BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Cystine contains two carboxylic groups and two amino groups because it is formed by two units of amino acids. Hence, cystine is diamino dicarboxylic amino acid while cysteine is monoamino monocarboxylic amino acid.

Detailed explanation-2: -benzene-1, 2-dicarboxylic acid is a dicarboxylic acid whose common name is Phthalic acid. Q. Write the common name, IUPAC name and formula of one monocarboxylic acid and one dicarboxylic acid.

Detailed explanation-3: -Note: This alanine has one amine group and one carboxyl group which is attached to the carbon of methyl group, so this alanine is considered as Monoamine monocarboxylic, and it is nonpolar, the systematic name of this alanine is 2 amino propionic acid.

Detailed explanation-4: -The term amino acid is short for -amino [alpha-amino] carboxylic acid. Each molecule contains a central carbon (C) atom, called the -carbon, to which both an amino and a carboxyl group are attached.
