic numbers (highest atomic number will take the highest priority 1 and so on).
- Then take note of the direction in which the priorities decrease (from 1 -2 - 3 - 4 ...). If it decreases in a clockwise manner the stereo-center is labelled as R if it decreases in a counterclockwise manner, the stereo-Centre is labelled as S.
Sorbitol has an IUPAC name called (2S,3R,4R,5R)-hexane-1,2,3,4,5,6-hexol which is based on its stereochemical configuration
