Question

All α-amino acids contain, all of the following except


Carboxyl group


α-Carbon


Hydrogen


Methyl group

Answer 1

Answer:

hydrogen

Explanation:

bcoz the alpha- amino acid has all except the hydrogen. Substiutent of methane occupys the valence site

Answer 2

Answer:

All α-amino acids contain, all of the following except a Methyl group.

Explanation:

What are α-amino acids:

• Amino acid is an abbreviation for -amino [alpha-amino] carboxylic acid.
• α-Amino acids are simple molecules that are made of a central C-atom, labelled Ca, that is bound to a primary amine group NH2 and to a carboxylic group COOH.
• Each molecule has a central carbon (C) atom, referred to as the α-carbon, to which an amino and carboxyl group are attached.
• A hydrogen (H) atom and the R group usually fulfil the remaining two bonds of the -carbon atom.
