“…Hence, they remain relatively stable, and a degradation begins only after extended periods of starvation (Chandumpai et al, 1991;Pollero et al, 1991). Sterols, in particular cholesterol, are usually also preserved during starvation (Chandumpai et al, 1991), since they are essential precursors of moulting hormones (ecdysteroids) and, apparently, important also for other processes of larval development and growth (Teshirna et al, 1986).…”

“…Most TAG is synthesized and stored in the hepatopancreas where it constitutes a major energy reserve (e.g., Galois, 1987;Chandumpai et al, 1991;Dall et al, 1992). It can be rapidly mobilized during periods of nutritional, thermal, or osmotic stress (Pollero et al, 1991 ;Chen and Lai, 1993). Shrimp larvae contain apparently less total lipids and, in particular, less TAG than crab larvae.…”

“…Similarly, Pollero, Baró, and Irazú (1991) observed a higher content of total phospholipids (PL) in the muscle, hepatopancreas, and gill tissues of Macrobrachium borellii, as the water temperature decreased. The higher degree of fatty acid unsaturation generally observed in response to decreased temperature takes place mainly in the polar lipid fraction (Chapelle, Zwingelstein, Meister, & Brichon, 1979;Farkas, 1979).…”

Response of proximate and fatty acid (FA) composition of the green tiger shrimp Penaeus semisulcatus in relation to changing water temperatures during over wintering (for 8-weeks at 11-16°C) and then refeeding periods (at 28°C for a further 2-weeks) was investigated in this study. The shrimps did not appear to need to catabolise their either body proteins or lipids during the overwintering period, as the feeding was not ceased completely. While muscle protein, ash and dry matter compositions of the shrimps did not change by changing temperature, lipid increased from 1% during the overwintering period to 1.2% during the recovery period (P<0.01). Saturated FAs (SFA), mono-unsaturated FAs (MUFA), and partially poly-unsaturated FAs (n-6 PUFA) declined, on the contrary, n-3 PUFA significantly rose in the muscle and hepatopacreas during the cold exposure. Shrimps tended to consume especially SFA and, to a lesser degree, MUFA under sub-optimal conditions (P<0.01). PUFA and LC-PUFA appeared to be selectively retained or even elevated in the shrimp muscle during the cold season. Over wintering strategy might generate additional benefit for a heathier food supply for human nutrition, as shrimps can be enriched for LC-PUFA, by simply keeping them under cold water temperatures (10-15°C) during overwintering period, with minimal cost of feeding.

“…During the winter season the TAG content of hepatopancreas comprises more than 80% of the total lipid mass of the organ [2], and in vivo incubation of M. borellii with [ 14 C]palmitic acid revealed that the hepatopancreas is the principal organ for TAG synthesis [3]. The hepatopancreas mobilizes TAG when the animal is deprived of food or subjected to thermal stress [4, 5]. These facts suggest that, in addition to the hepatopancreas’ digestive and biosynthetic roles, it functions to synthesize and store TAG, analogous to adipose tissue in vertebrates.…”

Mammals express four isoforms of glycerol-3-phosphate acyltransferase (GPAT). The mitochondrial isoform GPAT1 may have been the acyltransferase that appeared first in evolution. The hepatopancreas of the crustacean Macrobrachium borellii has a high capacity for triacylglycerol (TAG) biosynthesis and storage. In order to understand the mechanism of glycerolipid biosynthesis in M. borellii, we investigated its hepatopancreas GPAT activity. In hepatopancreas mitochondria, we identified a GPAT activity with characteristics similar to those of mammalian GPAT1. The activity was resistant to inactivation by SH-reactive N-ethylmaleimide, it was activated by polymyxin-B, and its preferred substrate was palmitoyl-CoA. The reaction products were similar to those of mammalian GPAT1. A 70-kDa protein band immunoreacted with an anti-rat liver GPAT1 antibody. Surprisingly, we did not detect high GPAT specific activity in hepato-pancreas microsomes. GPAT activity in microsomes was consistent with mitochondrial contamination, and its properties were similar to those of the mitochondrial activity. In microsomes, TAG synthesis was not dependent on the presence of glycerol-3 phosphate as a substrate, and the addition of monoacylglycerol as a substrate increased TAG synthesis 2-fold. We conclude that in M. borellii the de novo triacylglycerol biosynthetic pathway can be completed in the mitochondria. In contrast, TAG synthesis in the ER may function via the monoacylglycerol pathway.
