The structure of the chain of polyphenylacetylene

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1969
To elucidate the structure of the polymeric chain of polyphenylaeetylenes obtained b~polymerization in the catalytic system TiC1 + AI(C2Hs) 3 (Mn = 5100, 2600) and by thermal polymerization (M n = 1100), we carried out the ozonolysis of the polyphenylaeetylenes in CC14 solution at --30~ The ozonization products were oxidized to acids and these were ...

Mixed‐chain phospholipids: Structures and chain‐melting behavior

Lipids, 2001
AbstractIt has long been established that diacyl phospholipids isolated from animal cell membranes are predominantly of a mixed‐chain variety, meaning that the sn‐1 and sn‐2 acyl chains are saturated and unsaturated acyl chains, respectively. In general, monoenoic and dienoic acids are found in the sn‐2 acyl chain of phosphatidylcholine (PtdCho ...

Multilevel Solutions for Structured Markov Chains

SIAM Journal on Matrix Analysis and Applications, 2000
Summary: A new analysis approach for continuous time Markov chains (CTMCs) with a multidimensional structure is introduced. The presented solution technique employs the multidimensional structure to define aggregated CTMCs that can be analyzed more efficiently.

Structure and Function of the J Chain

1975
Publisher Summary This chapter discusses the role of the J chain in determining the initiation of synthesis, the assembly, and the biologic properties of polymer immunoglobulins (Ig). It is particularly important, because the J chain, via its essential role in IgM polymerization, appears to be a critical factor in the initiation of the immune ...

Primary structure of the A chain of porcine relaxin

Biochemical and Biophysical Research Communications, 1976
The sequence of the B-chain of relaxin, and ovarian peptide hormone isolated from ovaries of pregnant sows, has been shown to have the following primary structure: PCA-Ser-Thr-Asn-Asp-Phe-Ile-Lys-Ala-Cys-Gly-Arg-Glu-Leu-Val-Arg-Leu-Trp-Val-Glu-Ile-Cys-Gly-Val-Trp-Ser (2820 daltons).

Ownership Structure in Agrifood Chains: The Marketing Cooperative

American Journal of Agricultural Economics, 2002
AbstractGlobalization, technological developments, and consumer concerns press farmers and food producers to enhance product innovation and to seek more efficient production and distribution structures. These changes in agrifood markets shift the relative importance of the investments by different chain partners. It may therefore be necessary to change

The Structure of Causal Chains

Sociological Theory, 2018
Sociologists are increasingly attentive to the mechanisms responsible for cause-and-effect relationships in the social world. But an aspect of mechanistic causality has not been sufficiently considered. It is well recognized that most phenomena of interest to social science result from multiple mechanisms operating in sequence.

Structures of Sugar Chains of Ricin D

The Journal of Biochemistry, 1988
The toxic lectin, ricin D, contains mannose, fucose, xylose, and N-acetylglucosamine as sugar components. Sugar chains are linked to Asn-10 of the A-chain, and to Asn-95 and Asn-135 of the B-chain (Funatsu, G. et al. (1978) Agric. Biol. Chem. 42, 501-503; Araki, T. & Funatsu, G. (1985) FEBS Lett. 191, 121-124).

Chain structure of isotactic polyvinyl cyclohexane

Die Makromolekulare Chemie, 1959
Many types of helical chains present in the crystals of different isotactic polymers have been described in the past few years. They all correspond to successions of more or less distorted trans and gauche bonds. The chains of the polymers, which have an identity period along the fiber axis comprised between 6·4 and 6·7 A, generally correspond to ...
