A __________ is an organic molecule that consists of C, H, O atoms in a ratio of 1:2:1.

Answers

Answer:

Molecule

Explanation:

Molecule 34

Final answer:

A carbohydrate is an organic molecule consisting of C, H, and O atoms in a 1:2:1 ratio, important for human biochemistry and found in various forms from simple sugars to complex polysaccharides.

Explanation:

An organic molecule that consists of carbon (C), hydrogen (H), and oxygen (O) atoms in a 1:2:1 ratio is known as a carbohydrate. Carbohydrates are essential biomolecules that come in various forms, such as sugars, starches, and fibers.

They have a general stoichiometric formula of (CH₂O)ₙ, where 'n' represents the number of carbon atoms in the molecule.

These organic compounds are a significant part of human biochemistry, consisting of carbon and hydrogen, and are essential for our diet and bodily functions.

Simple carbohydrates include monosaccharides like glucose and fructose, while complex carbohydrates include polysaccharides such as starch and cellulose.

The carbon skeleton of a carbohydrate provides a backbone to which other functional groups are bound, making them versatile in structure and function within living organisms.
