The fatty acid composition of total lipids, triglycerides, free fatty acid pool, esterified cholesterol, phosphatidyl choline, and phosphatidyl ethanolamine of mammary tissue of lactating and nonlactating buffalo has been studied. The distribution of long chain triglycerides, free fatty acids free cholesterol and esterified cholesterol in nonlactating mammary tissue was 76.1,4.2,4 and 0.5 percent of total lipids respectively and in lactating mammary tissue it was 68.3, 1.2, 2.7 and 0.3 percent respectively. Short chain triglycerides constituting about 6.6% of total lipids and could be detected only in lactating mammary tissue. Among phospholipids, phosphatidyl choline, phosphatidyl ethanolamine and sphingomyelin constituted about 39.4, 21.5 and 15.6 percent respectively of total phospholipids in nonlactating tissue and 39.3, 22.6 and 10.7 percent respectively in lactating tissue. All the major fatty acids viz myristic, palmitic, stearic acid oleic were present in various lipid components of both lactating and nonlactating mammary tissue. Linoleic acid was present only in the lactating mammary tissue. Differences were observed in the distribution of fatty acids in lipid components of lactating and nonlactating mammary tissue.
对泌乳期和非泌乳期水牛乳腺组织中总脂质、甘油三酯、游离脂肪酸池、酯化胆固醇、磷脂酰胆碱和磷脂酰乙醇胺的脂肪酸组成进行了研究。非泌乳期乳腺组织中长链甘油三酯、游离脂肪酸、游离胆固醇和酯化胆固醇的分布分别占总脂质的76.1%、4.2%、4%和0.5%，泌乳期乳腺组织中分别为68.3%、1.2%、2.7%和0.3%。短链甘油三酯约占总脂质的6.6%，仅在泌乳期乳腺组织中可检测到。在磷脂中，磷脂酰胆碱、磷脂酰乙醇胺和鞘磷脂在非泌乳组织中分别约占总磷脂的39.4%、21.5%和15.6%，在泌乳组织中分别为39.3%、22.6%和10.7%。所有主要脂肪酸，即肉豆蔻酸、棕榈酸、硬脂酸、油酸，均存在于泌乳期和非泌乳期乳腺组织的各种脂质成分中。亚油酸仅存在于泌乳期乳腺组织中。在泌乳期和非泌乳期乳腺组织的脂质成分中，脂肪酸分布存在差异。
