For example, milk sugar (lactose) is a disaccharide made by condensation of one molecule of each of the monosaccharides glucose and galactose, whereas the disaccharide sucrose in sugar cane and sugar beet, is a condensation product of glucose and fructose. Maltose, another common disaccharide, is condensed from two glucose molecules. [7]
The Eagle Borax Works in Death Valley, California was established near Bennetts Well in 1882 by Isidore Daunet, J.M. McDonald, M. Harmon and C.C. Blanch to mine the borate deposits that Daunet discovered there in 1880. The partnership established the first borax works in the valley.
The Death Valley expedition was an 1891 expedition to discover the geographic distributions of plants (phytogeography) and animals in California's Death Valley. [1] It was the first of a series of expeditions funded by an 1890 act of the United States Congress. [1] The expedition included biologists, naturalists, botanists, and zoologists.
During the summer months, when it was too hot to crystallize borax in Death Valley, a smaller borax mining operation shifted to his Amargosa Borax Plant in Amargosa, near the present community of Tecopa, California. The Harmony Works remained under Coleman's operation until 1888, when his business collapsed.
The phenolic unit can be found dimerized or further polymerized, creating a new class of polyphenol. For example, ellagic acid is a dimer of gallic acid and forms the class of ellagitannins, or a catechin and a gallocatechin can combine to form the red compound theaflavin, a process that also results in the large class of brown thearubigins in tea.
The hottest temperature ever officially recorded on Earth was 134 F (56.67 C) in July 1913 in Death Valley, though some experts dispute that measurement and say the real record was 130 F (54.4 C ...
An additional type is galactoglucomannan found in soft wood with a mixed mannose/glucose β(1-4) backbone. Many mannans are acetylated and some from marine sources, have sulfate esters side chains. Yeast and some plants such as conjac and salep have a different type of mannans in their cell wall, with a α(1-6) linked backbone and α(1-2) and ...
As the temperature climbed to a record 128 degrees in Death Valley National Park, a group of motorcyclists was sickened by the heat, and one died.
