Question

The general structure of all amino acids are same except for ___________
a.Lysine
b.Glycine
c.Proline
d.Alanine

Answer 1

Answer:

Proline because in general , all a-amino acids consists of an amino group, a hydrogen atom and

Answer 2

Answer:

B) Glycine

Explanation:

• All amino acids include 5 basic parts:
• a central carbon atom
• a hydrogen atom
• an amino group, consisting of a nitrogen atom and two hydrogen atoms
• a carboxyl group, consisting of a carbon atom, two oxygen atoms, and one hydrogen atom
• an R-group or side chain, consisting of varying atoms
• The R-group is what makes every amino acid special. Each of the 20 amino acids has a different side-chain structure. Side chains contain mainly hydrogen, carbon, and oxygen atoms. Some amino acids have sulfur or nitrogen atoms in their R-groups.

Each amino acid has a name, abbreviation, and special side-chain make-up.

• In general, all α-amino acid consists of an amino group, a hydrogen atom, and a distinctive side chain, all bonded to α-carbon. ... All amino acids have chiral carbon except glycine and hence they are optically active.
