BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Organic compounds are large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen and nitrogen. Thus amongst the given options, ammonia is not an organic compound.

Detailed explanation-2: -Carbonic acid is not an organic acid.

Detailed explanation-3: -Carbon disulfide, also known as CS2, belongs to the class of inorganic compounds known as other non-metal sulfides. These are inorganic compounds containing a sulfur atom of an oxidation state of-2, in which the heaviest atom bonded to the oxygen belongs to the class of other non-metals.

Detailed explanation-4: -Organic compounds containing sulfur are termed as organosulfur compounds. They are commonly found in garlic (Allium sativum), and other sources include cruciferous vegetables such as bok choy, cabbage, and broccoli.
