Okay, I need to create a professional and useful wiki-style document about monosaccharides under the categories of health, nutrition, and carbohydrates. Let me start by understanding the requirements.

First, the structure: H1 for the title, an overview section, several sections with H2 and H3 headings, and maybe references or related documents. The content needs to be accurate, objective, detailed enough, easy to read, and use technical terms with explanations. Also, markdown formatting with proper headings, lists, tables, code blocks if needed, and at least 800 characters.

The title is "단당류" (Monosaccharides). Let me start by outlining the sections. The overview should introduce what monosaccharides are. Then maybe a section on types, their functions, metabolism, health implications, and references.

Wait, the user mentioned "소분류: 탄수화물", so I need to make sure it's under carbohydrates. Also, check if there are any specific points about monosaccharides in nutrition that should be covered.

For the overview, define monosaccharides as the simplest form of carbohydrates, basic units for other carbs. Mention their role in energy and structure. Then, in the types section, list common ones like glucose, fructose, galactose. Maybe a table with their chemical formulas and sources.

Functions: Energy production, structural roles (like in cellulose or chitin), but wait, monosaccharides themselves are not structural; maybe that's for polysaccharides. So focus on energy metabolism. Also, mention how they're absorbed and used by the body.

Metabolism section could explain glycolysis, gluconeogenesis, etc. Maybe a diagram? But since it's markdown, perhaps just describe it. Also, discuss how different monosaccharides are processed—like fructose in the liver.

Health implications: Excess intake leading to issues like obesity or diabetes. But also their necessity. Maybe compare with other carbs, like complex ones. Mention dietary sources and recommendations.

Need to ensure technical terms are explained. For example, "glycolysis" should be briefly defined. Also, check for accuracy—like the chemical formulas of glucose (C6H12O6), fructose same formula but different structure, galactose similar.

References: Maybe include some scientific sources or guidelines from health organizations. But since it's a wiki-style document, perhaps just mention reputable sources without specific citations unless required.

Check for length. Each section should be detailed enough to reach 800 characters. Let me start drafting each part step by step, making sure to use H1, H2, H3 as needed. Avoid markdown in the thinking process but structure it properly in the final answer.
