The effect of triglycerides on the growth of Mucor hiemalis and the production of lipase and mycelial lipids was studied. Addition of 1% triglycerides to the fermentation medium was best for the mycelial as well as the broth lipase production. The added triglycerides seemed to be utilized through the formation of free fatty acids, and towards the end of the growth phase most of the triglycerides and their hydrolysis products were utilized. The mycelial lipase activity was maximum (66 U/g dry mycelium) at the end of the growth phase, while the maximal broth lipase activity (204 U/100 mL) was achieved after the cell lysis had started. The lipids produced per gram mycelia were high initially (260 mg/g dry weight at 48 h), reducing gradually later. With increase in growth the maximum mycelial lipids per 100 mL of culture medium was obtained after 96 h (176 mg/100 mL). The various fractions detected in the mycelial lipid extracts were sterol esters, triglycerides, free fatty acids, diglycerides, sterols, monoglycerides, phosphatidyl ethanolamine, phosphatidyl choline, and small amounts of an unknown polar lipid at all the stages of fermentation studied. Proportion between total neutral and total polar lipids remained nearly constant throughout fermentation.

Earthworm Lumbricus

Earthworms (Lumbricus terrestris) were given [1-14C]-labeled palmitic acid by gavage on days 0 and 3, and sacrificed on day 7. The distribution of label among lipid classes indicated that glycerides, sterol esters, cerebrosides, sulfatides, phosphatidylethanolamine, phosphatidylserine and (or) phosphatidylinositol, phosphatidylcholine, and sphingomyelin turn over in, or are synthesized by, the earthworm. Free fatty acids still had the highest specific radioactivity of any lipid class at the end of the experiment. Incorporation of label into sterol and hydrocarbon fractions was insignificant and there was no detectable label incorporated into gangliosides. Phosphatidylethanolamine apparently turned over quite slowly compared with other lipid classes, while the cerebroside fraction became highly labeled. Elongation of palmitic acid to stearate and oxidation to CO2 occurred extensively, but there was no evidence for desaturation.Key words: earthworm, Lumbricus, lipids, gangliosides, metabolism.

Python Molurus Bivittatus

Cast skins of various snakes and in addition one lizard were found to contain 3.5-8.6% extractable lipid material. Lipids obtained from a cast skin of the Indian python were analyzed in detail indicating the presence of hydrocarbons (squalene, cholestadiene and alkanes), monoester waxes, sterol esters, diester waxes, triglycerides, sterols, free fatty acids and even more polar lipids. Among the monoester wax constituents odd-numbered secondary alkanols were found. It is assumed that the above lipids originate from cells of the past integumental generation and that they play an important facilitating role during the sloughing process.

Erythrocyte Lipids

Erythrocytes from mature male cod, which had been starved for 1 week, contained 16.5 × 10−13 g lipid per cell, about 75% of which was phospholipid. Cholesterol represented about 11%, triglycerides 5%, free fatty acids 4%, and sterol esters 2% of the total lipid. The fatty acid composition was typical of a marine lipid, and in general erythrocyte lipids closely resembled cod muscle (cellular) lipid.

Blood Aqueous Barrier

ABSTRACT In addition to the previously described permeability disturbance in the blood aqueous barrier of the eye, measured as an increase of the aqueous flare, a series of transitory systemic effects have been recorded following the subcutaneous injection of synthetic α-MSH: marked increase of the free fatty acids in plasma, decrease in the serum calcium level, decrease in the blood pressure, increase in the skin temperature, increased frequency and diminished amplitude of respiration, presence of slow waves in the EEG. There is a correlation between the magnitude of the aqueous flare increase and the increase of free fatty acids in plasma and also between the aqueous flare and the minimum serum calcium level.
