The typical ratio of oxygen to carbon in a carbohydrate molecule is approximately 2:1. Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen, generally following the formula \(C_x(H_2O)_y\). This indicates that for every carbon atom present, there are usually two hydrogen atoms and one oxygen atom. This ratio is consistent across various types of carbohydrates, including sugars and starches, and is fundamental to their structure and function. Carbohydrates serve as essential energy sources for living organisms and play important roles in cellular processes.
