In a lipid, the ratio of hydrogen to oxygen is ____
|
|
Greater than 2:1
|
|
|
2:1
|
|
|
4:6
|
|
|
1:1
|
Explanation:
Detailed explanation-1: -The three elements namely carbon, hydrogen, and oxygen present in carbohydrates are in the ratio of 1:2:1 respectively, this is why they are called carbohydrates. In lipids, the components are the same but the ratio is less for oxygen, so it is 1:2: less than one for C:H:O.
Detailed explanation-2: -For example, hydrogen and oxygen atoms combine in a ratio of 2:1 to form the compound water, H2O.
Detailed explanation-3: -Lipids have more carbon and hydrogen atoms than oxygen atoms. Fats are made of a glycerol (alcohol) and three fatty acid chains. This subunit is called a triglyceride. The fatty acid chains may be saturated (only single bonds between carbons) or unsaturated (contain at least one double bond).
