Malic

Malic

(Science: chemistry) Pertaining to, or obtained from, apples; as, malic acid. Malic acid, a hydroxy acid obtained as a substance which is sirupy or crystallized with difficulty, and has a strong but pleasant sour taste. It occurs in many fruits, as in green apples, currants, etc. It is levorotatory or dextrorotatory according to the temperature and concentration. An artificial variety is a derivative of succinic acid, but has no action on polarized light, and thus malic acid is a remarkable case of physical isomerism.

Origin: L. Malum an apple: cf. F. Malique.

Need help with metabolism

... FADH2 is used in oxidative phosohorilation. 3. some substances can enter the krebs cycle directly, if they are intermediates of the krebs cycle(malic acid, citric acid etc). however, this is done by the cell only to increase/decrease the number of intermediates, therefore as a regulatory mechanism. ...

C3 and C4 plants

... is wrong. All plant assimilation types(C3, C4 and CAM) undergo the Calvin cycle. C4 and CAM plants have an additional cycle witch fixes CO2 into malic acid(usually) first and then "gives" it to Rubisco and runs the Calvin cycle. The two types of plan ts differ in 2 main ways: 1. C4 ...

... a 3-C chemical that is converted into oxaloacetic acid (OAA, a 4-C chemical) when carbon dioxide is combined with PEP. The OAA is converted to Malic Acid and then transported from the mesophyll cell into the bundle-sheath cell, where OAA is broken down into PEP plus carbon dioxide. The carbon ...
