Fatty acyl (脂肪酸アシル)


Upper classes: LB

Class Overview

The fatty acyl category includes fatty acids and acyl derivatives of length more than 7. Fatty acids with aliphatic tails of 8–14 are called medium chain fatty acids (MCFA), and those of more than 14 are called long chain fatty acids (LCFA). For shorter ones (SCFA), please go to the Basic Metabolites (BM) category.

Higher fatty acids refer to those of 10 or more carbons. For definition, see IUPAC page.

脂肪族アシルカテゴリーは長さが8以上の脂肪酸やアシル誘導体を含んでいます。長さが8~14のものを中鎖脂肪酸(MCFA)、長さが15以上のものを長鎖脂肪酸(LCFA)といいます。 短いもの(SCFA)は基礎代謝物(BM)カテゴリーに登録されています。

炭素長が10以上のものは高級脂肪酸とも呼ばれます。定義はIUPACを参照してください。

Common Abbreviations よく使う略称

SCFA short chain fatty acids 短鎖脂肪酸 : 1-7 carbons
MCFA medium chain fatty acids 中鎖脂肪酸 : 8-14 carbons
LCFA long chain fatty acids 長鎖脂肪酸 : 15< carbons
SFA Saturated fatty acids 飽和脂肪酸 : no double bond
UFA Unsaturated fatty acids 不飽和脂肪酸 : with double bond(s)
MUFA monounsaturated fatty acids 一価不飽和脂肪酸 : 1 double bond
PUFA polyunsaturated fatty acids 多価不飽和脂肪酸 : 1< double bonds


Classification by Chain Length 鎖長による分類

Fatty acids are extended by polymerization of malonyl CoA, and have even chain length in general.

脂肪酸はマロニルCoAの重合によって伸張し、通常は炭素数が偶数です。長いものほど融点が高くなります。
