The effect of temperature on postprandial metabolism of yellowfin tuna (Thunnus albacares)
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2016Specific dynamic action (SDA), the increase in metabolic expenditure associated with consumption of a meal, represents a substantial portion of fish energy budgets and is highly influenced by ambient temperature. The effect of temperature on SDA has not been studied in yellowfin tuna (Thunnus albacares, Bonnaterre 1788), an active pelagic predator that

A Candidate Magnetic Sense Organ in the Yellowfin Tuna, Thunnus albacares
Science, 1984Single-domain magnetite crystals have been isolated and characterized from tissue located in a sinus within the dermethmoid bone of the skull of the yellowfin tuna, Thunnus albacares . Their chemical composition, narrow size distribution, and distinctive crystal morphology indicate that these crystals are ...

Lens iso-precipitin in yellowfin tuna (Thunnus albacares)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1972Abstract 1. 1. Electrophoresis has been commonly used in the analysis of nuclear eye lens extracts for intraspecific variation. 2. 2. Experiments with extracts from yellowfin tuna indicate the presence of an iso-precipitin which may provide a simpler, but equally precise method.

Muscle iridescence in yellowfin tuna (Thunnus albacares)
Food Research International, 2012Microscope spectrophotometry was used to investigate strong iridescence in yellowfin tuna steaks. Iridescence was restricted to the axes of transversely sectioned myofibers. Sometimes groups of adjacent myofibers all had the same iridescent colors, but colors sometimes differed between adjacent myofibers; thus, myofibers were optically isolated ...

Isolation and characterization of metmyoglobin reductase from yellowfin tuna (Thunnus albacares)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1985The isolation, purification, and characterization of metmyoglobin reductase from yellowfin tuna (Thunnus albacares) is described. The enzyme has been purified 120-fold. Characterization of the enzyme includes molecular weight, isoelectric point, substrate specificity, enzyme kinetics, chromatographic behavior, and sensitivity to inhibitors.

A unique selenoprotein isolated from yellowfin tuna (Thunnus albacares) liver
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1986A selenoprotein, with an approximate molecular weight of 2000, was isolated from yellowfin tuna (Thunnus albacares) liver. The selenium (Se) content of this selenoprotein fraction represented greater than 50% of the Se in the original liver extract. Most of the unrecovered Se was left in the pellet following homogenization.

Characteristics of collagens from the swim bladders of yellowfin tuna (Thunnus albacares)
Food Chemistry, 2014Acid soluble collagen (ASC) and pepsin soluble collagen (PSC) were extracted from the swim bladders of yellowfin tuna (Thunnus albacares) with yields of 1.07% and 12.10%, respectively. Based on electrophoretic patterns, both ASC and PSC consisted of two α-chains (α1 and α2) and were characterised to be type I collagen. ASC had higher β-chains than PSC.

Purification and characterization of an aminopeptidase from tuna (Thunnus albacares) pyloric caeca
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1994An aminopeptidase was purified from a water soluble fraction of tuna pyloric caeca by heat treatment, Zn2+ fractionation, ion exchange on a DEAE cellulose column, gel filtration on Fractogel TSK-55, and immobilized metal ion affinity chromatography (IMAC) on IDA(Cu2+/Zn2+)-Sepharose 6B.
