Fatty acids are long ______ chains and are components of triglycerides.Multiple choice question.nucleotideamino acidglucosecarbon

The correct answer for the blank in the sentence "Fatty acids are long ______ chains and are components of triglycerides." is "carbon."

Explanation

Fatty acids are organic molecules characterized by long hydrocarbon chains that consist primarily of carbon (C) and hydrogen (H) atoms. These chains can vary in length and can be saturated (single bonds between carbon atoms) or unsaturated (one or more double bonds present). Fatty acids play a crucial role in biology as they are the building blocks of triglycerides, which are a form of fat stored in the body. Triglycerides are composed of three fatty acid molecules attached to a glycerol backbone. Other options like nucleotide, amino acid, and glucose do not fit in this context, as they refer to different types of biomolecules (nucleotides are the building blocks of nucleic acids, amino acids are the building blocks of proteins, and glucose is a simple sugar).

Therefore, the answer is:

Final Answer

carbon
