As a result, they rely on lactic acid fermentation to provide the majority of their energy needs. [23] Adaptations in particular in the turtle's blood composition and shell allow it to tolerate high levels of lactic acid accumulation. In the anoxic conditions where fermentation is dominant, calcium levels in the blood plasma increase. [23]
Congenital lactic acidosis is a rare disease caused by mutations in mitochondrial DNA (mtDNA) that affect the ability of cells to use energy and cause too much lactic acid to build up in the body, a condition called lactic acidosis.
Pyruvate carboxylase deficiency is an inherited disorder that causes lactic acid to accumulate in the blood. [2] High levels of these substances can damage the body's organs and tissues, particularly in the nervous system. Pyruvate carboxylase deficiency is a rare condition, with an estimated incidence of 1 in 250,000 births worldwide.
An elevated anion gap (i.e. > 16 mmol/L) indicates the presence of excess 'unmeasured' anions, such as lactic acid in anaerobic metabolism resulting from tissue hypoxia, glycolic and formic acid produced by the metabolism of toxic alcohols, ketoacids produced when acetyl-CoA undergoes ketogenesis rather than entering the tricarboxylic (Krebs ...
As a result, propionyl-CoA, propionic acid, ketones, ammonia, and other toxic compounds accumulate in the blood, causing the signs and symptoms of propionic acidemia. Hyperammonemia develops due to the inhibitory effects of propionyl-CoA on N-acetylglutamate synthase , indirectly resulting in slowing of the urea cycle .
Hyperprolinemia can also occur with other conditions, such as malnutrition or liver disease. In particular, individuals with conditions that cause elevated levels of lactic acid in the blood, such as lactic acidemia, are likely to have elevated proline levels, because lactic acid inhibits the breakdown of proline.

MELAS is a condition that affects many of the body's systems, particularly the brain and nervous system (encephalo-) and muscles (myopathy). In most cases, the signs and symptoms of this disorder appear in childhood following a period of normal development. [4]
A lactic acid buildup around muscles can trigger cramps; however, they happen during anaerobic respiration when a person is exercising or engaging in an activity where the heartbeat rises. Medical conditions associated with leg cramps are cardiovascular disease, hemodialysis, cirrhosis, pregnancy, and lumbar canal stenosis.
