Kalvoissa

Kalvoissa is a Finnish term meaning “in the membranes.” It is the inessive plural form of kalvo, used to describe localization or events occurring within biological membranes, including cellular membranes or synthetic lipid bilayers.

Etymology and grammar: Kalvo means membrane or film. The suffix -ssa / -ssä denotes the inessive case; the plural form -issa / -issä indicates “in the ….” The word Kalvoissa is thus kalvo (singular), kalvot (plural nominative), kalvoissa (plural inessive). The term appears primarily in scientific Finnish and is common in biology, biochemistry, and related fields.

Usage: In scientific texts, Kalvoissa is used to discuss proteins, receptors, or lipids localized in membranes, or processes that occur within membranes. For example, phrases such as “Proteiinit sijaitsevat kalvoissa” or “kalvoissa tapahtuvat reaktiot” describe localization or activity within membranes, including cellular membranes like the plasma membrane or organelle membranes.

Related concepts: Kalvo (membrane) is the root term, with Kalvoissa indicating location inside membranes. The concept is relevant to studies of membrane proteins, lipid bilayers, transport phenomena, and membrane-associated signaling.

Notes: Kalvoissa functions as a grammatical form rather than a separate concept, but it is widely used in formal Finnish scientific writing to specify intra-membrane localization or events.
