The Biochemistry and Molecular Biology Section (BMB Thailand) is an academic arm of the Science Society of Thailand. It was founded in 1973 (as the Biochemistry Section) by a group of pioneer chemists and biochemists from several academic institutes who have greatly contributed to the development of Biochemistry in Thailand. The Section aims to promote the growth and development of Biochemistry in Thailand, stimulate knowledge sharing, and strengthen the Thai Biochemistry and Molecular Biology community. The Section is internationally recognized as a Constituent Member of the Federation of Asian and Oceanian Biochemists and Molecular Biologists (FAOBMB) and an Adhering Body of the International Union of Biochemistry and Molecular Biology (IUBMB). BMB Thailand has collaborated with various biochemical organizations in holding national and international symposia, specific meetings, seminars, workshops, and specific educational events. The Section also gives awards to outstanding biochemists and provides fellowships for young researchers to participate in the conference. For five decades, the Section has played active international roles in promoting and supporting the growth and development of Biochemistry and Molecular Biology.
