Signal transduction

...lude heterotrimeric G protein , small GTPases , cyclic nucleotides , such as cyclic AMP (cAMP) and cyclic GMP (cGMP), calcium ion , phophoinositide derivatives, such as Phosphat...

Red Queen

... Red-Queen-type theory that organisms are running cyclic arms races with their parasites can explain the utility of sexual reproduction at the level of the gene by positing that the role of sex is to preserve genes which are currently disadvantageous, but which will become advantageous against the backg...

Purine

...her important biomolecules, such as ATP , GTP , cyclic AMP , NADH , and coenzyme A . Metabolism Many organisms have metabolic pathways to synthesize and break down purines. Purines are biologically synthesized as nucleotides (bases attached to ribose ). Both adenine and guanine are derived...

Glucose

... due to glucose's preference for the less reactive cyclic isomer . Nevertheless, many of the long-term complications of diabetes (e.g., blindness, kidney failure, and peripheral neuropathy) are probably due to the glycosylation of proteins. The chain form of D -Glucose In respiration, throug...

Enzyme

Dialysis

...eds no machine and can be done at home. Continuous cyclic peritoneal dialysis (CCPD) uses a machine and is usually performed at night when the person is sleeping. Intermittent peritoneal dialysis (IPD) uses the same type of machine as CCPD, but is usually done in the hospital because treatment takes longer....

Biomechanics

... soft tissues can be preconditioned by repetitive cyclic loading to the extent where the stress-strain curves for the loading and unloading portions of the tests nearly overlap. Nonlinear Theories Hooke's law is linear, but many, if not most problems in biomechanics, involve highly nonlinear behavio...
