Which of the following is not found in a lipid? a. glycerol b. carbon c. fatty-acids d. amino acids

D. amino acids

Explanation:

Hello,

Lipids are mainly composed by carbon atoms as long as they are organic compounds. In addition, glycerides which are types of lipids are composed by glycerol (polyols molecules). Finally, fatty-acids, are long-chained carboxylic acids which are also present in lipids. Thus, amino acids are excluded from the lipids structures.

Best regards.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
