Nonanoic acid

Nonanoic acid (Nonoic acid) 是一种天然存在的具有九个碳原子的饱和脂肪酸。它减少细菌易位，增强抗菌活性，并增加猪 β-防御素 1 (pBD-1) 和 pBD-2 的分泌。

Capsaicin, the chemical that imparts the spicy-hot quality of chili peppers, is produced by the fruits of plants belonging to the Capsicum family. 8-methyl Nonanoic acid is an immediate precursor of capsaicin as well as a by-product of capsaicin degradation.[1] Addition of 5 mM of 8-methyl nonanoic acid significantly increases the yield of capsaicin in both immobilized and freely suspended cells of C. frutescens. [2] Capsaicin has reported antimicrobial properties, however isocapric acid can act as a growth substrate in certain bacterial strains.[3]

9-(Boc-amino)nonanoic Acid is an alkane chain with terminal carboxlic acid and Boc-protected amino groups. The compound can be used as a PROTAC linker in the synthesis of PROTACs. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The Boc group can be deprotected under mild acidic conditions to form the free amine.

3-Hydroxy Nonanoic Acid, a hydroxylated fatty acid, is present in the young peridioles of Pisolithus fungi, LPS of P. aeruginosa, bovine milk, and the methyl-branched poly(3-hydroxyalkanoate) (PHA) polymers synthesized by P. oleovorans [Matreya, LLC. Catalog No. 1725].

7-methyl-8-oxononanoic acid is an intermidate for synthesis of conjugated molecules. The acid group can derivatize amine-containing molecules in the presence of activators such as EDC or HATU.

9-(β-D-Galactopyranosyloxy)nonanoic acid 是用于糖生物学研究的重要生化试剂。糖生物学的研究包括糖的结构、合成、生物学功能和演化过程，涵盖碳水化合物化学、聚糖的形成与降解酶学、蛋白质与聚糖的识别，以及聚糖在生物系统中的作用。此领域与基础研究、生物医学及生物技术有着密切联系。

8-Amino-7-oxononanoic acid 是一种有用的有机化合物，可用于生命科学领域的相关研究，其产品编号为 T124817。

4,8-Dioxa-3H-perfluorononanoic acid是一种全氟和多氟烷基物质(PFAS)，具有亲和力并具有对人类孕烷X受体(hPXR)的潜在激动活性。

9-Oxononanoic Acid是一种氧化脂肪酸，由亚油酸自氧化形成，它能提高磷脂酶 A2（PLA2）的活性，并增加离体人体血浆中血栓素 B2 的生成。9-Oxononanoic Acid 能减少肝脏新脂肪酸的合成，并提高大鼠肝脏肉碱棕榈酰转移酶（β-氧化的标志物）的活性。

9-Hydroxynonanoic acid 是一种有用的有机化合物，可用于生命科学领域的相关研究。其产品编号为 T64962，CAS号为 3788-56-5。

Fmoc-9-aminononanoic acid is an alkane chian with terminal Fmoc-protected amine and carboxylic acid groups. The compound can be used as a PROTAC linker in the synthesis of PROTACs and and other conjugation applications. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.

4-methylnonanoic acid是一种 RIFM香料，是一种羊肉中的膻味来源之一。
