The '''nucleoplasm''', also known as '''karyoplasm''',<ref name="Collins_karyoplasm">{{cite web |title=karyoplasm |url=https://www.collinsdictionary.com/dictionary/english/karyoplasm |website=Collins English Dictionary |access-date=2 December 2022}}</ref> is the type of [[protoplasm]] that makes up the [[cell nucleus]], the most prominent [[organelle]] of the [[eukaryotic cell]]. It is enclosed by the [[nuclear envelope]], also known as the nuclear membrane.<ref name="proteinatlas_nucleoplasm">{{Cite web|title=The human cell in nucleoplasm|url=https://www.proteinatlas.org/humanproteome/subcellular/nucleoplasm|website=[[Human Protein Atlas]]|access-date=2025-01-08|url-status=live|archive-url=https://web.archive.org/web/20240915080037/https://www.proteinatlas.org/humanproteome/subcellular/nucleoplasm|archive-date=2024-09-15}}</ref> The nucleoplasm resembles the [[cytoplasm]] of a eukaryotic cell in that it is a gel-like substance found within a membrane, although the nucleoplasm only fills out the space in the nucleus and has its own unique functions. The nucleoplasm suspends structures within the nucleus that are not membrane-bound and is responsible for maintaining the shape of the nucleus.<ref name="proteinatlas_nucleoplasm"/> The structures suspended in the nucleoplasm include [[chromosome]]s, various [[protein]]s, [[nuclear bodies]], the [[nucleolus]], [[nucleoporin]]s, [[nucleotides]], and [[nuclear speckle]]s.<ref name="proteinatlas_nucleoplasm"/>

The soluble, liquid portion of the nucleoplasm is called the '''karyolymph'''<ref name="Collins_karyolymph">{{cite web |title=karyolymph |url=https://www.collinsdictionary.com/dictionary/english/karyolymph |website=Collins English Dictionary |access-date=2 December 2022}}</ref> '''nucleosol''',<ref name="PloS">{{cite journal |last1=Kühn |first1=T |last2=Ihalainen |first2=TO |last3=Hyväluoma |first3=J |last4=Dross |first4=N |last5=Willman |first5=SF |last6=Langowski |first6=J |last7=Vihinen-Ranta |first7=M |last8=Timonen |first8=J |title=Protein diffusion in mammalian cell cytoplasm. |journal=PLOS ONE |date=2011 |volume=6 |issue=8 |pages=e22962 |doi=10.1371/journal.pone.0022962 |pmid=21886771|pmc=3158749 |doi-access=free }}</ref> or '''nuclear hyaloplasm'''.
