B1.1.4—Form and function of monosaccharides question 1
[Maximum number: 3]
A wide variety of organic compounds are used by living organisms.
Draw a diagram to show the ring structure of D-ribose.
a. ring with four carbons and one oxygen atom;
b. CH2OH attached to C 4 ;
c. OH and H attached by single bonds to C 1, C 2 and C 3 with OH facing downwards on C2 and C3;
Numbering of carbons not required for mpa.
Carbons in the ring can be shown as a junction of single bonds without the letter C, but oxygen must be shown as O.
For mpc OH can face up or down.
