In vivo acetylation of homocholine and b-methylcholine in rat brain

In vivo acetylation of homocholine and b-methylcholine in rat brain. Dick, R. M.; Freeman, J. J.; Kosh, J. W. (Coll. Pharm., Univ. South Carolina, Columbia, SC 29208, USA). Life Sci., 36(12), 1183-8 (English) 1985. CODEN: LIFSAK. ISSN: 0024-3205. DOCUMENT TYPE: Journal CA Section: 2 (Mammalian Hormones) Section cross-reference(s): 13 A N-P-gas chromatog. procedure was modified to det. the extent of in vivo acetylation of the choline analogs homocholine [10238-59-2] and b-methylcholine [7562-87-0]. Infusion of homocholine (18 mmoles) for 2 h into the lateral ventricle of the rat produced 2.3 nmoles/g of acetylhomocholine [10172-82-4] by which represented 0.035% of the detected homocholine. Infusion of the same quantity of b-methylcholine produced 1.0 nmole/g of acetyl-b-methylcholine [55-92-5] representing 0.025% of the detected b-methylcholine. Although pretreatment with hemicholinium-3 reduced the amt. of acetylated product formed from either analog, the redn. was significant only for acetyl-b-methylcholine.

Substitution of choline by related compounds in the diet of Argyrotaenia velutinana and Heliothis virescens

Substitution of choline by related compounds in the diet of Argyrotaenia velutinana and Heliothis virescens. Hodgson, Ernest; Ligon, Betty G.; Rock, George C. (Dep. Entomol., North Carolina State Univ., Raleigh, N. C., USA). J. Insect Physiol., 23(7), 801-4 (English) 1977.Some chemicals with cas registry numbers like 62-49-7 are also used. CODEN: JIPHAF. DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) A. velutinana and H. virescens both required choline [62-49-7] for growth and development when reared on semisynthetic diets, the optimum levels being 50 and >100 mg/100 g of diet resp. No choline analog tested replaced choline adequately. Dimethylethylcholine [13205-69-1] allowed some adult emergence but development was slower and mortality higher than with choline. There are some commonly used reagents like 62-49-7 in this article. In A. velutinana, dimethylisopropylcholine [21618-44-0] and b-methylcholine [7562-87-0], although inadequate as choline replacements can spare the dietary choline requirement. Isopropylethanolamine [109-56-8] was a growth inhibitor for A. velutinana but not for H. virescens. ..
