AI Thread Summary
H2O, or water, is often debated in the context of biomolecules. While traditional definitions of biomolecules typically emphasize carbon-based compounds found in biological systems, water plays a crucial role in cellular processes. It is integrated into biological systems and is essential for life, leading some to classify it as a biomolecule due to its active participation in these processes. Despite not being organic, water's significance in biological functions supports its consideration as a biomolecule in certain contexts.

Is H2O a biomolecule?

Is H2O a biomolecule?

Not if you define a "biomolecule" as occurring naturally only in certain systems which we refer to as "biological systems" such as proteins. Obviously other molecules enter into biological processes, so if you want to call them "biomolecules" in this context, go ahead. The online definitions are not very discriminating, but they don't mention H2O in the examples I've seen. It's certainly true that water acts as a biomolecule.

Thank you very much.wonderful answer
 
Yes, water has such an active role in cellular processes that it is often considered a biomolecule. Although most biomolecules are carbon-based and water is not organic, it is naturally integrated into biological systems (natural occurrence).

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
