How are glucose and galactose epimers?
Kindly describe in brief how this epimer is different from manose and glucose one.
Help please and thanks!
Answer:
hehe I needed some brianliest plz OK
Explanation:
Glucose and galactose are monosaccharides that differ from one another only at position C-4. Thus, they are epimers that have an identical configuration in all the positions except in position C-4. ... Glucose and galactose are epimers that do not differ in position C-5 but differ in position C-4.
Glucose and mannose are epimers that differ at the C-2 carbon, while glucose and galactose are epimers that differ at the C-4 carbon, as shown below. When a molecule such as glucose converts to a cyclic form, it generates a new chiral center at C-1.

I think that it would be better to have smaller cells because smaller cells takes less energy to transport waste and generally more efficient to control than larger cells. It is better to have smaller cells because larger and fewer cells takes up more nutrients, but doesn't cover as many surface area. In the end, smaller cells are more efficient, cover more surface area, and moves faster than bigger cells.
