Taiwan-born chemistry professor Lee Yuan-chuan (
A member of Academia Sinica, Lee will receive the Claude S. Hudson Award in Carbohydrate Chemistry from the American Chemistry Association (ACA) in a presentation ceremony slated for April 3 in San Diego, California, ACA sources said.
Lee, elder brother of Academia Sinica President Lee Yuan-tseh (李遠哲), will be the only award winner in carbohydrate chemistry at this year's ACA National Awards and the only Chinese to receive an ACA national award this year.
ACA sources said 68-year-old Lee, a professor at Johns Hopkins since 1965, was chosen because his "persistent efforts have enabled significant advances in the understanding of glycoconjugates such as glycoproteins and glycolipids."
Born in Taiwan, Lee earned a master's degree in agricultural chemistry from National Taiwan University in 1957. He obtained a doctorate in biochemistry from the University of Iowa in 1962. His graduate thesis was on the subject of carbohydrate structure of chicken ovalbumin.
His thesis, as well as postgraduate work at the University of California, Berkeley on the subject of Mycobacterium gly-colipids and lipopoly-saccharides, motivated Lee to devote himself to the study of glycobiology and glycosciences, according to the ACA.
Lee's research yielded many insights. For instance, he found ways to analyze both qualitatively and quantitatively the composition of glycoconjugates and also how to determine their structure. Along the way, ACA sources said, Lee developed one of the first automated sugar analyzers, which consisted of a cation-exchange column for amino sugars and an anion column for neutral sugars in the 10-nmol range.
These inventions eventually evolved to the form of HPAEC (high-performance anion-exchange chromatography), which is faster and more sensitive. HPAEC is now a standard instrumentation in most carbohydrate research laboratories.
Using such analytical tools, Lee established the structures of many N- and O-linked glycans. He was the first to put forth the concept of "core structure" for the N-glycoside, according to an academic familiar with Lee's work.
Lee is an artist when he is not working with chemistry. He paints, writes and plays cello, viola and violin. One of his works, written in Japanese, was cited by Japanese literary circles as one of the best 60 writings of the year some twelve years ago.
ENDEAVOR MANTA: The ship is programmed to automatically return to its designated home port and would self-destruct if seized by another party The Endeavor Manta, Taiwan’s first military-specification uncrewed surface vehicle (USV) tailor-made to operate in the Taiwan Strait in a bid to bolster the nation’s asymmetric combat capabilities made its first appearance at Kaohsiung’s Singda Harbor yesterday. Taking inspiration from Ukraine’s navy, which is using USVs to force Russia’s Black Sea fleet to take shelter within its own ports, CSBC Taiwan (台灣國際造船) established a research and development unit on USVs last year, CSBC chairman Huang Cheng-hung (黃正弘) said. With the exception of the satellite guidance system and the outboard motors — which were purchased from foreign companies that were not affiliated with Chinese-funded
‘CROWN JEWEL’: Washington ‘can delay and deter’ Chinese President Xi Jinping’s plans for Taiwan, but it is ‘a very delicate situation there,’ the secretary of state said US President Donald Trump is opposed to any change to Taiwan’s “status quo” by force or extortion and would maintain that policy, US Secretary of State Marco Rubio told the Hugh Hewitt Show host on Wednesday. The US’ policy is to maintain Taiwan’s “status quo” and to oppose any changes in the situation by force or extortion, Rubio said. Hewitt asked Rubio about the significance of Trump earlier this month speaking with Taiwan Semiconductor Manufacturing Co (台積電) chairman C.C. Wei (魏哲家) at the White House, a meeting that Hewitt described as a “big deal.” Asked whether the meeting was an indication of the
PERMIT REVOKED: The influencer at a news conference said the National Immigration Agency was infringing on human rights and persecuting Chinese spouses Chinese influencer “Yaya in Taiwan” (亞亞在台灣) yesterday evening voluntarily left Taiwan, despite saying yesterday morning that she had “no intention” of leaving after her residence permit was revoked over her comments on Taiwan being “unified” with China by military force. The Ministry of the Interior yesterday had said that it could forcibly deport the influencer at midnight, but was considering taking a more flexible approach and beginning procedures this morning. The influencer, whose given name is Liu Zhenya (劉振亞), departed on a 8:45pm flight from Taipei International Airport (Songshan airport) to Fuzhou, China. Liu held a news conference at the airport at 7pm,
KAOHSIUNG CEREMONY: The contract chipmaker is planning to build 5 fabs in the southern city to gradually expand its 2-nanometer chip capacity Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), the world’s biggest contract chipmaker, yesterday confirmed that it plans to hold a ceremony on March 31 to unveil a capacity expansion plan for its most advanced 2-nanometer chips in Kaohsiung, demonstrating its commitment to further investment at home. The ceremony is to be hosted by TSMC cochief operating officer Y.P. Chyn (秦永沛). It did not disclose whether Premier Cho Jung-tai (卓榮泰) and high-ranking government officials would attend the ceremony. More details are to be released next week, it said. The chipmaker’s latest move came after its announcement earlier this month of an additional US$100 billion
