Vedclass · Answer

(B) Lipids are organic molecules composed primarily of carbon,hydrogen,and oxygen atoms. Unlike carbohydrates,which generally have a $1:2:1$ ratio of $C:H:O$,lipids contain a much higher proportion of carbon and hydrogen atoms relative to oxygen atoms. Because oxygen is highly electronegative and pulls electrons away from carbon and hydrogen,the high carbon-hydrogen content in lipids allows them to store significantly more energy per gram than carbohydrates. Therefore,lipids are characterized by having a higher carbon content and a lower oxygen content compared to carbohydrates.
