|
|
|
a central carbon connected to an amine group (NH2) and an opposing carboxyl group (COOH), with a variable group (denoted ‘R’) making each type unique
|
|
|
3 components-a pentose sugar, a phosphate group and a nitrogenous base
|
|
|
a long chain of hydrocarbons that may or may not contain double bonds, and have a carboxyl group on the end
|
|
|
primarily of C, H & O atoms in a common ratio-Cn(H₂O)n

Detailed explanation-1: -The R-group dictates the properties (size and structure) and nature of the amino acid (polarity). It determines if the amino acid is considered acidic, polar, nonpolar, basic, or neutral. The R-group can also help to predict the behaviour and the reactivity of the amino acid in a reaction.
Detailed explanation-2: -Each of the 20 amino acids has a specific side chain, known as an R group, that is also attached to the carbon. The R groups have a variety of shapes, sizes, charges, and reactivities. This allows amino acids to be grouped according to the chemical properties of their side chains.
Detailed explanation-3: -Amino acids have a central asymmetric carbon to which an amino group, a carboxyl group, a hydrogen atom, and a side chain (R group) are attached.
Detailed explanation-4: -There is also a hydrogen attached to the central carbon. The last substituent varies between amino acids and determines how the particular amino acid will be used in proteins. This variable group is known as the “R-group.” Only one amino acid, alanine, has a methyl group attached in the “R-group” position.
