a-b and -a chains

Coenzyme Q10 is a component of the electron transport chain and participates in aerobic cellular respiration, generating energy in the form of ATP. In its reduced form, it acts as an antioxidant. Coenzyme Q2 is a precursor of coenzyme Q10 that has 2, rather than 10, isoprenoid units on the ubiquinone base. It can act as an electron acceptor for bacterial Complex I. In mammalian cells, exogenous coenzyme Q2 prevents the production of reactive oxygen species associated with Complex I activity. Forms of coenzyme Q with shorter isoprenoid chains, including coenzyme Q2, induce p53-dependent apoptosis in human B-cell acute lymphoblastoid leukemia BALL-1 cells.

Ganglioside GM2 asialo (asialo- GM2) is a glycosphingolipid containing three monosaccharide residues and a fatty acid of variable chain length but lacking the sialic acid residue present on ganglioside M2. Asialo-GM2 levels are low-to-undetectable in normal human brain, but it accumulates in the brain of patients with Tay-Sachs and Sandhoff disease, which are neurodegenerative disorders characterized by deficiency of lysosomal β-hexosaminidase A and B, respectively. It also binds to various bacteria, including Pseudomonas isolates derived from cystic fibrosis patients. Asialo-GM2 mixture contains ganglioside GM2 asialo molecular species with fatty acyl chains of variable lengths.

Carboxypeptidase B 是一种肽链外切酶，可专一性地降解肽链。Carboxypeptidase B 从 C 端逐个降解，释放出游离氨基酸。Carboxypeptidase B 只水解以碱性氨基酸（如精氨酸和赖氨酸）为 C 末端残基的肽键。

Fibrinopeptide A, human is a 16-residue short polypeptide cleaved from fibrinogen by thrombin. Fibrinopeptide A, human locates at the NH2-termini of the Aα chain.The conversion of monomeric fibrinogen into polymeric fibrin is mediated by thrombin, which b

Proinsulin C-peptide (human) is a 31-amino acid peptide that links the Proinsulin A and B chains, ensuring their proper folding, biological activity, and regulation of cellular functions.

Proinsulin C-peptide human acetate (Proinsulin C-peptide human acetate (33017-11-7 Free base)) 是一种由31个氨基酸残基组成的多肽，它连接胰岛素原的 A 链和 B 链以确保正确折叠，具有生物活性并调节细胞功能。

Human proinsulin, the single-chain peptide precursor of insulin, consists of the insulin A and B chains connected by the 31 amino acid C-peptide. Cleavage of proinsulin by proteolytic enzymes produces insulin and free C-peptide.

Immunoglobulin light chain variable region fragment [Homo sapiens] [Mus musculus] is a fragment on the variable region of the human and mouse immunoglobulin light chain. Immunoglobulins (Ig) are the antigen recognition molecules of B cells. An Ig molecule

Immunoglobulin M heavy chain (IGHM) fragment [Homo sapiens] is a fragment (Gly-Val-Ala-Leu-His-Arg-Pro-Asp-Val-Tyr-Leu-Leu-Pro-Pro-Ala-Arg) on the human immunoglobulin micro heavy chain. Immunoglobulins (Ig) are the antigen recognition molecules of B cell
