He studied physics and chemistry in Berlin. He became interested in sugar refining through his stepfather. At the age of 20, Achard entered the "Circle of Friends of Natural Sciences" and met Andreas Sigismund Marggraf , then director of the physical classes at the Royal Academy of Sciences.
Description: A classic general textbook for an undergraduate course in physical chemistry Importance: This book is not only a good introduction to the subject, it was very different from earlier texts and altered the way physical chemistry was taught. The first edition was very widely used where English is the language of instruction.
Sucrose is formed by plants, algae and cyanobacteria but not by other organisms. Sucrose is the end product of photosynthesis and is found naturally in many food plants along with the monosaccharide fructose. In many fruits, such as pineapple and apricot, sucrose is the main sugar. In others, such as grapes and pears, fructose is the main sugar.
The average American consumed approximately 37.8 lb (17.1 kg) of high-fructose corn syrup in 2008, versus 46.7 lb (21.2 kg) of sucrose. [ 70 ] In recent years it has been hypothesized that the increase of high-fructose corn syrup usage in processed foods may be linked to various health conditions , including metabolic syndrome , hypertension ...

Sweet-tasting, water-soluble carbohydrates This article is about the class of sweet-flavored substances used as food. For common table sugar, see Sucrose. For other uses, see Sugar (disambiguation). Sugars (clockwise from top-left): white refined, unrefined, brown, unprocessed cane Sugar ...
Therefore, the molecular structure of a simple monosaccharide can be written as H(CHOH) n (C=O)(CHOH) m H, where n + 1 + m = x; so that its elemental formula is C x H 2x O x. By convention, the carbon atoms are numbered from 1 to x along the backbone, starting from the end that is closest to the C=O group. Monosaccharides are the simplest units ...
Discovered in 1976, the FDA approved sucralose for use in 1998. [32] Most of the controversy surrounding Splenda, a sucralose sweetener, is focused not on safety but on its marketing. It has been marketed with the slogan, "Splenda is made from sugar, so it tastes like sugar." Sucralose is prepared from either of two sugars, sucrose or raffinose.
It has a purity higher than 99.7%. [1] Its molecular formula is C 12 H 22 O 11. [2] White sugars produced from sugar cane and sugar beet are chemically indistinguishable: it is possible, however, to identify its origin through a carbon-13 analysis. [1]
