Nama e hatselitsoeng e bolela nama e hlabiloeng, e pholileng pele ho tlosa asiti, e leqhoa, ebe e bolokoa ka tlase ho -18 ° C, 'me mocheso oa nama o tebileng o ka tlase ho -6 ° C.Nama e hatselitsoeng ea boleng bo holimo hangata e hoamisoa ho -28°C ho ea ho -40°C, 'me boleng ba nama le tatso ha li fapane haholo le nama e foreshe kapa e hatselitsoeng.
Haeba e leqhoa ka mocheso o tlase, boleng le tatso ea nama e tla fapana haholo, ke kahoo batho ba bangata ba nahanang hore nama e leqhoa ha e monate.Leha ho le joalo, mefuta e 'meli ea nama e leqhoa e na le nako e telele ea ho phela, kahoo e sebelisoa haholo.
Tšusumetso ea likokoana-hloko
1. Mefuta e fapa-fapaneng ea lik'hemik'hale ea lik'hemik'hale e lieha nakong ea metabolism ea lintho tse nyenyane ka mocheso o tlaase, kahoo khōlo le ho ikatisa ha likokoana-hloko li fokotseha butle-butle.
2. Ha mocheso o theoha ka tlas'a ntlha ea leqhoa, metsi a likokoana-hloko le sebaka se potolohileng a hoama, e leng ho eketsang viscosity ea cytoplasm, ho eketsa mahloriso a electrolyte, ho fetola boleng ba pH le boemo ba colloidal ba lisele, 'me ho etsa hore lisele.Kotsi, liphetoho tsena tsa ka hare le tsa ka ntle tsa tikoloho ke sesosa se tobileng sa tšitiso kapa lefu la metabolism ea likokoana-hloko.
Tšusumetso ea li-enzyme
Mocheso o tlase ha o thibele enzyme ka botlalo, 'me enzyme e ntse e ka boloka karolo ea ts'ebetso ea eona, kahoo catalysis ha e emise, empa e tsoela pele butle haholo.Ka mohlala, trypsin e ntse e na le karabelo e fokolang ho -30 ° C, 'me li-enzyme tsa lipolytic li ntse li ka baka mafura a hydrolysis ho -20 ° C.Ka kakaretso, ts'ebetso ea enzyme e ka fokotsoa ho isa tekanyong e nyane ho -18 ° C.Ka hona, polokelo e tlaase ea mocheso e ka eketsa nako ea ho boloka nama.
