What does OC mean in CHEMISTRY

Organic Carbon (OC) refers to carbon that has been part of a living organism at any point in its history. This can include plants, animals and microorganisms that have either died or been decomposed over time.

Organic Carbon comes from sources such as fossil fuels, decomposition of organic matter and photosynthesis by green plants in the atmosphere.

Organic Carbon is essential for life on Earth as it helps to stabilize climate systems by acting as a sink for atmospheric CO2 and providing energy to living organisms through its multiple forms such as carbohydrates, proteins and fats. It also provides necessary materials for construction for many organisms including humans. Additionally, OC contributes to soil fertility by improving nutrient cycling and promoting growth of healthy plant populations.

There's approximately 610 gigatons (Gt) of organic carbon stored in the atmosphere currently which accounts for 0.5% - 2% of total atmospheric carbon dioxide (CO2). This figure has been estimated based on concentrations detected by a number of studies including satellite observations over recent decades.

Too much or too little organic carbon can affect global biosphere processes leading to changes to our climate systems such as extreme weather events or biodiversity losses due abnormal temperatures or habitats destruction respectively. Therefore, maintaining a sufficient amount is essential for maintaining balanced environmental conditions on Earth.
