Macronutrient (Wikipedia)

A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted into smaller molecules in the process of releasing energy such as for carbohydrates, lipids, proteins and fermentation products (ethanol or vinegar) leading to end-products of water and carbon dioxide. All organisms require water. Essential nutrients for animals are the energy sources, some of the amino acids that are combined to create proteins, a subset of fatty acids, vitamins and certain minerals. Plants require more diverse minerals absorbed through roots, plus carbon dioxide and oxygen absorbed through leaves. Fungi live on dead or living organic matter and meet nutrient needs from their host.

Different types of organisms have different essential nutrients. Ascorbic acid (vitamin C) is essential to humans and some animal species but most other animals and many plants are able to synthesize it. Nutrients may be organic or inorganic: organic compounds include most compounds containing carbon, while all other chemicals are inorganic. Inorganic nutrients include nutrients such as iron, selenium, and zinc, while organic nutrients include, protein, fats, sugars and vitamins.

A classification used primarily to describe nutrient needs of animals divides nutrients into macronutrients and micronutrients. Consumed in relatively large amounts (grams or ounces), macronutrients (carbohydrates, fats, proteins, water) are primarily used to generate energy or to incorporate into tissues for growth and repair. Micronutrients are needed in smaller amounts (milligrams or micrograms); they have subtle biochemical and physiological roles in cellular processes, like vascular functions or nerve conduction. Inadequate amounts of essential nutrients or diseases that interfere with absorption, result in a deficiency state that compromises growth, survival and reproduction. Consumer advisories for dietary nutrient intakes such as the United States Dietary Reference Intake, are based on the amount required to prevent deficiency and provide macronutrient and micronutrient guides for both lower and upper limits of intake. In many countries, regulations require that food product labels display information about the amount of any macronutrients and micronutrients present in the food in significant quantities. Nutrients in larger quantities than the body needs may have harmful effects. Edible plants also contain thousands of compounds generally called phytochemicals which have unknown effects on disease or health including a diverse class with non-nutrient status called polyphenols which remain poorly understood as of 2024.

What is this "Wiki" & how does the cannabis community benefit?

The Green CulturED Wiki enables you to explore, learn, and share through a knowledge base tailored to the cannabis industry. It functions like an encyclopedia, lexicon, glossary, wiki, or dictionary. This tool is useful for industry learners and professionals to learn more about resources, programs, and terms specifically in the cannabis sector.

Yes, new terms can be added by crafting individual entries, each with its own dedicated page and unique URL. By sharing resources, information, and industry information, users are able to foster community, growth, and learning. Once submitted, a glossary term is reviewed by the Green CulturED team, which will then approve or deny the submission. 

While the Green CulturED Community Wiki does not impose specific content restrictions, it is essential to adhere to general web content guidelines, which include avoiding misinformation and respecting copyright laws. For cannabis-related glossaries, it’s critical to ensure the accuracy and legality of the information presented. In addition, common courtesy and “netiquette” are part of our community user agreement, and it is crucial to maintain those levels of respect when adding new terms, comments, etc.

Glossary term categories serve as a reference tool that enhances usability, navigability, and educational value by organizing terms into groups such as industry brands, consulting firms, and seed banks.

The Green CulturED Wiki supports comments on individual glossary terms, enabling users to engage in discussions or leave feedback. This feature fosters collaborative learning and knowledge sharing within the cannabis community.
If you encounter incorrect or outdated information, please contact the site administrators directly or use the commenting feature to report inaccuracies for review and correction. Green CulturED Wiki allows for revisions, enabling updates and corrections.
Green CulturED Wiki utilizes user rights and capabilities for managing and reviewing user-contributed terms. Administrators can set specific permissions and establish review processes according to their policies.
