- Adenine — A fundamental purine nitrogenous base, with a heterocyclic structure composed of two condensed rings, an essential component of nucleic acids (DNA and RNA). It plays a crucial structural role in storing and transmitting genetic information through specific hydrogen bonds with thymine or uracil, being also a key element in molecules vital for cellular energy metabolism, such as ATP.
- Adenosine-phosphoric — Relating to compounds resulting from the combination of adenosine with one or more phosphoric acid groups, playing a fundamental role in cellular energy metabolism. In a structural sense, it describes nucleoside-phosphoric acids (such as ATP, ADP, or AMP) that act as primary carriers of chemical energy and mediators in the biochemical signaling processes of living organisms.
- Adenosine — A fundamental purine nucleoside formed by the structural binding of an adenine molecule with a ribose molecule. This essential component plays crucial biological roles as a structural element in major bioenergetic compounds, such as adenosine triphosphate (ATP), while simultaneously functioning in the nervous system as a neuromodulator with strong inhibitory effects regulating the sleep-wake cycle, and as an antiarrhythmic agent in emergency cardiology.
- Anabolism — A fundamental phase of metabolism, characterized by the totality of biochemical processes of assimilation and biosynthesis through which the organism transforms simple nutrients from the environment into complex macromolecular compounds (proteins, nucleic acids, glycogen, and tissues). This cellular structural phenomenon requires a direct consumption of chemical energy, supplied by the breakdown of ATP molecules.
- Alactic — Not producing lactic acid, preventing its accumulation, or pertaining to a metabolic process carried out structurally without lactate generation. In exercise physiology, the term qualifies anaerobic alactic energy metabolism, wherein the energy required for short-duration explosive muscle contractions is supplied exclusively by phosphocreatine breakdown, without the intervention of anaerobic glycolysis.
