L chain

L chain

(Science: 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.

I have got some BIG issues! forgive the long post

... located on the chromosome 6 and contains over 100 genes. The MHC genes are divided into class I, II and III regions. The class I genes encode the chain of the antigen-presenting HLA-A, B and C molecules. The centromeric class II genes, previously known as immune-response genes, encode antigen ...

Re: immunoglobulins

Not exactly sure what the question is. There are 5 types of heavy chains, one for each of the classes of immunoglobulins: IgM, IgG, IgD, IgA, and IgE. Each type of heavy chain has a distinct set of cystine cross-links.

Re: Mitochondrial DNA

... eye color, size etc? As far as I know, no. mtDNA encodes some of the various components for the mitochondria such as the ETC (Electron Transport Chain) proteins such as ATP synthase and it's own ribosomal genes. Here is a pretty good representation of what mtDNA looks like. http://upload.wikimedia.org/wikipedia/commons/3/3e/Mitochondrial_DNA_en.svg
