AMINO ACIDS = Building blocks of protein = There are 20 different types of amino acids - Each amino acid has an amine group and a carboxylic group, therefore can react to both acids and bases. General Pormula of amino acids HaNC-COOH R = Amino acids can also form a double charge ion whiten the hydragen ion on the carboxylic group is accepted by the amine group. These compounds are called zwitterions - Zwitterions are elecmorally neutral because their charges balance Bach other. H3N C-000 = When amino acids react with acids, they act as bases and the Hila grap accepts the prot HaN-C-COOH + H+ H3H+ R と C-COOH R When amino acids react with bases they act as acids and the carboxylic acid donates the proton H H2N-C-COOH + OH H2N-CCOO + H2O R R Mosa amino acids ave neutral, however, some are basic or acidic, depending on the number of amine or carboxylic graps When the number of Nils groups are move the amino acid becomes When the number of Nils groups are less, the amino acid beromes acidic Different amino acids exist in aqueous sellutons at certain PH salues LD These PH values are referred to as iscelectric points Lo molecule is electrially necival- All amino acids, except glycine, have a chiral contre making. them optically achive. Therefore, synthesis of amino acids produces a receanic mixture
