What belongs in this category这个类别收什么
- ANB分析生物化学Analytical BiochemistryThe study of biochemical components found in a cell or other biological sample. The study of the separation, identification, and quantification of chemical components relevant to living organisms.研究细胞或其他生物样品中的生化组分，即对与生物体相关的化学成分进行分离、鉴定和定量。
- GNR普通生物化学General BiochemistryThe study of chemical and physiochemical processes, including interactions and reactions, relevant to living organisms.研究与生物体相关的化学与物理化学过程，包括其中的相互作用和反应。
- MED医药生物化学Medicinal BiochemistryThe study of biochemical processes within the human body, with special reference to health and disease.研究人体内的生化过程，尤其关注其与健康和疾病的关系。
- STR结构生物化学Structural BiochemistryThe study of components, functions, and structures of molecules of cells within living organisms. Projects in this subcategory can address various variables of cells through the theories of Chemistry and the laws of Physics.研究生物体细胞内分子的组成、功能与结构。此类项目可以用化学理论和物理定律来分析细胞的各种变量。
- OTH其他OtherStudies that cannot be assigned to one of the above subcategories. If the project involves multiple subcategories, the principal subcategory should be chosen instead of Other.无法归入上述任何子类别的研究。如果项目涉及多个子类别，应选择项目的主要子类别，而不是选择“其他”。
Judges are assigned by the subcategory you pick, so choose the primary one rather than "Other" where a project could sit in several. Source: Society for Science.评委是按你所选的子类别分配的，一个项目若能落入多个子类别，应选主要的那个，而不是「Other」。来源：Society for Science 官方。 Official page官方页面
Source discrepancy: The 2026–2027 rules book calls this subcategory “Medical Biochemistry”; the website calls it “Medicinal Biochemistry”.官方口径校勘：2026–2027 规则手册中该子类别写作“Medical Biochemistry”，官网为“Medicinal Biochemistry”。

Special-award rate 12.5%; combined 32.5%.专项奖率 12.5%；合并口径 32.5%。
These tier counts exclude 2025, whose award text is missing from the official database. The award-winning projects listed below do include 2025, recovered from the grand-award press release, so the two will not add up.层级分布剔除了 2025 年——该年官方库缺奖项文本。下方的获奖作品清单则包含 2025 年（从大奖新闻稿补回），因此两处数字不会相等。
The gap from the all-track rate of 30.3% is not statistically significant (Fisher exact p = 0.295).与全赛道 30.3% 的差距不具统计显著性（Fisher 精确检验 p = 0.295）。
