1.4 Organic compounds | The chemistry of life | Siyavula
An organic compound is a compound whose molecules contain C, and usually at least one C-C or C-H bond. Very small carbon-containing molecules that do not follow the above rules, such as (text {CO}_ {2}) and simple carbonates, are considered inorganic. Life on earth would not be possible without carbon.

Onion is one of the richest sources of flavonoids that onion leaves contain 1,497.5 mg/kg of quercetin, 832.0 mg/kg of kaempferol, and 391.0 mg/kg of luteolin. Red wine is also a prominent source of flavonols (up to 30 mg/L). In addition, black tea contains up to 4.17 mg of quercetin/g in the human diet.
Carbohydrate
However, there is another type of five-carbon sugars that play different but crucial roles in the basic cell processes. An important example, one of the most important basic molecules is ribose with five carbons, thus formula C 5 H 10 O 5 (see Figure 12.6). Its main role is to form a structure element in nucleic acids and energy-storing substances.
Energy
In physics, energy (from Ancient Greek ἐνέργεια (enérgeia) ''activity'') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not …
