spermine

A scientist examines a molecular model of spermine in the laboratory.

Definition

1. Noun:
   • A biogenic polyamine: "spermine" is a crystalline polyamine compound (C10H26N4) found in various living tissues, including semen, where it was first discovered. It plays a role in cellular growth, differentiation, and stabilization of nucleic acids.
   • A biochemical regulator: "spermine" functions as a regulator of ion channels and is involved in processes such as cell proliferation and apoptosis (programmed cell death).

Usage Examples

• (A natural compound found in bodily fluids.)
• (A biochemical substance important for cellular functions.)

Advanced Usage

• "Spermine synthase": an enzyme that catalyzes the production of spermine from spermidine.

  • Mutations in the gene for spermine synthase can lead to developmental disorders. (A specific enzyme involved in spermine synthesis.)

• "Spermine-binding protein": a protein that interacts with spermine to regulate its activity in cells.

  • Spermine-binding proteins help control the levels of free spermine inside the cell. (Proteins that bind to spermine to modulate its effects.)

Variants and Related Words

• Spermidine (n): a related polyamine that is a precursor to spermine.

  • Spermidine is converted into spermine through the action of spermine synthase. (A closely related biochemical compound.)

• Spermine oxidase (n): an enzyme that breaks down spermine.

  • Spermine oxidase degrades spermine into hydrogen peroxide and other metabolites. (An enzyme involved in spermine metabolism.)

Synonyms

• Polyamine: a class of organic compounds with multiple amino groups, of which spermine is a member.
• Biogenic amine: a naturally occurring amine in living organisms.
