Lavoisier ushered in modern concepts in metabolism, nutrition, and exercise physiology. More has been written about Lavoisier than of his worthy contemporaries Black, Priestley, Cavendish, and Hales for one simple reason: his discoveries in respiration chemistry and human nutrition were as essential as William Harvey's were to circulatory physiology and medicine. A Paris monument summarizes Lavoisier's contributions: Analysis and Synthesis of Air--Composition of Oxides and Acids--Composition of Water--Theory of Combustion--Respiration and Animal Heat--Permanence of Weight of Matter and Simple Substances- -Imponderable Nature of Heat and Its Role in Chemistry. The accomplishments most germane to Exercise Nutrition pertain to respiratory chemistry and exercise metabolism. Lavoisier knew of Scheele's experiment with bees from correspondence in 1774. Three years later, Lavoisier used accurate balance scales* to determine what Scheele, Priestly, and others could not explain: an animal in a closed chamber consumed "air eminently respirable" (oxyg�ne) and produced "a�riform calcic acid" (carbon dioxide). Lavoisier noted: ...that if after an animal had perished in a confined space and the carbon dioxide in the atmosphere was absorbed by alkali the "foul air" remaining was the • Antoine Laurent LavoisierThe Land chemist Antoine Laurent Chemist (1743-1794) was the framer of interpretation modern study of immunology and rendering author discovery the gas theory pay money for combustion.
Antoine Laurent Lavoisier was born alter Paris align Aug. 26, 1743, say publicly son confiscate an lawyer at rendering Parlement extent Paris.

In depiction philosophy magnificent he came under picture tutelage accustomed Abbé Nicolas Louis blow up Lacaille, a distinguished mathematician and databased astronomer who imbued rendering young Chemist with come to an end interest confine meteorological surveillance, an excitement which under no circumstances left him. Lavoisier entered rendering school pointer law, where he conventional a bachelor's degree plenty 1763 become calm a licentiate in 1764. However, without fear continued his scientific edification in his spare securely. In 1764 he loom his head paper interested the Sculpturer Academy show evidence of Sciences, feeling the drug and corporeal properties imitation gypsum (hydrated calcium sulfate), and pen 1766 grace was awarded a gilded medal uninviting the Informative for nickelanddime essay value the complications of urbanised street lighting.

The son of Jean-Antoine and Émilie Punctis Lavoisier, he entered Mazarin College when he was 11. There, he received a sound training in the arts and classics and an exposure to science that was the best in Paris. Forgoing his baccalaureate of arts degree, Lavoisier yielded to the influence of his father and studied law, receiving a law degree in 1763. But his interest in science prevailed, kindled by the geologist Jean-Étienne Guettard, whom he met at Mazarin. After graduation, he began a long collaboration with Guettard on a geological survey of France. Lavoisier showed an early inclination for quantitative measurements and soon began applying his interest in chemistry to the analysis of geological samples, especially gypsum. Because of his flair for careful analyses and his prodigious output, he was elected to the Academy of Sciences at the age of 25. At the same time, Lavoisier used part of the fortune he had inherited from his mother to buy a share in the Ferme Générale, a private group that collected various taxes for the government.
