Okay, I need to create a Wikipedia-style document about "Galactose" under the categories of Health, Nutrition, and Nutritional Supply. Let me start by understanding what galactose is. From what I remember, it's a type of sugar, specifically a monosaccharide. It's part of lactose, which is milk sugar. But I should verify that.

First, the structure: H1 for the title, then an overview section. Then sections with H2 and H3. Maybe start with what galactose is, its chemical structure, sources, metabolism, functions in the body, related conditions, and maybe some references.

I need to make sure the information is accurate. Let me check if galactose is indeed a monosaccharide. Yes, it's one of the simple sugars. Its formula is C6H12O6, same as glucose but different structure. That's important to mention.

Sources: primarily from lactose in milk. But also found in other foods? Maybe some fruits or vegetables? I should confirm that. Also, how does the body process it? It's metabolized into glucose through glycolysis, right?

Functions: energy source, but also involved in other processes like cell signaling or as a component of glycoproteins. Wait, maybe that's more for galactosyltransferases. Need to be precise.

Related conditions: Galactosemia is a genetic disorder where the body can't process galactose properly. That's a key point. Symptoms include jaundice, liver damage, etc. Also, lactose intolerance vs. galactosemia—different issues. Lactose intolerance is about lack of lactase enzyme, while galactosemia is a metabolic disorder.

I should mention the importance of dietary management for those with galactosemia. Maybe also note that it's not just milk products but other sources too.

Need to avoid technical jargon where possible, or explain terms if used. For example, "monosaccharide" can be explained as a simple sugar that can't be broken down further.

Check the length: need at least 800 characters. The current draft seems okay, but I should expand each section with more details. Maybe add a section on metabolism steps, or how it's absorbed in the body.

Also, include references or related documents. Maybe link to lactose, galactosemia, or other sugars like glucose and fructose.

Wait, the user mentioned "영양 공급" which is nutritional supply. So focus on its role as a nutrient, how it's supplied through diet, and its importance in nutrition.

Make sure each section flows logically: introduction, chemical properties, sources, metabolism, functions, related disorders, dietary considerations.

Check for any inaccuracies. For example, galactose is not found in significant amounts in other foods besides milk? Or are there other sources like certain vegetables or fruits? Maybe some legumes or plants have small amounts?

Also, mention that it's a component of glycolipids and glycoproteins, which are important for cell structure and function.

In the metabolism section, explain the steps: absorption in the intestines, conversion to glucose via the liver, then energy production. Also, the role of enzymes like galactokinase and UDP-glucosyltransferase.

For related disorders, maybe mention the different types of galactosemia (like classic vs. other forms) and their treatments.

I think that covers most aspects. Now structure it with H1, H2, H3 headings, use bullet points or lists where appropriate, and ensure clarity.
