The functional groups found in amino acids are essential components that define their chemical properties. Here is a breakdown of the functional groups present in all amino acids:
1. Amino group: This functional group consists of a nitrogen atom bonded to two hydrogen atoms, represented as -NH2. It is found in all amino acids, giving them their basic nature.
2. Carboxyl group: The carboxyl group is composed of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group (-COOH). This group is also present in all amino acids, providing them with acidic properties.
Therefore, the correct functional groups found in all amino acids are the amino group and the carboxyl group. The phosphate group and methyl group are not typically part of the structure of amino acids.
