Where can I find info on molecules; i.e., where they come from, their function, what they do for our body...

Try doing a Google search on "define:molecule".

Or Google "source of molecues"/"function of molecules", etc.

Does that help you?

Molecules are composed of atoms. Here is a site that give some discussion of where molecules come from and some of their uses.

Sorry, I didn't post the site.

To find information on molecules, such as their origin, functions, and their role in the human body, you can start by using a combination of online resources, scientific databases, and textbooks. Here are some steps you can take to gather relevant information:

1. Online Search Engines: Start by performing general searches on search engines like Google or Bing using keywords related to the specific molecule you are interested in. For example, if you want information on "glucose," search for "glucose molecule origin and function."

2. Scientific Databases: Access reputable scientific databases like PubMed, Scopus, or Web of Science. These databases specialize in peer-reviewed scientific literature and contain a wealth of information on molecules, their functions, and their impact on the human body. You can search for the specific molecule you are interested in or explore related articles to gain a broader understanding.

3. Academic Journals: Browse through scientific journals that focus on biochemistry, molecular biology, or pharmacology. Journals like Nature, Science, or Cell often publish groundbreaking research on molecules and their roles in the body. While some journals may require a subscription, many offer free access to abstracts and some full-text articles.

4. Textbooks and Reference Books: Consult textbooks on biochemistry, organic chemistry, or physiology that cover the topic of interest. These books provide comprehensive information on molecules, including their structure, function, and physiological significance. Check your local library or university library for relevant textbooks.

5. Online Educational Resources: Visit educational websites such as Khan Academy, Coursera, or MIT OpenCourseWare. These platforms offer free online courses and resources covering various scientific disciplines, including biochemistry. Explore the relevant course materials or lectures on molecular biology to gain a deeper understanding of molecules.

6. Scientific Organizations and Government Agencies: Explore the websites of scientific organizations and government agencies that focus on health, biology, or biochemistry. Examples include the National Institutes of Health (NIH) or the European Molecular Biology Laboratory (EMBL). They often provide informative resources, reports, and publications related to molecules and their significance in the body.

Remember to critically evaluate the sources you find, prioritize peer-reviewed research articles, and consult multiple sources to ensure accuracy and reliability.
