| EDTA light chain | <protein> Myosin light chains (18 kD) from scallop muscle (two per pair of heavy chains), easily extracted by calcium chelation. Although the EDTA light chains do not bind calcium they confer calcium sensitivity on the myosin heavy chains. (18 Nov 1997) |
| electron transport chain | <biochemistry, chemistry> A series of compounds that transfer electrons to an eventual donor with concomitant energy conversion. One of the best studied is in the mitochondrial inner membrane, that takes NADH (from the tricarboxylic acid cycle) or FADH and transfers electrons via ubiquinone, cytochromes and various other compounds, to oxygen. Other electron transport chains are involved in photosynthesis. (18 Nov 1997) |
| J chain | <molecular biology> A polypeptide chain (15 kD), found in IgA and in IgM joining heavy chains (H chains) to each other to form dimers of IgA and pentamers of IgM. Disulphide bonds are formed between the J chain and H chains near the Fc ends of the heavy chains. Despite the similar name, it is not identical with the J region or coded for by the J gene. Synonym: J piece. (10 Jan 1998) |
| kappa chain | <protein> Either of two types of light chains (small polypeptide chains) that are found in immunoglobulins. (09 Oct 1997) |
| 2-methyl branched-chain enoyl-CoA reductase | <enzyme> Important in the reversal of beta-oxidation under anaerobic conditions in ascaris suum Registry number: EC 1.3.1.52 Synonym: 2-methyl bce-CoA reductase (26 Jun 1999) |
| lambda chain | <immunology> Although light chains are found in many multimeric proteins, L chain usually refers to the light chains of immunoglobulins. These are of 22 kD and of one of two types, kappa or lambda. A single immunoglobulin has identical light chains (2 kappa or 2 lamda). Light chains have one variable and one constant region. There are isotype variants of both kappa and lamda. (25 Jun 1999) |
| lauric acid in-chain-hydroxylase | <enzyme> Specific for lauric acid; hydroxylates at c-8, c-9 or c-10 of chain Registry number: EC 1.14.14.- Synonym: (cytochrome p-450)-dependent laurate in-chain-hydroxylase (26 Jun 1999) |
| L chain | <immunology> Although light chains are found in many multimeric proteins, L chain usually refers to the light chains of immunoglobulins. These are of 22 kD and of one of two types, kappa or lambda. A single immunoglobulin has identical light chains (2 kappa or 2 lamda). Light chains have one variable and one constant region. There are isotype variants of both kappa and lamda. (25 Jun 1999) |
| L-chain disease | bence Jones myeloma |
| L-chain myeloma | bence Jones myeloma |
| light chain | <immunology, protein> The lighter of the two types of polypeptide chains that are found in immunoglobulin and antibody molecules. Also used as a non-specific term for the smaller subunits of several multimeric proteins such as immunoglobulin, myosin, dynein, clathrin. (14 Oct 1997) |
| light chain-related amyloidosis | A form of primary amyloidosis in which the fibrillar amyloid deposits are derived from the amino terminal variable region of the light chains of immunoglobulin; seen in B-lymphocyte and plasma-cells dyscrasias. (05 Mar 2000) |
| long chain | In bacteriology, a continuous line of more than eight cells. (05 Mar 2000) |
| long-chain 3-hydroxyacyl CoA dehydrogenase | <enzyme> Deficiency may cause some cases of hypoglycaemic 3-hydroxydicarboxylic aciduria Registry number: EC 1.1.1.211 Synonym: l-chad (26 Jun 1999) |
