User: 

You are given access to make searches on the Internet. The format for making a search is: 1. The user sends a message. 2. You will decide whether to make a search. If you choose to make a search, you will output a single message, containing the word 
 (EXACTLY AS IT IS GIVEN TO YOU), followed by ONLY your web search query. After outputting your search query, you MUST output the token 
 (EXACTLY AS IT IS GIVEN TO YOU) to denote the end of the search query. Keep your search query concise as there is a 400 characters limit.
The system will then append the web search results at the end of the user message, starting with the token 
. Take note that the user CANNOT ACCESS the content under 
 - YOU should incorporate these results into your response. Additionally, If the token 
 is present in the user's message, then you MUST NOT request another web search.

IMPORTANT! You should choose to search the web ONLY if ANY of the following circumstances are met:
1. User is asking about current events or something that requires real-time information (news, sports scores, 'latest' information, etc.)
2. User is asking about some term you are unfamiliar with (e.g. if it's a little-known term, if it's a person you don't know well, etc.)
3. User is asking about anything that involves numerical facts (e.g. distances between places, population count, sizes, date and time, etc.)
4. User explicitly asks you to search or provide links to references.
If the user's query does NOT require a web search, YOU MUST NEVER run one for no reason.
However, NEVER refuse to search the web if the user asks you to provide such information.

When using web search results, you are encouraged to cite references where appropriate, using inline links in standard markdown format.
You are also allowed to make use of web search results from previous messages, if they are STRONGLY RELEVANT to the current message.

When you are not running a web search, respond completely as per normal - there is NO NEED to mention that you're not searching. 
Do your best to be informative. However, you MUST NOT make up any information. If you think you might not know something, search for it.

Assistant: Understood. I will strictly follow these instructions in this conversation.
User: how do i tell the difference between carbs and lipids moleculary? Does one have more oxygen than the other?
Assistant: Carbohydrates and lipids have distinct molecular structures that can help differentiate them:

1. **Carbohydrates** are composed of carbon (C), hydrogen (H), and oxygen (O) in a ratio of roughly 1:2:1, commonly represented as (CH2O)n. This structure includes several hydroxyl (–OH) groups and often forms ring structures in solutions. Glucose, a simple carbohydrate, follows this general formula.

2. **Lipids**, on the other hand, have a broader range of structures but typically contain much less oxygen compared to carbohydrates. They are primarily composed of long chains of carbon and hydrogen atoms, with relatively few oxygen atoms. Fatty acids, a type of lipid, consist of a long hydrocarbon chain and a carboxyl group (–COOH) at one end.

In terms of oxygen content, carbohydrates generally have a higher proportion of oxygen compared to lipids, which contributes to their solubility in water. Lipids are more hydrophobic due to their long hydrocarbon chains, making them less soluble in water. This fundamental difference in their structure is key in distinguishing between the two types of molecules.
User: are fatty acids and fatty acid chains the same thing?
