# Carbon Atlas — From Food to You

> An independent interactive introduction to nutrients, digestion and metabolism by Shreyam Adhikari.

Published 2026-09-09; updated 2026-09-11. Status: Published. The underlying personal notes date to circa 2024. The article is part of Shreyam's log, not a separate institution or medical service.

The lesson connects food chemistry, absorption, building and storage, ATP production, exercise and exhaled carbon. Its diagrams simplify pathways and are not individual health predictions. Molecular viewers use sourced structures; the amber editorial artwork is conceptual. Andy Galpin's lessons inspired the teaching framework; he is not the author, reviewer or endorser. Scientific citations accompany the explanations.

## Read

- [Complete article in Markdown](https://shreyam1008.com.np/log/metabolism-101/index.md): All thirteen chapters, activity explanations, the nutrient reference, learning checks and scientific sources.
- [Nutrient atlas data](https://shreyam1008.com.np/log/metabolism-101/nutrient-atlas.json): 82 entries grouped by chemistry and context, including a 39-entry core. Includes forms, food examples, handling and source links. The tile count is not a count of universal dietary requirements.

## Topics in the reader

- [Food families and nutrient types](https://shreyam1008.com.np/log/metabolism-101/index.md#food-map): Macronutrients, micronutrients and the adjacent atlas.
- [Digestion and absorption](https://shreyam1008.com.np/log/metabolism-101/index.md#digestion): Intestinal sites, portal blood and lymph routes.
- [Carbohydrates and fiber](https://shreyam1008.com.np/log/metabolism-101/index.md#carbohydrates): Sugar units, linkages, starch and overlapping fiber properties.
- [Fats and lipid transport](https://shreyam1008.com.np/log/metabolism-101/index.md#fats): Triglycerides, phospholipids, saturation, omega families, carriers and body tissue.
- [Amino acids and proteins](https://shreyam1008.com.np/log/metabolism-101/index.md#proteins): Instructed assembly, sequence, folding and function.
- [Storage and later use](https://shreyam1008.com.np/log/metabolism-101/index.md#storage): Glycogen, adipose triglyceride, release and transport.
- [ATP, the Krebs cycle and lactate](https://shreyam1008.com.np/log/metabolism-101/index.md#energy): Carbon counts, electron carriers, oxygen-to-water and reversible lactate reuse.
- [Exercise energy systems](https://shreyam1008.com.np/log/metabolism-101/index.md#context): Phosphocreatine, glycolysis and oxidative metabolism overlap.
- [Where oxidized carbon goes](https://shreyam1008.com.np/log/metabolism-101/index.md#breath): Exhaled CO2 is distinct from energy transfer; breathing faster is not a fat-loss shortcut.

## Optional

- [Interactive article](https://shreyam1008.com.np/log/metabolism-101/): The canonical reading and interaction experience.
- [Scientific sources and original notes](https://shreyam1008.com.np/log/metabolism-101/index.md#sources): Textbooks, official nutrient references, original studies and lesson links.
- [Author profile](https://shreyam1008.com.np/): Shreyam Adhikari.
