Galactose
Yes, lead can be found in its pure form in nature. It is a naturally occurring element that is commonly found in the Earth's crust.
lactose is a naturally occurring sugar, and has all the same benefits as any other form of glucose.
Yes. It is found in rocks, and has the chemical formula CaCO3 . It's a form of limestone.
Yes, ribose is found in RNA (ribonucleic acid) as the sugar component of the nucleotides that make up the RNA backbone. In DNA (deoxyribonucleic acid), another naturally occurring nucleic acid, the sugar component is deoxyribose, which is a slightly modified form of ribose with one less oxygen atom.
Is the food
Copper sulphate found naturally in the Earth's crust is typically in the form of chalcanthite.
sugar can be found naturally in almost all fruits and in a tall, fibrous plant called sugar cane. It also grows naturally in its crystal form on certain types of rocks.
Sucrose would only be found in milk if sugar were added to milk. However lactose occurs naturally in dairy products, and is its own form of sugar.
If you mean a naturally occurring element, yes. However it is reactive and therefore not usually found in the pure metal form, instead it is found in compounds as ore.
The term is "minerals." Few elements are found in their pure elemental form, and they are mostly metals.
Naturally occurring (it is an element), the metal occurs naturally in its pure, free form (native silver), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite.
radon is a noble gas, so it does not form compounds.
