From a nucleic acid code to an amino acid code
A beta-amino acid is an amino acid which has the amino and carboxylic functional groups attached to adjacent carbon atoms.
An amino group and an R group
amino acid
Proteins and enzymes
The R-group (side-chain), is what gives each amino acid its unique properties and affects how a protein folds.
The variable of amino acid is called the R group.
The monomer is the individual amino acid following the amino acid assignation (NH2CHCOOHR) where the R group determines which amino acid it is - and is the variable unit.
The monomer is the individual amino acid following the amino acid assignation (NH2CHCOOHR) where the R group determines which amino acid it is - and is the variable unit.
The variable R group of each amino acid is attached to the carbon alpha to, or immediately adjacent to, the carbon bearing the carboxylic acid functionality.
When two amino acids are linked with a peptide bond it is called a dipeptide, when the third amino acid come and joins them it will be then a tripeptide.
(NH2)-(RCH)-(COOH) = (amino group)-(central carbon + hydrogen + variable side group)-(carboxyl group)

The monomers of proteins are known as amino acids....A further explanation:Do not confuse amino acids with nucleic acids. Nucleic acids are DNA and RNA and are another one of the BIG 4 macromolecules that are needed to survive.The 4 are:Carbohydrates (monomer: monosaccaride)Proteins (monomer: amino acids)Lipids (monomer: fatty acids)Nucleic Acids (monomer: nucleotides)
proline is not an amino acid it is an imino acid
Did you mean: amino acid, this is a general name for hydrocarbon chain molecules with at least one amino group (-NH2) and one carboxyl group (-COOH). There are up to 20 different amino acid monomers present in proteins.
