|
How can you tell if a chemical formula is a lipid or a carbohydrate?
|
|
only carbohydrates have carbon, hydrogen, and oxygen
|
|
|
carbohydrates will have a 1 carbon to 1 water molecule ratio
|
|
|
only lipids have carbon, hydrogen, and oxygen
|
|
|
you can’t tell the difference, because they both have carbon hydrogen, and oxygen.

Explanation:
Detailed explanation-1: -Carbohydrates (carbo-= “carbon”; hydrate = “water”) contain the elements carbon, hydrogen, and oxygen, and only those elements with a few exceptions. The ratio of carbon to hydrogen to oxygen in carbohydrate molecules is 1:2:1.
Detailed explanation-2: -Carbohydrates and lipids both contain carbon (C), hydrogen (H), and oxygen (0); proteins contain these three elements plus one or more from nitrogen (N), sulphur (S) and phosphorous (P).
Detailed explanation-3: -Carbohydrates can be represented by the stoichiometric formula (CH2O)n ( CH 2 O ) n, where n is the number of carbons in the molecule. Therefore, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules.
