Michiyo Tsujimura
was a Japanese agricultural scientist and biochemist whose research focused on the components of green tea. She was the first woman in Japan to receive a doctoral degree in agriculture. Early life Tsujimura was born in 1888 in what is now Okegawa in Saitama Prefecture. She attended Tokyo Prefecture Women's Normal School, graduating in 1909, and the Division of Biochemical Science at Tokyo Women's Higher Normal School. There, she was taught by the biologist Kono Yasui, who inspired in Tsujimura an interest in scientific research. She graduated in 1913 and became a teacher at Yokohama High School for Women in Kanagawa Prefecture. In 1917, she returned to Saitama Prefecture to teach at Saitama Women's Normal School. Career and research Tsujimura's research career began in 1920 when she joined Hokkaido Imperial University as a laboratory assistant.

Timeline Of Women In Science
This is a timeline of women in science, spanning from ancient history up to the 21st century. While the timeline primarily focuses on women involved with natural sciences such as astronomy, biology, chemistry and physics, it also includes women from the social sciences (e.g. sociology, psychology) and the formal sciences (e.g. mathematics, computer science), as well as notable science educators and medical scientists. The chronological events listed in the timeline relate to both scientific achievements and gender equality within the sciences. Ancient history * 1900 BCE: Aganice, also known as Athyrta, was an Egyptian princess during the Middle Kingdom (about 2000–1700 BCE) working on astronomy and natural philosophy. *c. 1500 BCE: Hatshepsut, also known as the Queen Doctor, promoted a botanical expedition searching for officinal plants. * 1200 BCE: The Mesopotamian perfume-maker Tapputi-Belatekallim was referenced in the text of a cuneiform tablet.

Google Doodle
A Google Doodle is a special, temporary alteration of the logo on Google's homepages intended to commemorate holidays, events, achievements, and notable historical figures. The first Google Doodle honored the 1998 edition of the long-running annual Burning Man event in Black Rock City, Nevada, and was designed by co-founders Larry Page and Sergey Brin to notify users of their absence in case the servers crashed. Early Marketing employee Susan Wojcicki then spearheaded subsequent Doodles, including an alien landing on Google and additional custom logos for major holidays. Google Doodles were designed by an outside contractor until 2000, when Page and Brin asked public relations officer Dennis Hwang to design a logo for Bastille Day. Since then, a team of employees called "Doodlers" have organized and published the Doodles. Initially, Doodles were neither animated nor hyperlinked—they were simply images with tooltips describing the subject or expressing a holiday greeting. D ...

Gallocatechin
Gallocatechol or gallocatechin (GC) is a flavan-3-ol, a type of chemical compound including catechin, with the gallate residue being in an Cis-trans isomerism, isomeric trans position. This compound possesses two epimers. The most common, (+)-gallocatechin (GC), CAS number 970-73-0, is found notably in green tea. The other enantiomer is called (-)-gallocatechin or ''ent''-gallocatechin. It was first isolated from green tea by Michiyo Tsujimura in 1934. Epigallocatechin is another type of catechin, with the gallate residue being in an Cis-trans isomerism, isomeric cis position. It can be found in Hypericum perforatum, St John's wort.

Tannin
Tannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids. The term ''tannin'' (from Anglo-Norman ''tanner'', from Medieval Latin ''tannāre'', from ''tannum'', oak bark) refers to the use of oak and other bark in tanning animal hides into leather. By extension, the term ''tannin'' is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with various macromolecules. The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation (acting as pesticides) and might help in regulating plant growth. The astringency from the tannins is what causes the dry and puckery feeling in the mouth following the consumption of unripened fruit, red wine or tea. Likewise, the destruction or modification of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
