The acid has been synthesized, as has also the inactive form of methylethylacetic acid; this modification is split into its optical antipodes by crystallization of its brucine salt.
It has been synthesized by E.
87, p. 325) synthesized it by acting with benzoyl chloride on zinc glycocollide.
Brown and Morris in 1892 advanced strong reasons for thinking that cane-sugar, Ci2H22O11, is the first carbohydrate synthesized, and that the hexoses found in the plant result from the decomposition of this.
Water and carbonic acid are synthesized, under the action of sunlight, to form sugar, starch or some other carboh y drate and this is then combined with simple nitrogenous salts to form proteid.
