To address the challenge of identifying the majority of such «specialized metabolites» in any given plant, Dr. Nir Shahaf and other members of a team headed by Prof. Asaph Aharoni of Weizmann's Plant and Environmental Sciences Department created a database
of plant metabolites, called WeizMass.
WeizMass and MatchWeiz are not limited to the study
of plant metabolites but may also be used to investigate the biology of other living systems, including animal and human metabolism.

of metabolites, including phenolic acids.
Researchers at the Department
of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley have discovered that as

metabolites.
The main mechanisms attributed for biocontrol include: synthesis
of secondary
metabolites, such as 2,4 - diacetylphloroglucinol (2,4 - DAPG), hydrogen cyanide (HCN), pyoluteorin, pyrrolnitrin, phenazines, cyclic lipopeptides (CLP) and siderophores (6); production
of phytohormones, such as auxins, cytokinins and gibberellins; as well as nutrient solubilization traits (nitrogen, phosphorous, iron), which directly favors
plant growth and health (7).

It's at this point where many
of the antioxidant vitamins, minerals and phytonutrients found in
plants are helpful in stabilizing these intermediary
metabolites until they can undergo phase II liver detoxification and ultimately be converted into water soluble substance that can be excreted from the body via the stool or urine.
Such
plants are usually more nutrient - dense since they contain higher amounts
of vitamins, minerals, and secondary

plants.

Respiration («breathing») is inherently net - neutral with respect to CO2, and if one considered the pre-industrial age, the planet could support a large fauna (including pre - industrial / pre-agricultural humankind) whose breathing merely returned CO2 into the atmosphere, previously ingested (as
metabolites of carbohydrate) from
plants which pulled this CO2 out
of the atmosphere in the first place.
